Presentation

Red dot sights have become extremely popular, and I consider myself an enthusiast on the topic. You might have read my last comparison between theVortex Defender XL VS. the Holosun 507 Comp, two large windowed XL red dots. Today we are looking at two micro red dots in the same way. We are reviewing the Vortex Defender CCW VS. Holosun SCS Carry, both of these red dots are RMSc footprint compatible, and they both feature an enclosed emitter.

They are very comparable and I expect very popular candidates for folks looking to put a red dot on their CCW pistol. I’ve put quite a few rounds through both of them, and today I’ll give you my opinion on their comparison.

Specifications

On paper these two sights are pretty similar, the main difference in construction being that the Defender uses a dual power source. A removable CR2023 battery whereas the Holosun uses its solar panel as a source, keeping an internal battery (non-serviceable) battery charged.

vortex, vortex optics, defender CCW, enclosed, red dot, battery, cr2023, — the easily removable CR2023 battery of the Defender

Both of these are small and ideal for a CCW pistol, but because they are enclosed emitters that means they are slightly bigger than traditional open emitter red dots. The Vortex defender is a little bigger than the SCS Carry, though I’m not sure if thats because of the battery housing or because they wanted to make a bigger window.

Configurable reticles are becoming more the norm, and I like that. Both of these can be configured with a dot, circle, or circle-dot reticle.

On the Range

I’ve spent a lot of time shooting with both of these sights, but in fairness I have more time using the Holosun. I have run the SCS Carry on several different pistols, both 9mm and .22LR. The Defender CWW Solar Micro has lived on my Girsan 2311 since I got it. Realistically though, you can get to know a pistol sight well enough without having to go through a bunch of pistols. Though I did run both sighs on the same pistol for a while to get a solid comparison.

Mounting and Zeroing

The Holosun SCS Carry uses a K footprint, that can also be dropped onto an RMSc footprint. The Defender is an RMSc footprint, so either of these can fit in most of the same mounting situations. I had not issue mounting them on several different similar pistols.

holosun, scs, carry, red dot, holosun red dot, — unboxing the Holosun SCS Carry

When mounting red dots, I usually try and line them up as close to the iron sights as possible before torquing them down. This usually makes for minimal adjustments to zero the sight. The Vortex model has 110 MOA of adjustment available, while the Holosun is plus or minus 30 MOA. That might make the Vortex a little better for certain host weapons, but in general you probably don’t need that much.

The Vortex also gets extra points since it came with a plethora of mounting screws and accessories for mounting on different hosts.

Brightness

One very convenient thing about the SCS Carry is its auto-brightness correction. The solar panel uses ambient light to adjust the reticle brightness. I really like this feature though every so often I wouldn’t, let me explain. Typically in dark areas, I occasionally found that the SCS Carry was a touch dimmer than I would have liked in such a scenario. Outside in daylight I never had an issue.

The Vortex Defender has a manual brightness adjustment, which can be both good or bad. You can set it where you want it, and know what to expect everytime you present the pistol. But you also might have it set a little bright, or a little dim for any particular scenario. I am still unsure which way I prefer, but I kind of default to the manual setting, because I like control.

Sight Picture

Both of these optics are compact, though the Defender is a touch bigger as I mentioned. But the Defender also has a noticeably bigger window, and a little bit means a lot with sights this small. The bigger window definitely gives more room for target acquisition and aiming. Both of them gave precise aiming, but I think I have to give the Defender an edge here.

One thing worth mentioning here, the Holosun SCS Carry does incorporate a notch rear sight as part of its housing. Which is one thing I wish the Defender had, in case the electronics were to fail.

Parallax and Clarity

One thing I noticed with the SCS carry from the very first time I mounted it, was a touch of fuzz when focusing on it. I never worried too much about it as I would look past the sight at the target, and hold the reticle over it. Doing this I never had any issue sharply seeing the reticle.

On one of my test guns, I removed the SCS to install the Defender and immediately noticed the Vortex did not have that issue. Regardless of where I focus the Vortex Defender is sharp and clean, whereas the Holsun SCS Carry did have a little fuzziness depending on how you looked through it.

Accuracy and Zero

With 3 and 2 MOA dots, both of these optics give you a fine aim point. And with an accurate firearm I found them both to be very useful. When zeroing the optics I found they were smooth, and moved evenly. I can’t stand a sight that doesn’t show any change when you adjust it, and both of these were great in that aspect. The quality of these two sights also show in that neither of them needed to be re-zeroed at any point, they held zero nicely, and after hundreds of rounds they hadn’t moved.

Value

I have no doubt that both of these optics are manufactured overseas, it’s hard to find a red dot that isn’t these days. To be honest I was a bit surprised that the Holosun tends to cost more at popular online retailers. At publishing, it seems the SCS Carry is usually around $400 like here at Primary Arms. While the Vortex Defender CCW Solar Micro is typically priced around $300 like here at Optics Planet. With prices like that, the Vortex seems to offer a significant advantage.

Report Card

You may have gathered, I like both of these sights. But it didn’t surprise me that the Vortex won me over, after a short while shooting it I could tell I was going to like it more than the Holosun SCS Carry. That is certainly not to say the SCS Carry is not a good option as well. Though I like them both I would have to pick the Defender CCW Solar Micro if I had to pick only one. Luckily I don’t, and I can have both of them for different purposes.

Last Words

Hopefully this has helped you decide which of the two options might best fit you. Both are certainly good choices for your concealed carry pistol, but it would be a good idea to look at them in person as well to help close the deal for you. Both of these dots will continue to be used in my collection, and I look forward to what’s new from both of these great companies.

Low Power Variability: The Mueller Optics 2.5-10×44 Tac III

April 1, 2026Optics, Product reviewFfp, lpvo, mueller, mueller optics, scope, tac 3, tac IIIcoldboremiracle

Introduction

The Mueller Optics Tac II rifle scope came out to fill a purpose between tactical shooting and everyday hunting. That idea has been revisited now with Mueller’s new 2.5-10×44 Tac III. Today we are taking a look at one of these scopes, to see how it fits into the dual roles. We’ll test the scope on various rifles, and bring you our best informed opinion on it. With that said, lets get into the review of the Mueller Optics 2.5-10×44 Tac III.

Mueller, mueller optics, tac III, 2.5-10, riflescope, scope, ruger, .22lr, ruger precision rimfire,

Mueller optics 2.5-10×44 Tac III

The Tac III riflescope has received so significant upgrades. Starting on the foundation of a 30mm tube, which has become the minimum standard for tactical riflescopes. The larger tube supports a 44mm objective lens, which is a little smaller than many tactical scopes. Perhaps for a lower profile.

Inside the scope you will find a first focal plane reticle, which means the reticle will change size depending on the magnification setting. This has become a conspicuous trait of tactical scopes, as it allows quicker use of the reticle for measuring downrange details. And using these details for on-the-fly corrections.

The capped turrets can be used for zeroing the scope as well as dialing corrections. They are graduated in 1/4 MOA clicks which are very popular with hunters. The fine scale allows for precise corrections. Mueller uses what they call camera grade lenses, for precise images for accurate engagements.

Out of the Box

After my initial inspection, finding all the included accessories and such. I decide to mount the scope first off on one of my .22lr rifles, as this would allow plenty of inexpensive shooting to test the functions of the scope.

I would mount the Mueller to my Ruger Precision Rimfire rifle, using a ZRO Delta 30mm Cantilever mount. These two went together nicely with a perfect height for the rifle. Once mounted I spent some time looking through the scope to get a feel for it. The initial clarity and sharpness of the scope was nice. And with it mounted properly I was excited to get outdoors and put the scope to work.

On the Range

With a target setup at 50-yards, I did a quick boresight job on the rifle and scope. And after loading a magazine I fired a few shots to see how close I was. It only took a couple additional adjustments before the little rifle was hitting everything I put the crosshair to. I stretched it out a bit further and I was very impressed with how consistent this combination was. It didn’t take long to figure out corrections for one-hundred, one-fifty and two-hundred yards. There was too much fun to be had. I zeroed the turrets of the Mueller Tac III, to ensure things would stay this predictably fun.

Accuracy

Adjustments of the Mueller Tac III were crisp and consistent. And they matched the values shown on the FFP reticle. The sharpness of the imagery in this scope made for very precise shot placement. I found myself taking tiny white pebbles out of a hillside some 115 yards out. And dialing corrections would make holding dead center an easy option.

I am a huge fan of FFP scopes, and the execution on the Mueller Tac III is fantastic. I prefer MRAD over MOA, perhaps someday they’ll produce that option as well.

Tracking the scope across its full sweep of movement showed a smooth return to where it started. Accurate erector movement made the corrections line up with predictions.

Reliability

So many scopes these days are manufactured in Asia, even though they may have higher quality components from elsewhere. You can’t blame people for being suspicious of product quality coming from such places, though there seems to be a huge improvement recently. So far, I see nothing in the Mueller Tac III that suggests it won’t perform very well. I have drug it all over the hills here, bounced it around on the back of an ATV and it hasn’t lost zero or its great image quality.

Quality

Lower magnification optics tend to suffer less from optical aberrations. But adding the FFP option of this scope throws a level of complexity back into its construction. With that said I can say the optical quality of this scope is much nicer than my pictures can show. That said, keep in mind that this scope is priced under $300. For that price I think its quality is at or above its price point.

Value

Looking at similar optics in similar configurations, there isn’t a lot of competition. Mainly its competition comes from low power variable optics (LPVO) that have 24 and 28mm objectives. These aren’t going to have as bright and impressive an image as the Mueller Tac III with its 44mm. And the few options that are also FFP like this one come from other brands mainly unknown and unproven in the US market.

With an MSRP of $299 this scope is neither Temu trash tier, nor is it unreachable for the masses. It offers a great optical performance and FFP reticle without having to spend a lot of money.

Pros and cons

I like this scope quite a bit, it has handsome good looks which goes a long way. The imagery seen through it is even better though. The sharp details are very nice, making this rifle seem even more accurate. It’s a great match for this 22lr, but would also do very well on a centerfire rifle. I usually prefer dialing turrets over holding over, but with this scope being an FFP I am more likely to use its reticle for holding over instead. Especially since it uses MOA versus my preference of MRAD.

Docking a few points from the Mueller Tac III results from few things; First off is the illumination. It is challenging to make an LPVO with FFP and great illumination, and the Tac III shows that. In bright daylight, I found the illumination to be okay. If you are running the scope at low power for fast sighting the illumination would be more helpful if it was brighter. It does have off settings between each brightness setting, which is a plus.

I guess this isn’t exactly marketed as a long-range optic, but it does use some features useful in long-range shooting. The 30mm tube is pretty standard for such shooting, and having a reticle designed for hold-over corrections on longer shots would suggest it could be purposed on at minimum a medium range rifle. I’d prefer it had adjustable parallax as that would make it much better for that purpose. But this feature also has to be weighed against price as well, because adding adjustable parallax would increase the cost.

My conclusion

With medium range carbines becoming ever more popular, scopes in this range have gone up in demand quite a bit. I find the Mueller Tac III to be a significant improvement over the Tac II, but it does find itself in a flooded market full of other great options as well. I found this scope to be a great companion to my 22, and I also think it would do very well on a medium range carbine or hunting rifle. As competition in this market grows, I expect Mueller Optics will continue to adapt their offerings to customers needs and budgets.

Walker Game Ear Suppressor Bluetooth Earbuds

March 30, 2026Ancillary gear, Electronics and Tech, Product reviewbluetooth, earbuds, earplugs, hearing protection, suppressor earbuds, walkers game earcoldboremiracle

Preface

Technology continues to work into our shooting experience. And today I present to you another new to me product that brings more electronic gizmos into the shooting realm. Our subject today is the Walkers Game Ear Suppressor Bluetooth Earbuds. These are electronic bluetooth earbuds that have the noise cancelling Walkers is famous for, with all the added benefits that your typical earbuds also give.

Walkers Game Ear Suppressor

Walkers is famous for the ability to not only protect your hearing, but amplify your surroundings at the same time. This has typically been more for hunters than shooters. The Suppressor Bluetooth Earbuds offer the next level of both protection, situational awareness, and even entertainment.

With omnidirectional stereo sound from four microphones, the Suppressors give you 25 DB protection from gunfire. While also providing you connection to your surroundings, and even the ability to enhance those sounds.

Not only does it come with various sizes of foam and silicone tips for maximum comfort, they also allow four different frequencies of sound to customize your hearing experience. All this in a wireless rechargeable earbud set much like those all the cool kids are wearing these days. And like the popular kids, you can charge these up to three times in their discreet battery powered case. The case can also be charged via a USB-C included cord.

As if all that wasn’t enough, you can customize your listening experience on the fly using the Walkers Link 4.0 application on your phone to adjust balance, volume and the differential between your favorite tunes playing by bluetooth and the ambient noise around you.

Controlling the Suppressor Earbuds

Aside from directly operating the earbuds through the app, you can also adjust the volume, skip songs, and change hearing settings all by touching the control surfaces on the exterior of the earbuds.

You can also adjust the auto-off setting between 2, 4, and 6 hours. Or not at all. You can balance between your ears if you choose as well.

Sound Quality

As an earbud, these are fantastic. The quality of the music sound played from my phone is as good as other comparably priced earbuds I borrowed from my wife.

Additionally, the sounds picked up by the microphones are also impressive. As I type this out, I can hear the keystrokes over the music playing at an aggressive volume. I could also hear my wife’s phone playing a video inside another room with a closed door.

Fit and Feel

The various ear canal gaskets give you various options. I tend to prefer the foam ones as the silicone ones seem to work loose on me. The foam plugs are a bit stiffer and keep a good grip inside your ear, aided by the rubber rib mounted under the plug. If you have sensitive ears, the silicone plugs might be better as they don’t press out against your ear canal as hard.

These Suppressor Earbuds do stick out a little further than I’d like. Its not like I’m gonna be snagging them against tree limbs or something. But they are out there enough that you could brush them loose when adjusting your beenie or glasses. This is certainly not a deal breaker, but something to be aware of.

On the Range

I’ve used these earbuds on the range several times now, in addition to my wearing around the house and office to listen to music. They do a great job keeping the noise of firearms down. As someone who wore foamie ear-plugs for the majority of my shooting career, these feel like they cancel the noise just as good as any foamie might. With the added benefit of being able to hear those around you, in stereo. It also allows me to listen to John Wick Mode by Castlevania while I do reloads with my Staccato.

Pros and Cons

There are very few cons that I found with these earbuds. I mentioned the slight protrusion from the ear, and the possibility of the foam pressing out against your ear canal. Other than that I can confidently say they knocked it out of the park with these earbuds. I remember nearly a decade ago paying twice this much for custom fitting electronic ear protection. Only to find within the first few minutes that they were slightly worse than foamies, and were always dead with expensive batteries.

In Closing

My conversion to electronic hearing protection is fairly recent. But I don’t think I’ll be using foamies anytime soon short of an emergency. I quite enjoy these earbuds, and look forward to more days at the range wearing them. If you are looking for electronic hearing protection, these might be right up your ear canal, especially if you like accompaniment.

Mueller Optics 6-24X50 TacHunter Rifle Scope

March 27, 2026Optics, Product reviewmueller, mueller optics, tachuntercoldboremiracle

Preface

I remember seeing Mueller Optics advertised for years, apparently as far back as 2007 when the company came to market. During all this time, I never took the chance to try one of Mueller’s products. For one reason or another I never got the chance, until now. And today I bring you a review of my first experience with Mueller Optics, with their Mueller Optics 6-24X50 TacHunter Rifle Scope.

Mueller Optics

I mentioned Mueller Optics has been around for nearly twenty-years, but it seems longer than that to me. Either way, the company has long had the mission to bring quality optics to consumers at a price that leaves room for other things.

California based Mueller Optics offers a variety of different scopes, from almost every different size and style. Everything from small low power variable optics (LPVO) up to high magnification long-range rifle scopes like the one we are looking at today.

The Mueller Optics 6-24X50 TacHunter

Based on its name, I believe the TAC hunter line of scopes is directed towards tactical style shooters and hunters. It fits many of the features that both parties look for in a rifle scope. Built on a 30mm tube with a 50mm objective lens, the TacHunter has the right proportions. The 30mm tube allows for greater internal mechanical travel, making long-range corrections possible. And the large 50mm lens compresses light and imagery together for a crisp image.

When I opened the box I was initially concerned because I heard a rattle inside the scope. Thinking maybe something had broken I investigated, and found it was just the zero-stop ring hadn’t been tight enough. So the problem was short lived and easily remedied. The zero-stop functions by tightening against the turret stem, and it engages a post on the base of the housing.

Further inspection of the scope showed good tension on the turrets and magnification ring. Though there was a tiny touch of a rubbing sensation when adjusting the magnification. The SFP reticle was very sharp and clear. As I looked through the scope, I adjusted the parallax to get a very sharp image of both reticle and downrange.

Illuminating the reticle is done with a typical twist rheostat next to the parallax knob. There are 11 brightness settings but only one off setting, and the entire reticle lights up (except for the posts).

Matching to a Rifle

I went for a Primary Arms cantilever 30mm scope mount, because I planned on mounting the scope on an AR15 upper. This one is a little different than your typical AR though. The host rifle for this scope would be a hybrid of my Bear Creek Arsenal bolt-action 5.56 upper mated to my Desert Tech Quattro 15 Lower receiver. I mainly did this because it has a good trigger in it, and I’m a sucker for good triggers.

The bolt-action AR upper has proven to be very accurate for me in the past, so I figured the combination would work great together with the Mueller TacHunter. It would make a nice little varmint rifle anyways. Once mounted and leveled it was ready for the range.

Shooting with the Mueller TacHunter

In the snowy spring mountains, I would do some exploring with the Mueller. It was a bit early for hunting my typical springtime marmots, so I would end up simply shooting at various targets within my range. The big spaces would certainly allow plenty of opportunity to look at things through the Mueller.

As I lay on a shooting pad, settled in behind the rifle I began searching for suitable targets. I typically use first focal plane scopes, it’s been a minute since I had used a second focal plane scope. I’d forgotten how pleasantly simple they are, and this one in particular was very clean (if you wan’t to know more about FFP & SFP go read this next). My ability to focus both the image and reticle was impressive, making me really wish I was laying in front of a prairie dog town or something.

Removing parallax with this scopes turret felt very precise. Over the broad magnification range I found it was very easy to find a sweet spot where the fine reticle had sharp contrast over the target. This is a very useful feature when shooting long-range, as many looking at this scope might do. Removing parallax is simply part of long-range shooting, and if you need to learn more about the subject you can go read more about parallax here.

Other Adjustments

On top of the Mueller TacHunter, there is an exposed elevation turret. With 1/4 MOA click values, the turret moves 15 MOA per rotation. That is approximately enough to take your average rifle out to about 600 yards. For that reason I like turrets with a touch more elevation per rotation. But the TacHunter redeems itself with a zero-stop. In the old days before zero stops we had to keep track of whatever revolution of the turret was zero for the rifle. This was further complicated by turrets with more rotations. For example if your scope has only two rotations, even if you guess which one you’re on you have a 50/50 chance. Zero-stops brought an end to this madness by making it easy to just turn in the down direction until it stops. And since you the user could set the stop, you could make it 100 yards or 200 yards or whatever you desire.

Once you zero the rifle, you can remove the screw that secures the turret using a coin or something similar. Underneath you can set the zero-stop, and then reset the turret at zero before snugging down the screw again.

The windage adjustment is capped, which is not an uncommon practice these days. It is typically used less often than the elevation turret, normally just for zeroing the rifle. Opposite the windage is the elevation control on top of the parallax knob. It’s pretty self explanatory, especially if you are looking through the scope. The hollow posts of the reticle don’t light up with the reticle itself, I like that as it reduces too much light when the reticle is lit. And without illumination, the hollow posts allow you better perspective of the target area.

Tracking in the TacHunter

I measured the tracking of the turrets and reticle to see how they matched up on paper. Modern manufacturing techniques make it much easier to ensure a scope is actually moving the amount it says it does. Additionally, I wanted to make sure it not only moves what it says, but also returns to where it supposed to.

mueller, mueller optics, tachunter, 6-24x50, scope, reticle, reticle, tracking,

In my examination, the Mueller TacHunter exhibited accurate and corresponding movements on both the turrets and the reticle. Measuring a distance with the reticle, and dialing that amount with the turrets would make a corresponding correction. Dialing the scope up and down during various shooting trips would show the reticle return to the same spot.

Pros and Cons

Let’s start out with a couple things I would change about this scope. I do like this second focal plane version, but I am more of a first focal plane kinda guy. So it would be awesome if Mueller would produce an FFP version of this scope. The exact same thing could be said about MOA versus MRAD, I’d like this scope even more if it was MRAD like my other scopes. And unlike making an FFP version of the scope, the cost differential would be minimal.

The illumination might be a little better suited if less of it was illuminated. With the entire reticle being lit up, it can be a little overpowering to your eye in low light conditions where it will be used. I also wish there was more than one “off” position for the illumination.

On the plus side, this scope is very affordable, with nearly every model from Mueller being under $300. I will say that only a little more you can likely get something very comparable or perhaps better.

The high quality lenses that Mueller Optics uses in these scopes definitely shows, as the images are very bright and clean. And the sharp focus and parallax adjustments make it very easy to see fantastic images. The reticle is very fine and useful for precise shooting and measuring. I think this scope is going to stay on one of my varmint rifles for sure.

Conclusion

Despite the few things I would change about this scope, I still think it has great use on your precision varmint rifle or something comparable. It gives a fantastic view through the scope with great visual refinement. While its mechanical features might be a touch behind the times compared to the rest of the market, I still find it very useful in my collection. And I look forward to stacking piles of furry little bodies with it later this spring.

Years of Suppression with the SilencerCo Omega 300 Suppressor

March 25, 2026Product review, suppressorsomega, omega 300, SiCo, silencer, silencerco, suppressorcoldboremiracle

Prologue

SilencerCo’s Omega has been a stalwart in their line up for some time, over a decade actually. The Omega offers a variety of modularity and adaptability, and its continuous manufacture would suggest that the shooting public likes what it has to offer. So today we are taking a look at one of SilencerCo’s most successful models; the SilencerCo Omega 300. It has seen some changes over its lifetime likely, but today we’ll see what makes it tick, and why shooters keep buying it.

The SilencerCo Omega 300

One could argue the Omega has been the backbone of SilencerCo’s 30 caliber suppressor line. The Omega features a fully welded lightweight core, with a modular hub and muzzle cap. With its iconic anchor brake users can reduce recoil, or swap it out for a traditional muzzle cap. Various Bravo style mounting options allow you mount the suppressor however you see fit. Direct thread options or any of the ratcheting lock style muzzle devices can also be incorporated to the Omega’s breech.

Whether you use the Omega for a 5.56 full-auto carbine, or for your precision 300 Winchester rifle, there is great compatibility. Generous barrel limitations make the Omega a good choice if you are an SBR enthusiast. When you buy the Omega 300, it comes with a Bravo 5/8-24 threaded hub for direct threading to your muzzle. As well as the tools needed to change out the hub.

I am no stranger to the Omega 300, not only have I used them on various occasions but a good friend of mine has been using one for nearly a decade. It has been along with us on countless trips into the mountains hunting both deer and varmints. And it also been along on hunts in the sage covered plains of Wyoming. My experience shooting this suppressor has been pretty uniform over the years.

Shooting The SilencerCo Omega 300

A good portion of my shooting with the Omega 300 has been done using the Desert Tech SRS as a host. Various different rifles and calibers that all functioned well with the Omega at the muzzle. Additionally, we’ve used it on various other bolt action rifles chambered in 308 Winchester, 6.5 Creedmoor, and .223 Remington.

The Omega 300 can be used with or without the Anchor Brake installed up front. I found the brake to be effective in reducing recoil felt by the shooter. Even better than some other cans with brakes built into the muzzle.

silencerco, omega 300, suppressor, cva cascade, 6.5 creedmoor, rifle, shooting rifle supported by bipod on a shooting mat,

For a semi-automatic hosts we’ve shot the Omega using a Desert Tech WLVRN. This multi-caliber rifle would make another great host with its 5.56 and 6ARC barrels. The Omega was easily fitted to either barrel by swapping out the hub from 5/8-24 to 1/2-28. And to add some sport to the outing, I also mounted up the Armasight Contractor 320 thermal scope. Chasing some local coyotes in the dark would be a perfect use for the Omega.

Sound Suppression

The Omega does a great job of suppressing the report of .30-caliber and smaller rifles. With 308 sized rifles the sound and recoil was modest and very pleasant. Even smaller cartridges like the 6.5 Creedmoor, 6 ARC and .223 Remington were even more mild. I expect with the smaller cartridges I would have preferred to remove the brake from the can. As the recoil was minimal, and the slight disturbance of dirt on the ground was just enough to make it annoying.

Recoil Reduction

The large anchor brake that comes with the Omega 300 does a great job of reducing recoil. Suppressors in general reduce recoil already, but the added brake seems to help even more. When shooting the Omega 300 alongside an identical rifle outfitted with the SilencerCo Scythe Ti we could all feel the reduced recoil from the Omega.

But because of the modularity of the Omega, you needn’t use the brake if you don’t want to. Replacing it with one of the Bravo muzzle caps removed the brake, and I think makes it a touch quieter too. If you are shooting one of those calibers that doesn’t have heavy recoil in the first place, perhaps the Bravo cap is the way to go.

Modularity

SilencerCo’s Omega was at the beginning of the hub craze. With so many mounting options you can connect it to your host rifle however you wish. Whether it be a direct thread hub, or one of the locking QD brake options. I used it with both SilencerCo’s ASR locking mount, as well as with YHM’s Phantom QD muzzle devices.

All this can be done using the included tool set that comes with the Omega. It comes with the basic 5/8-24 direct thread mount, so any other options you wish to use would have to be purchased separately.

Value Proposition

With an MSRP around $700, the Omega 300 is an easy choice. These days there are so many options out there with prices jumping all the time. It’s very refreshing to see the good ol’ Omega 300 still available for prices that remind me of the good old days.

Silence Everything with the CMMG Zeroed 36 Suppressor

March 23, 2026Product review, suppressorscmmg, silencer, suppressor, zeroed, zeroed 36coldboremiracle

Introduction

CMMG has been upping their game since I first heard about them years ago, the brand is famous for AR-styled rifles, and has developed various improvements on the design with their Dissent and Banshee models. But having just finished up SHOT Show 2026, one of the biggest themes of the show is that EVERYBODY seems to be jumping in on the suppressor game. And I find no fault in CMMG for joining in on the trend, which brings us to today’s subject. We will be taking a look at the new CMMG Zeroed 36 Suppressor. A full-auto rated 35 caliber suppressor for use with cartridges like 9mm 308 Winchester and 8.6Blk.

The CMMG Zeroed 36 Suppressor

With so many interesting and diverse caliber offerings, it came as no surprise that CMMG started out with a broad selection of suppressor options. From rimfire suppressors made for 22’s, and 5.56 suppressors for your carbine. Up to big 30 caliber cans made to run on their 308 rifles, and even into the 36 and 46 caliber cans for those big bores. Our Zeroed 36 suppressor today is perfectly fitted for a host chambered in nearly any of today’s popular carbine calibers.

The Zeroed 36 uses the very popular hub-mounting system that most manufacturers are moving to. I can’t explain how much I appreciate this trend. As one who is used to having firearms rethreaded in order to use with my suppressors, its beautiful to not have that concern moving forward. The Zeroed 36 came with both a 1/2-28 and 5/8-24 thread cap for mounting to various firearms.

All Zeroed suppressors feature laser welded 17-4 stainless steel. You can feel when you pick these up that they are built robust, which is why it weighs over 17 ounces. Recommended full-auto use suggests breaks every 240 rounds or so. Its hub mounted design is accented by a 3/8 square drive hole in the muzzle-end of the suppressor, which allows you a solid disassembly option. Keeping with its modular design, no special tools are required for assembly or disassembly.

Shooting with the CMMG Zeroed 36

My first test with the Zeroed 36 was an indoor range, testing how it performed with 11.5-inch 300Blk and 5.56 semi-auto carbine. For that I used a Desert Tech WLVRN bullpup, switching quickly between to two calibers in the same rifle.

I also wanted to see how the Zeroed 36 would perform on bolt-action rifles. So, I would end up using it on several, my Desert Tech SRS in 6GT, and 8.6Blk. And I also brought along my Howa Mini and Taurus Expedition, chambered in 6ARC and 308 Winchester.

Shooting across all these host rifles, I used a variety of hubs to get the right thread pitch to fit each one. I even used my Breek Arms Tri-Lug mount, which makes a quick job of attaching and removal of the suppressor.

Modular Mounting

Making the Zeroed 36 a hub-compatible suppressor means there are countless ways to mount it. The can came with two direct-thread hub mounts, threaded 5/8-24 and 1/2-28 which will fit most firearms. I already had several other hub mounts already that I would also use. For shooting my Desert Tech SRS in 8.6Blk I would need a 3/4-24 threaded hub, I used a SilencerCo hub and it fit perfectly. Additionally I used my Breek-LOC QD tri-lug mount, which makes adding or removing the suppressor quick, sturdy and secure. The Zeroed 36 has a 3/8 square drive in the muzzle to give you a robust torque point for changing the hub system.

In total I ended up mounting the CMMG Zeroed to quite a variety of host firearms. A Desert Tech WLVRN SBR with 11.5-inch barrels in both 5.56 and 300Blk, and another WLVRN with 20-inch barrels chambered in 6 ARC and 5.56. To see how it did with 8.6Blk I fit the Zeroed 36 to my Desert Tech SRS A1 where it sounded great. For 308 I ran the suppressor on my Taurus Expedition 308 Winchester, a bolt-action featuring an 18-inch barrel. For 6.5 Creedmoor I installed the Zeroed can on a Bergara 22-inch HMR carbon.

Sound

Shooting a variety of firearms with the Zeroed 36 gave plenty of opportunity to evaluate its sound suppression. As you might imagine, it worked very well with low gas volume cartridges with big bores. When shooting the 9mm and 8.6Blk the Zeroed 36 can had more than enough volume to suppress the expulsion of gas to a reasonable level. Higher pressure cartridges like the 308 Winchester and .223 Remington gave the can a little more of a workout. Even so, the noise at the shooters ear was what I would consider hearing safe. Obviously according to authorities on the subject, you should always wear ear-protection, but the whole reason I own suppressors is to avoid that inconvenience.

Bolt-action rifles were perfectly suppressed by the Zeroed 36 can, whereas some of the semi-auto rifles were a touch louder. For example, using a Zeroed 556 can would have likely given better results when shooting 5.56 rounds. The larger muzzle of the 36 is less restrictive for the tighter column of pressure. And as usual, having a semi-auto ejection port near your face also brings the noise closer to your ears.

My overall impression with the report of the Zeroed 36 suppressor was good. It’s hard to make a modular suppressor that is perfect at everything, there always seems to be one compromise or another. I think this suppressor does a great job of offering the user options for various hosts and calibers. In the open country where I shoot it sounds fantastic.

Gas Blowback?

In our modern suppressor market, we are spoiled for choice. There are so many manufacturers, designs, and features you can get nearly anything you want. A very popular topic when it comes to suppressing semi-autos is the topic of gas blow-back. Semi-autos tend to push exhaust from the chamber back towards the shooter when suppressed. Many suppressor manufacturers have worked to reduce this back pressure to enhance your shooting experience with their suppressor. I shoot outside mainly, and my typical shot string isn’t particularly long. So this is not as big a deal for me, and I found the back-pressure caused by the Zeroed 36 to be acceptable. Some folks seem to be much more susceptible to blowback, and they might want to spend more money on something different.

This is obviously greatly dependent on the host firearm, for example shooting the Zeroed 36 on my bullpup rifles brings the ejection port even closer to your face than conventional rifles. It doesn’t bother me as I prefer the advantages of the design, but I can see how it might bother others.

For shooting the Zeroed 36 suppressor on a pistol, I chose my Ruger RXM 9mm. After installing a booster and piston into the back of the Zeroed can, it threaded nicely onto the pistol. It was a bit heavy for a pistol suppressor, but it worked great at keeping down the noise. There was of course a little added backpressure, but that is not uncommon.

Optimizing AR-15 Accuracy for Long-Range Varmint Hunting

March 20, 2026blogaccuracy, ar-15, ar15, long-range, varmint huntingcoldboremiracle

Written by Guest

Intro

Stretching an AR-15 past 300 yards on prairie dogs this spring sounds ambitious. True — but not crazy. The platform has come so far that varmint hunting at real long range is practical now, not just some YouTube fantasy.
Still, you can’t bolt a Vortex onto a stock Ruger AR-556 and expect half-MOA groups at 400 yards. Doesn’t work like that. Every component matters — barrel, trigger, optic, ammo. Let’s see what actually moves the needle when you’re building an AR for precision small game work at distance.

What You Need to Know About the AR-15 Rifle

The AR-15 is not a single rifle. It’s a system — and that distinction matters way more for precision shooting than people realize. So, you need to know how the AR-15 rifle works to make the most of it for varmint shooting.
Here’s where most guys go wrong first. Factory AR-15s ship with mil-spec triggers breaking at 6-8 pounds. Heavy. Gritty. Completely wrong for careful shot placement at range. Drop in a Geissele SSA-E or a LaRue MBT-2S, and you’ll wonder why you waited. Cheapest meaningful upgrade you can make.

Next up — the handguard. Free-floated rail, non-negotiable. When your barrel touches the handguard anywhere, harmonics go sideways, and groups open up. Aero Precision and Midwest Industries both sell solid free-float setups. Now, something people overlook: the AR-15’s direct impingement gas system actually helps accuracy. Sure, gas pistons — like on an HK MR556 — cut fouling. Yet DI vents gas straight through the bolt carrier, meaning less mechanical movement while the round fires. For varmint hunting specifically, where you shoot from stable positions at tiny targets, that consistency edge compounds over an afternoon. Finally, modularity. No other platform lets you swap uppers in thirty seconds — .223 coyote rig to a 6.5 Grendel setup. That flexibility is why the AR owns this space.

Caliber Selection for Long-Range Varmint Work

Caliber choice will make or break you out past 300. Period. Under 300 yards, .223 Remington handles prairie dogs and groundhogs just fine. Cheap, low-recoil, available at every Walmart in America. Beyond that, though… The round bleeds velocity fast, and wind drift gets ugly with lightweight 55-grain pills.

223, 223 remington, hornady, bullets, handloading, reloading,

So what do you actually run? The .224 Valkyrie deserves a serious look. Federal built it for long-range AR work, and the 90-grain Sierra MatchKing load stays supersonic past 1,000 yards.
Overkill for ground squirrels at 500? Maybe. But that flat trajectory makes first-round connections on small targets way easier. Meanwhile, 6.5 Grendel gives you heavier bullets with strong ballistic coefficients — plus enough thump to drop coyotes cleanly.
Also worth knowing — barrel life varies across these calibers. The .224 Valkyrie eats barrels faster than Grendel, noticeably quicker than .223. Naturally, if you’re doing high-volume prairie dog shoots — 200 rounds in one sitting — factor that in before committing to a caliber.

Barrel Upgrades That Actually Matter

Not every barrel upgrade is worth your money. Some are. Knowing the difference saves you hundreds of dollars and a lot of frustration. Start with barrel length. For most varmint calibers, 18 to 20 inches hits the sweet spot between velocity and portability. Go shorter, and you leave real fps on the table. Conversely, past 20 inches with .223, diminishing returns kick in, and you’re hauling dead weight.

Twist rate matters too — more than most shooters realize. A 1:8 twist covers the widest range of bullet weights in .223. However, heavy-for-caliber stuff in .224 Valkyrie needs 1:6.5 or 1:7 to keep those long 90-grain bullets stable. Criterion and Bartlein both make outstanding aftermarket options.
On material — stainless steel beats chrome-moly for pure accuracy. The tradeoff is durability; chrome-moly holds up longer under sustained fire. For varmint hunting, where precision matters more than barrel life in tens of thousands of rounds, go stainless.

Optics and Scope Setup

Glass matters more than the rifle itself. Yeah — hot take. Still true. For work past 300 yards, grab a variable-power scope in the 4-16x or 6-24x range. The Vortex Viper PST Gen II and Athlon Ares BTR both deliver without requiring a second mortgage. At those distances, though, magnification alone does not cut it — you need turrets that track and repeat.

ar15, ar 15, 6.5 Grendel, us optics, FDN17X, — this 6.5 Grendel rifle was unstoppable with the **US Optics FDN17X** on it

First focal plane holds the edge because your reticle scales with magnification, keeping holdover marks accurate at every power setting. The second focal plane works too — but only if you dial a set magnification before using subtensions. Otherwise? Your holds are off. MOA or MRAD — pick one, learn it properly. In practice, MRAD pairs better with metric-based ballistic calculators, and most competitive long-range guys have gone that direction already. Yet
plenty of accurate shooters run MOA without a single issue.

Besides parallax adjustment — don’t sleep on it. Past 400 yards, even a slight parallax error shifts your impact enough to miss a prairie dog entirely. Accordingly, check that your scope’s parallax knob dials low enough. Some budget glass bottoms out at 50 yards, which is useless for this kind of work.

Fine-Tuning Ammunition and Loads

Everything upstream — barrel, trigger, optic — only hits its potential when the right ammo feeds through it. Before you touch a reloading press, try factory match loads. Hornady V-MAX and Federal Premium’s Nosler Ballistic Tip offerings are proven. Test at least three loads in your specific rifle. Seriously — two guns off the same line can prefer completely different ammo. That’s barrels being barrels. Essentially, no two are identical. Handloading takes things further, though. Consistent charges weighed on a digital scale (not thrown volumetrically), proper brass prep, and careful seating depth work can shrink a 1-MOA rifle to half-MOA. Specifically, the Redding Type-S bushing die set earns every penny if you’re chasing sub-MOA consistency.
Brass lot consistency gets overlooked constantly. Mixing cases from different production runs introduces volume variations that change pressure and velocity shot to shot. Consequently, even a 15 fps spread shows on paper at 400 yards. Therefore, keep your brass sorted by lot number — no exceptions, no shortcuts.

ar15, quattro 15, desert tech, eotech, vudu, LPVO, desert shooting,

The Bottom Line

Building a precision AR isn’t about buying the most expensive parts. Your job here is to make the right parts work together. Get the right trigger, barrel, optic, and ammo, and 400-yard prairie dogs become routine. And you won’t need a $4,000 custom build, either. Smart upgrades for varmint hunting in the right order are what you should focus on — not throwing money at cool stuff from r/longrange.

Vortex Optics Defender CCW Enclosed Solar Micro red dot

March 18, 2026Optics, Product reviewccw, defender, micro, Red dot, rmsc, solar, Vortex, vortex opticswcoldboremiracle

Prologue

Enclosed red dot sights are becoming more and more popular, and I decided recently that I’d jump into them with eyes open. Today we are taking a look at the Vortex Optics Defender CCW enclosed solar micro red dot. Part of the larger Vortex Defender family, this model encloses the emitter and adds a solar power supply all in a micro red dot that drops onto the popular RMSc footprint. We’ll review this sight and give you some feedback on it and how it stands next to its competition.

the Defender CCW was a perfect fit for my Girsan 2311

The Vortex Defender CCW

I’ve had a couple other Vortex Defenders recently, and I quite liked them if I’m honest. So it was with some confidence that I decided to match this new Defender with my latest 2011 style pistol. My Girsan Witness 2311 has an RMSc footprint machined into it’s slide, so I wanted to put a good enclosed sight on the pistol, which led me to the Defender.

The Defender CCW Enclosed Solar Micro Red Dot (ESMRD) is a tough built dual-powered sight. It’s large window houses a configurable reticle inside its protected weatherproof housing. This dot is made to fit large weapons down to sub-compact handguns.

Like other Defender dots, this one came with an incredible selection of accessories. A great variety of mounting screws in various sizes, an one-degree angle shim, mounting and adjusting tools. As well as a picatinny mount, and a cute little rubber cover.

Mounting the Defender

After removing the sight from my pistol, I sat down to mount the Defender ESMRD. Using a set of screws that came with it, I did a few test fits to ensure it would be properly secured. I always like to put a touch of blue Loctite on the threads and under the screw-head. Nothing worse than your red dot coming loose while shooting, so I snugged it down nicely with the included tool. I love that Vortex red dots come with basically everything you need to mount them.

Powering up the Defender would require removing the battery cover to remove the battery isolation sticker. After which the reticle lit up and allowed me to give it a rough adjustment before heading to the range.

Range-time and Zeroing

Zeroing the Defender was easy, lining up the reticle with the sights as I torqued it down. After that, with a few shots I made some adjustments with the included tools. In no time the Witness 2311 was hitting my point of aim.

We would shoot quite a bit at an indoor range the first time. Getting a good feel for picking up the reticle and focusing on targets. Following the instructions I cycled through the three reticle configurations, this is done by pressing the + and – button together. You can select between a 3 MOA dot, a 32 MOA circle, or the two together. I am a bit of a circle dot kinda guy so that where it typically stayed.

You can also lock out the buttons to prevent unintended adjustments. Pushing the + button and holding down until the reticle blinks, and easily reversed by doing the same process till it blinks twice.

According to the manufacturer, the Defender Solar Micro will last approximately 35,000 hours on a battery, using the 3 MOA dot with no solar input. That might be the case, but I wasn’t going to find out. As I like the circle dot configuration, and there would certainly be some solar input since I usually shoot in the daylight. But furthermore I was going to engage the auto-shutdown feature that is a must for red dots these days. By holding both buttons down you can engage or disengage this feature.

Optical Performance

While I am not a huge fan of the “mailbox look” , this red dot is a bit larger than other options because it is an enclosed emitter. Its very comparable to other enclosed emitters of the same size, and has a large window. For a micro red dot It certainly felt like a big lens.

Girsan, witness 2311, 9mm, eaa, 2011, vortex, vortex optics, defender CCW, enclosed, red dot,

I did feel like the Defender CCW Solar Micro had less color change when looking through it. And I also really liked how sharp and clean the reticle looked. No parallax made it easy to focus on whatever I wanted to shoot.

Usability

Adjustments and controls of this Defender were easy to understand and remember. Its included tools made it easy to zero the reticle and the included directions explained everything nicely. I like the dual power source, and the battery is easy to change without removing the unit from the host. I also like that they used the CR2023 battery which is more common than the other options typically used in micro sized red dots.

Value

MSRP on this red dot from Vortex’s website shows $400, but as usual you can find this red dot on places like Optics Planet for much less. I have other similar red dots that retail for more that I don’t like as much as this Defender. Even if you broaden the search to other larger red dots of different footprints, I still think this one offers more for less.

Pros and Cons

First off, this thing is handsome. And we can’t pretend that doesn’t matter, it looks like a great quality fit for nice handguns. The controls are easy and comprehensive, external battery mounting and the plethora of included accessories and mounting options make it a slam dunk. Its big clear window makes for quick finding and engaging of targets, and the reticle selection is a big plus. All this for a reasonable price when compared to others.

If there was anything I would change about this red dot, it would probably be a bigger circle option. Nothing wrong with the 32MOA, but I wouldn’t mind like a 50 or 60 MOA circle option too. But of course these are subjective preferences. I also wouldn’t mind if they incorporated a notch on the base to double as a rear sight if needed.

Concluding Thoughts

Every time I get a new Vortex red dot, my inventory of fasteners and tools is enriched. Vortex packs some great added value with their red dots, and that’s a pretty big feather in the cap for this sight. My selection of Defenders continues to grow, and this one is probably my favorite so far. The simple controls and all the options are what seal the deal for me. I am uninterested in red dots moving forward that don’t have auto-shutdown, this and other features make the Defender CCW Solar Micro very adaptable to various applications. I look forward to the bright future and reticle with this combination.
