US Optics SXR 1-6 LPVO

October 9, 2025Uncategorized1-6x24, lpvo, riflescope, scope, sxr, us optics, USOcoldboremiracle

Introduction

I have grown quite fond of low power variable optics (LPVO’s), and they have worked their way into my gun collection nicely. Today I am taking a fresh look at a relatively new LPVO from US Optics, it’s called the US Optics SXR 1-6. I have had several US Optics LPVO’s over the years and have been very happy with them, you can read about the TS Series of LPVO’s here. But today its more about the new stuff, and the newest line of scopes from US Optics is the X-Series of scopes. The SXR 1-6 is the smallest member of that family, but does this scope punch above its weight?

US Optics SXR 1-6

Upon inspecting the US Optics SXR I was very pleased with its presentation. The scope is available in either a second focal plane option or a first focal plane. The option we are testing today is the FFP version, with the SRM MRAD reticle. I like this version a little more than the other alternative as I’m not a big horseshoe reticle kinda guy.

The first thing to stand out to me was the robust 34mm tube which is bigger than most LPVO’s. Typically I prefer 34mm tubed scopes, but for LPVO’s I am still deciding if I prefer them over 30mm. The larger 28mm objective lens certainly does offer more collection of imagery.

With capped turrets you can use the reticle of the SXR to hold over for any distant shooting. Though the turrets do appear to be quite useful uncapped as well. The finger adjustable turrets are 1/10 MRAD per click, and have a total of 10 MRAD per rotation. This is great on many scopes, so I found it particularly welcome on this little scope.

Adjusting the power magnification is done at the rear, I was glad that US Optics had incorporated a removeable throw lever to the magnification ring as well. This makes it easy to blindly grab for and adjust your scope in a quick shooting scenario.

Specifications

Magnification:	1-6X
Focal Plane:	First Focal Plane (BDR5556, SRM) \| SFP (SFP MIL)
Eye Relief:	3.5 in
FOV @ 1x:	119.16ft @ 100y

For mounting the SXR to a rifle, I used the ZRO Delta 34mm cantilever mount. This would make it easy to mount on most rifles with the proper amount of eye relief. The first rifle I would mount the scope to would be my Desert Tech WLVRN chambered in .223. It was a great companion for this rifle, as it does very well at short and medium ranges.

On the Range

My first trip to the range was to zero the SXR on my WLVRN. I zeroed the rifle at 100 yards, which was quite easy using the finger adjustable turrets. After confirming a good zero, I set to zeroing the turret. This was easily done using a coin to loosen the turret cap, then setting the turret to zero and reinstalling the cap.

After zeroing the scope, I did some additional shooting at both 100 and 200 yards using the reticle to hold over. I found the reticle to be perfectly serviceable for precise shooting within the limits of the six power magnification. And at lower magnification particularly with the reticle illuminated it gave a great field of view. Bracketing targets in red made shooting fast up close.

Quality

This is the highest quality US Optics LPVO I’ve used, at least recently, it reminds me of the old SN and SR scopes they made. The optics are top notch, giving and incredibly clear picture at all power settings. The sharp reticle is great for hold overs, and isn’t overbearing for a short range optic.
The Turrets are also fantastic, whether you choose to run them exposed or cap them. They feel very tactile, and you can hear each click. they are also low profile to keep them from snagging on everything.

Durability

While I believe durability is best tested over the course of a year or so, I feel this scope is very robust in structure. And based on my experience with other similar scopes from US Optics, I expect it will stand up to my typical routine. Switching the scope from rifle to rifle, and mount to mount. Be sure to follow along, as I will update this article in the future with additional feedback on durability.

Value

In a market flooded with LPVO scopes, it might be hard to stand out. The under $500 market is packed, and there are plenty of good options. The $500-$1000 market is a little more competitive, and the SXR is on the lower end of that spectrum.

The US Optics SXR 1-6 is in good company, comparing to other brands like Eotech and Trijicon. And available for less depending on where you buy it, of course if you use my %15 promo code shown here you can get the best price.

My Summation

Having spent some time shooting with the SXR scope, I have become quite a fan. It is a big step up over previous LPVO’s in the TS line from US Optics, and it gives users a high quality product for a good price. The large lenses give fantastic clarity and high definition of targets and their surroundings. The overbuilt turrets are great for dialing if you choose to use them so. The SXR SRM reticle is a great dual-use reticle, it can be used for fast target bracketing up close or for more precise work. Using its graduations allows you to make accurate holdovers and corrections should you use the scope for precision shooting.

I am a big fan of 34mm tubes, especially on precision optics. It makes sense that for some folks the 34mm tube may be a bit much, and adds both bulk and weight. But so far it hasn’t bothered me at all.

Little add-ons like the built-in throw lever and the easy to adjust turrets add more value and usability to the scope. It may be a step up in cost, but I think the scope punches above its weight. And it compares well to scopes that cost more. I would love to see another variant of the SXR in a 1-10 with adjustable parallax.

The US Optics Foundation FDN 25X

August 1, 2020Optics, Product review25x, 5-25, fdn25x, foundation, foundation 25x, us optics, USOcoldboremiracle

Introduction

Many years ago, when I first stumbled down this rifled rabbit hole. I would daydream about the high-end and prestigious rifles I saw in magazines and movies. The internet had not yet become the superhighway it was destined to be. But as it developed I could also visit websites and court those beautiful works of art. Not only was it the rifles, but the impressive optical sights that accompanied them. My dreams of owning such a piece of artisanship seemed unattainable at the time, but I never could have foreseen just how far down this hole I would go. Today we are looking at the US Optics Foundation FDN 25X.

Years would pass, more than a decade. Before I found myself the proud owner of what I had always considered a dream scope. US Optics had always been one of the brands I was smitten with. Maybe it was the incredibly robust design that seemed overbuilt for what many would consider standard use. On top of their strength, US Optics scopes had a mechanical attractive flair. It was like looking at top-fuel race engine, you could see all the little things that made it work its magic, and that enticed me even further.

The US Optics Foundation 25X

That first US Optics scope was an ER-25, it was the first but far from the last. I’ve since had four more. With the latest being the newest offering from US Optics, the Foundation Series 25X. The Foundation series is USO’s latest line of top tier telescopic sights, made here in the US. The FDN25X boasts some impressive features. Some you would expect, and others you might miss if you didn’t pay close attention.

The 25X uses a fairly standard 34mm tube and 52mm objective, manufactured from 6061 T6 aluminum, it shares a nearly identical body with its predecessor the B25. But there is more, the FDN25X has the new EREK3 elevation turret with 11 MRAD per revolution. As well as a 180-degree throw magnification ring, the new JVCR reticle (my favorite) with illumination available in red, blue, or green, smooth parallax adjustment, and an internal bubble level.

Unboxing

As I opened the box of the 25X and first picked it up, I was surprised at the weight. At thirty-four and a half ounces, it’s not exactly light but it seemed light for its size. Perhaps I was expecting it to weigh more. I surely wasn’t going to waste much time, I wanted to get this scope mounted and get shooting with it.

In no time I mounted it on the rifle it was ordered for, my custom built 257 Blackjack. It is a lightweight carbon fiber hunting rifle to haul all over these Rocky Mountains for Mule Deer, Elk, and likely a few Antelope as well. The 25X makes a great companion optic for the Blackjack. It stays supersonic beyond two thousand yards, and its energy, drop, and wind deflection makes it ideal for long-range shooting. The 25X has been designed and built for just such shooting. With high-quality lenses to give a clear picture of distant targets. The JVCR reticle gives fine wind holds and holdovers, with .1, .2, and .5 subtensions.

Rangetime with the FDN25X

So with the 25X mounted in rings on a 20 MOA scope base, I wandered off into the hills to get it zeroed and to put it to the test. Zeroing the scope was simple, the new EREK3 elevation turret was easy to figure out with a brief revision of the manual. I removed the center screw on top of the turret and adjusted my reticle with the provided hex wrench. After a couple adjustments, it was zeroed perfectly and my elevation set to zero.

Normally I slowly work my way out from closer targets to more distant ones, but that day, I went straight for the long shots. The first shots after zero were 1230 yards, I dialed 6.5 MRAD on the EREK3, and fired a few shots. After getting the wind call right, they were hammering the steel. The EREK3 turret is a good combination of stiff, and crisp. Not too hard to turn, but firm enough to avoid accidental movement.

As it happens, my first trip out with the FDN25X was a shoot with Donald Trump Jr. He was impressed by performance of the 257 Blackjack, and the FDN25X

Turret clicks are both audible and tactile, adjustments are easily made from the shooting position by simply counting the clicks either felt or heard. The magnification ring is also a welcome improvement, with only 180 degrees of rotation, you can go from 5x all the way up to 25x with one movement. Instead of having to release and turn again like other scopes. It’ also easier to turn than previous models.

Refinement

After zeroing my scope, I swapped out the scope base for a 30MOA, to get the scope closer to an internal mechanical zero (to avoid the extremities of erector movement). And with it freshly zeroed, the turret had a full twenty-one MRAD of elevation available. It is highly unlikely I will ever use that much elevation, according to my ballistic computer, twenty-one MRAD will take the supersonic Blackjack to 2159 yards.

The EREK3 elevation, and US #1 windage turrets

US Optics’ JVCR reticle is one of my favorite reticles, I’ve got another one in another US Optics scope. The .2 MRAD marks are all over the reticle, giving a quick and easy reference for adjustments. An open center floating dot makes a perfect reference point when trying to shoot tiny groups on paper. And the open space around it will make it easy to hold center on any of the animals I plan on hunting this fall.

I ordered green illumination on the scope. Mainly because I’ve had red on every other scope I’ve ever had and wanted to see something different. I’m not overly worried about it, as illumination has rarely been used in most hunting scenarios I’ve been in. But for that occasional need, it is sure nice to have.

One little thing that I found that did bug me perhaps, is an abnormal crescent shaped shadow when the scope is dialed to either of its extremities. This is normal as US Optics has it listed under their FAQ’s on their website. To be fair, it is only visible at low power (less than 8x), and only when the EREK3 turret is almost all the way up or down. I think it is very unlikely that it will ever be an issue. Because if Im dialed all the way up, I’ll very likely be zoomed in at least to 12x or more. And if it is an issue bottoming out the scope, then you’ll need to use an additionally canted base. Like I said, a small issue, but one you may want to know about.

Beneficial features

The anti-cant bubble inside. When looking thru the scope and focusing on the target, the highlight of the bubble is seen at the bottom of the reticle

Another very cool feature of the Foundation 25X is the internal level or anti-cant device as it’s often called. I always loved the idea of having it inside the scope, but so many times its been done poorly. Not that I have anything against it being external, especially good ones you can see from the shooting position.

But it is so much nicer to see in real-time, through your aiming eye without taking it off the target. The way US Optics executed this level is very nice, I ordered the internal level. But it is so subtle that I didn’t even notice it the first time I looked through it. It is tucked neatly at the bottom of the field of view, and like I said, its so low profile that you actually have to make an effort to see it. I’m not sure if the engineers at USO want you to look at the actual bubble itself. Or if you are meant to see the highlight reflecting on the bubble as your reference point, either way, it is very handy when you’re in the shooting position.

Accuracy Testing

I also tested the scope for actual click value, which can vary greatly in rifle scopes. I tested the click value by measuring the turret movements against the values of the reticle, as well as against a ruler at a set distance. By doing this you can tell if the clicks actually represent the value claimed. I’ve never tested one that came out perfect, but this one is close enough for my purposes. Under 10 MRAD of adjustment, the actual value was no more than .02 MRAD off of claimed value. And at 20 MRAD, it was just over a tenth MRAD from claimed value. I am not a rocket surgeon, but I think it’s safe to assume that the difference between claimed and actual is spread progressively across the curve as elevation increases.
In addition to testing click value, while I had the scope clamped down solid I also checked the tracking and for reticle cant. Cranking the turrets up down and left and right shew no inconsistency. They always returned back to the exact same spot as I counted the clicks. No noticeable movement in the reticle either, as I zoomed from one magnification to another.

Final thoughts

The only thing I haven’t been able to test so far with the Foundation 25X, is its durability over time. My First US Optics scope took such a beating I was sure it would break, banging into rocks, falling off the tailgate onto concrete attached to a twenty-pound rifle, stuff like that. But I was blown away when not only did it survive these events, but didn’t even lose zero. That is a pretty hefty standard to live up to, and I hope that the Foundation scopes are up to it. Time will tell, I certainly don’t plan on dropping it, or bashing it against rocks, but who knows what the future holds?

There is no way this rifle and scope aren’t coming with me for hunting season this year. The 257 Blackjack will light up anything I intend to hunt. And coupled with the impressive view from the Foundation 25X, it should be unstoppable. I am extremely anxious to get up into the high country, and get comfortable and effective with this rifle and scope. You will no doubt be hearing from and seeing more pictures of us in the fall.

US Optics TS8X

July 29, 2020Optics, Product reviewLvpo, Optics, scope, ts, ts8x, us optics, USOcoldboremiracle

Low Power Variable Optics (LVPO’s) have been flooding through the firearm market for years now, likely due to the proliferation of medium-range carbines. It didn’t take long for shooters to realize the value of variable low power optics, but what makes an LVPO shine over another?

I’ve had several different models from a wide range of manufacturers, and today we will discuss in depth the US Optics TS8X.

The Tactical Sport 8 power LVPO is one of several great scopes I’ve been able to shoot in the offshore line of scopes from USO. So far they have proven to be a great option for shooters in my opinion. I have been shooting USO scopes for many years now, and to be completely honest I was a bit worried when I saw they were releasing a more affordable line of scopes. My concerns were quality and performance, for which USO’s are well known. My concerns were assuaged with the TS20x, which quickly became one of my favorites. The TS8X has so far been just as good an experience.

Why an LVPO?
I also have the TS6X, which is the little brother to the TS8x. I wanted the 8X because having used several 1-4’s and 1-6’s, I wanted just a little bit more power for seeing those downrange targets. Again in my opinion, a 1-8 or 1-10 is about perfect for a medium range rifle, for distances around six to eight hundred yards. The TS8X fit that spot perfectly in my estimation, and with the RBR Reticle, it would give me plenty of holdover points for shooting at those further distances.

Features
The TS8X features a 30mm tube, with adjustable diopter eyepiece, covered turrets, and an illuminated front focal plane reticle.
Many manufacturers have moved to the 30 or 34mm scope tube now, it gives a larger tube to pass light through, as well as allow a larger erector to increase the internal mechanical movement of the scope. The parallax is fixed for 100 yards, which leaves the diopter eyepiece focus the only adjustment for the image seen. This is common in most LVPO’s, particularly in this price range. If I had one wish for the TS8 it would be adjustable parallax, I frequently shoot well beyond 500 yards with this scope and others like it. The ability to adjust parallax for those distance targets would be very welcome.
Another feature that thankfully is becoming more commonplace, is the reticle placed in the front focal plane (second focal plane models are also available at a lower cost). This means the reticle is magnified with the power setting of the optic, keeping the reticle values always the same regardless of power setting.

The RBR reticle is illuminated red, with an adjustable rheostat for brightness. It also features both MRAD hash marks (both whole and half) as well as range based holdover points, including wind holds at five and ten MPH.

With the stiff competition in the LVPO market, the TS8X fits in the middle ground of price range. There are many options that are far less in price, and many others that cost double, triple, or more.
My initial concerns about quality were more based on mechanical performance and robust construction. I knew that due to its price point, it would likely not have the same optical quality as scopes costing more, which I was okay with.
Speaking of optical quality, I found the image to be bright, and clean. Not much to complain about there, but don’t expect to see the same image as a $1600-$2400 scope.
I found the RBR reticle to be very useful at distances out to nearly 1000 yards, at 8X it could possibly be a little thick for tiny targets, but I don’t expect many people will be doing benchrest or squirrel hunting at that range. For real world shooting, such as echo targets inside 600 yds, it is perfect. The rifle its currently mounted on will be doing some coyote hunting, and I’m very confident that anything inside 800 yards will be easily identified, targeted, and engaged using the RBR.
As I mentioned above, the reticle features both MRAD marks, as well as estimated drop and wind marks. This is handy, because if you need an honest elevation or wind call, you have the actual MRAD values. Whereas if your shooting at the aforementioned coyote, you can use the drop values according to how far away he is.

I mounted the TS8X on my Desert Tech MDR, which at the time was a sixteen-inch 223. The scope was easily zeroed with no tools, and in no time I was shooting steel all over the range.

The MDRX with the TS8X and **YHM Turbo suppressor**

I love using the scope at 1X, with the reticle lit up, it is just like using a red dot scope. Up close shooting at steel, animals, or whatever else is easily done with both eyes open. Cover the target with red as you break the trigger will give you sure hits.
I then switched out the barrel for the new Hornady 6mm ARC barrel, to see how the TS8X would match up to its ballistic curve.
Without even rezeroing the scope, I was in business, perhaps more a testament to the rifle than the scope. I later made a few corrective adjustments, and the rifle was punching centers very consistently. The click values of the turrets seemed to be close enough to values marked, but to be honest, I hardly had to move them.

Stretching the rifle out would require using the drop points indicated on the RBR reticle, I figured they would be close since the 6 ARC is not too far off of the 223 trajectory it is based on.
It was close enough to be dangerous that is for sure, at 960 yds I shot over the target. The 6 ARC has less drop than a 223 at that distance, so I held a corrected hold (7MRAD) and a bit of left wind for a perfect center punch hit.
I followed it up with a few more shots to confirm, inside I was giggling like a child watching the trace of my bullets on the way to the target.

I’m not sure if its the TS8X or just better optics that we are spoiled with today. When I first started shooting these farther distances, it seemed like 10X was barely enough, and 15-25 was more like what you needed for shooting long range. But I found shooting almost everything inside a kilometer to be relatively easy with the 8X of this little USO.
I recently took a LE Carbine LVPO course and was extremely happy with the way this little scope ran on the range. We engaged targets all over from 50 to 600 yards in every position you can imagine, I was able to use the wind holds to get some great hits on windswept targets boiling in mirage.
I guess the technology is catching up, soon one thousand yards will no longer be a long range benchmark. It will be more like medium range for drills at a beginners carbine class. If you find yourself on that spectrum, the US Optics TS8X will fill the need for a medium range optic. And it will do it without needing a signature loan to checkout, and you’ll still have the quality and guarantee US Optics has always put on their scopes.

US Optics TS20X Rifle Scope

January 28, 2020Optics, Product reviewreview, riflescope, scope, ts20, ts20 review, us optics, us optics ts20 review, USOcoldboremiracle

Introduction

Im a sucker for scopes, you might say I have a weak spot for them. I have used most of the very best scopes, and Ive also used many that weren’t worth straining my eye to focus through them. Part of my affliction is due to being spoiled for some time now, and I blame US Optics for it, at least partially. I have had several of them over the years, and they have earned their keep in my safe. Today I bring you another review of the US Optics TS20X rifle scope.

US Optics has a history for robust builds, with nail driving strength. They have seen many changes over the years, and we could argue surely over the pros and cons. But for me, only one thing matters, whats on-top of my rifle, and how does it perform.

The USO TS20 mounted on my Desert Tech SRS A2

The TS20X

As a riflescope addict, I was interested when US Optics launched their Tactical Sporting line of scopes, the TS Series. Like any true addict I rested not until I had the TS 20 in my hands. It was love at first sight.

My initial impression of the TS 20 was its weight, it seemed light for a USO. This new TS line was clearly a more economical series of scopes, so I expected a simpler construction. Lightweight, and a very clear and clean image were both very welcome features. The JVCR reticle was new to me, and well received. I prefer the newer “Christmas tree” style milling reticles, and I found the JVCR to be very handy to use. The offset two tenth windage holds made perfect sense when hurriedly making a wind call. And like most good reticles, even numbering to keep track of your holds. With as many as ten mils to hold over, and five wide for windage, it makes a perfect companion for todays ultra-flat shooting rifles.

Another feature that impressed me very quickly was the focus/parallax adjustment, which is adjustable down to ten yards. At first I didn’t think it was a big deal, but when I dialed the scope down to 2.5X, I realized that this scope could almost be used like a red-dot. If I ever had any up close shooting to do such as approaching a wounded animal, I could simply turn on the illumination, and mark the target with the red cross and pull the trigger. This to me seemed like a very handy feature for a scope I would surely use while hunting. And yet with the max power of 20X from the scope, there are few things I would not be able to shoot at inside my distance envelope.

US Optics has always helped me put food on the table

The turrets of the TS20 are ten MIL per revolution, that for me is a minimum. Long gone are the days of five MIL per turn scopes, that was so 2010. The clicks are clean, and you can both feel and hear them as you turn the turret. The TS20 has an interesting zero-stop feature, but it requires you to limit the rotation to one turn only. Not a big deal for many things, but since I like to live on the edge, I decided to pull any stops and run it wide open. One complaint if you’ll allow it, the turret housing isn’t numbered to help you keep track of what revolution you are on. Bit of a pet peeve of mine, but not a deal breaker by any stretch. The tension of the turrets, power ring, and focus knob were all just right, not too hard to turn, but stiff enough to avoid accidental movement while packing it around.
I already mentioned the parallax/focus adjustment, but just next to it on the left side of the scope, is the rheostat to adjust the illumination on the JVCR reticle. It’s your standard 1-10 clicks with an off position in between each setting. 10 is bright enough to use as a red-dot in dim daylight, and 1 is dim enough to use with night-vision and thermals.

With 24 useable MILS of elevation from its 34mm tube, the TS20 is a very useful long range tool. The rifle it currently commands only needs 5MRAD of elevation to get to a thousand yards. But even if you are shooting a 308 you wont have a problem getting way out there. But with it’s super low power setting, and 28 ounce weight, it is a good option for a long-range hunting rifle as well.

Shooting with the TS20X

In the field the TS20 performed exactly like every other USO I’ve ever fielded. Click values were consistent, and lined up with my known ballistic data. I keep coming back to it so forgive me, but I love the high and low range of this scope. I never thought I would want a 2X precision rifle optic, but I sure am glad I have one now. In the field was the best place to see the value.
I am not huge on high magnification, I rarely use my scopes above 20X. So the TS20 is right in the middle of where I want all my X’s. Even at max power the image is still clear, and the reticle is very useful. Even so, I usually find my power ring somewhere between 10 and 15. It is at those medium settings that I find the optical magnification and reticle proportions to be ideal, both for targeting, and making corrections.

The USO TS20 played well with everything, especially this clip-on thermal

I mounted the TS20 on three different rifles, first on my Desert Tech SRS A2, and then on my MDR. Regardless of which caliber I was shooting I had every confidence that the TS would keep up. Whether it was hunting varmints on the foothills around my home, or chasing big game like mule deer or elk through these big Rocky Mountains. I’ve never had to worry about my US Optics scopes while traipsing through the brush, and no amount of bumps, drops, or bouncing around in the bed of a truck has ever knocked them out of zero. The heavy recoil from my 300 Remington Ultra Mag didn’t phase the scope, and neither did the repetitive cycling of my 450 Bushmaster chambered Desert Tech MDRX, it just kept on ticking.

Final Thoughts

The Tactical Sporting Series of scopes from US Optics looks like it has a bright future. The scopes are well made, and fit a price point that opens the door to a less expensive market than historically available to those wanting US Optics products. The premium Foundation Series remains the flagship of US Optics quality, I may need to get one of those too, but for now I will enjoy the view from this little TS20.

US Optics B25

August 13, 2018blog, Optics, Product reviewb25, scope, us optics, USOcoldboremiracle

Introduction

The craziness of youth has somewhat subsided in me, I used to haul all kinds of garbage with me all over the mountains. To some degree I still do, but the wisdom that comes with age has also taught me when to say enough. There was a time when I would carry in my pack a days worth of snacks, water, lots of ammo, shooting mat, tools and who knows how many other things. All this for a quick couple-hour hike around the steep Rocky Mountains that tower over the valley I call home, the Scout motto was never lost on me. Perhaps it was experience that assuaged the contents of my backpack, maybe it was the tired back and legs that carried all my gear that convinced me to lighten up. But like it always does, it seems that technology has snuck in and played a big part in lightening the load. Good gear tends to be heavy, light good gear tends to be expensive, today I want to discuss how I have applied all this to my backcountry recreating. Today I bring you a review of the US Optics B25 rifle scope.

Many of you may remember that for quite some time I carried a US Optics ER-25 scope, it was a spectacular optic. It carried almost every option I could have dreamed up when I first got into this business, and it was tougher than I could have ever imagined. US Optics scopes are famous for their robust construction, and they stand up to abuse that would make a safe queen owner toss their lunch. Hardly a gimmick, I can attest that my USO took several spills, many of which I thought for sure would end up costing me money, a trip back to the factory, and some serious downtime. But to my surprise and delight, my scope never lost zero, or required re calibration. Even falling onto concrete mounted to a twenty pound rifle landing on the scope itself wasn’t enough to damage the scope beyond a few dings.

A young buck seen through the B25 and Gen2 XR Reticle

With experience like that, countless trips into the wild, constantly dialing and working the scope, you might imagine my discomposure when I first saw and lusted over US Optics new line of scopes. The B series of scopes have what I would consider smooth and more modern lines, I know that some people don’t care about looks, but I am a sucker for performance when it meets precision and beauty. When I first got my hands on one, I couldn’t help but be impressed. Clean and bright were the images I saw through the glass, and the always ample selection of reticles leaves no excuse to even the pickiest of reticle snobs. Simple and strong turrets, with improved features like locks, and a quick tooless rezero for the elevation only increased my desire to run these scopes through the paces of my alpine shooting adventures. But one of the significant improvements of the B series of scope was the weight. The robustness of US Optics scopes has always translated into significant weight, something I was okay with because I knew it going in. The B 25 weighs six ounces less than my old ER 25, yet boasts all these improvements. The scope may feel light because I’m used to something heavier, but it sure felt like a bonus to me.

Giving up weight isn’t a bad thing, as long as you don’t loose the benefits of strength and durability. Which the B25 certainly seems to have retained. I still wouldn’t say I am anywhere near having a lightweight rig, but it still goes with me everywhere. Reducing the weight certainly helps, but having what some might call excessive scope can pay huge dividends in these mountains. Glassing a nice buck from a mile away usually requires a spotting scope, and a good one too. And while I wouldn’t compare a riflescope to a good spotter, I don’t have to worry about carrying them both.

The B25 is very clear, regardless of magnification I found my eye was quite comfortable focusing on my target, and the parallax adjustment made both downrange and reticle very clean. Any scope looses much of its brightness as you zoom in, but even at dusk I had no problem seeing and holding perfectly on very distant deer. It was also very handy in picking out Marmots from their hides in and around the boulders.

The new EREK 2 elevation turret is one of my favorite features of the scopes. The turret has a lock ring that you simply pull up on, and it engages the turret keeping it from being rotated. I like the idea a lot more than the pull-up/push-down turrets, it seems like a much stronger design, and less likely to be damaged or messed with. The turret lock is also used when re-zeroing the scope (see video below). The EREK 2 turret has a tool-less zeroing feature that allows you with your bare hands to quickly reset your scope’s zero, I found this feature incredibly useful. On any given day, my density altitude can vary from 4000 ft up to 11,000 ft depending on atmospheric conditions. With drastic changes like that, its nice to be able to quickly adjust my zero, without needing to break out my tool bag. The windage turret also locks, it is much simpler, and of the push pull design. I have no problem with that since I rarely dial wind, due to its fickle and switchy nature.

With so many options today, there is literally something for everybody. The new lighter weight of the US Optics B25 is a great excuse to re-scope my rifle, as I have become quite accustomed to having more scope than some would deem needed. I think there is plenty of room for larger tactical style optics in the hunting realm, obviously they will only appeal to those willing to carry it. I for one have seen the value of these scopes, and the advantage they give me.

I hit the field with the B25 in earnest, after some range time which consisted of a couple rifles chambered in 308win, 300wm, and also a big one chambered in 408 Cheytac. I figured if the big calibers didn’t hurt the B25, then surely my Desert Tech SRS A1 Covert wouldn’t do it any harm. Most of my shooting was using my little Short Action Customs 223 Remington barrrel, but I also shot 6.5CM, 308win, and 338LM with it. Again, the quick re-zeroing of the turrets made these transitions very easy. The high magnification of the scope was also very handy when trying to shoot tiny groups on paper, something I am not very good at, so I avoid it whenever possible. It also proved valuable when shooting at distances beyond what most routine shots are taken at, I managed to shoot an 18 inchish group at 1133yds with my little 223 Rem. Through the clear 25X I could see my trace coming down on the target, and the impacts and voids left by my bullets. Switching from one target to another I dialed back and forth, the audible clicks were also crisp, allowing me to count them even if I wasn’t looking up at the turret. I also noticed the magnification ring was not as stiff as many other scopes I have used, I don’t think a cattail would be needed on these scopes but for serious competition.

Shooting with this scope felt like a chat with an old friend, everything where it was and as it should be. Dope lined up meticulously where I expected it to, and nothing ever surprised me. I found it difficult to find a downside to the B25. Of course for a scope mounted to a mountain rifle such as mine, you could always wish for something lighter, or more compact. But I fear until new manufacturing and materials become available, it will be hard to make them much lighter, or smaller. But I am sure that when it happens, companies like US Optics will be the first to bring them to market.
