Riton Optics RTS Mod 5 6-24X50 Riflescope

The optics race is a nonstop fight to get the attention of prospective shooters. It has been exciting if nothing else to watch some of the developments over the past decade or so, particularly from a consumer’s point of view. But have there been any real game changers?

I am always on the lookout for good optics, as I am frequently approached by friends and others looking for good shooting options. And optics is one of those heavily fielded questions.
So when I had the opportunity to try out one of Riton Optics scopes, I jumped at it.

Riton is a fairly new manufacturer, I had hardly noticed them before getting hands on one of their scopes. That scope is the RTS Mod5 6-24X50, it is a first focal plane scope, which is a must for me anymore. It has a traditional configuration with a side focus/parralax adjustment, an illumiated proprietary reticle with the rheostat ontop of the eye box, and a focus ring at the back.

First Focal Plane reticle

The reticle and turrets are both MOA, I’m more of an MRAD fan, but at least they both match. It wasn’t that long ago that many scopes were a hybrid mix of MOA and MRAD, thank goodness those days are gone.
I like the reticle, I found it very useful for measuring corrections and holdovers. Being an FFP reticle was also very handy, avoiding any kind of field math is a plus for my slow processor.

The turrets feature a push pull locking system, to keep them from being turned unintentionally. There are fifteen minutes per revolution of the turret with a total of 70 MOA internal adjustment, that is plenty of adjustment for the kind of shooting I do. I ran the scope on two different rifles, first on my 6.5CM MDR, a bullpup semi auto multicaliber, and then on my brand new 25Creedmoor, a custom built bolt rifle in an impressive new caliber. Both rifles shoot well beyond a kilometer, and the Mod 5 had all the elevation and power I needed for such shots. (Scope was mounted in a 20 MOA cant on both rifles)

While shooting the MDR I became quite familiar with the features of the Riton scope, though it took me a second to revert back to MOA.
Engaging targets as far as twelve hundred yards was no problem with the Mod 5. I am not a large magnification shooter, I usually have about five to ten more X’s than I need, but most of the time I shoot between eight and sixteen power.

I think that is where the Mod 5 shines, as with most scopes, you loose some clarity and brightness at the higher magnification. And in my experience, the lower the price point on the scope, the higher the disparity in sharpness at high magnification.
The Mod 5 was no different, I did find that at twenty four power it was a little difficult to pick out little details out past the grand mark. I solved the problem by backing off to eighteen or twenty power for those long observations. I also wish I’d had a sunshade for it, most of my scopes use one, and it is very apparent when even a little bit of sunlight hits the objective. Luckily, Riton has me covered, and Ive got a shade on the way.

I also ran a test on the click values, they were consistent, but slightly off. Over the course of the forty nine minutes of available elevation from my zero, the click value was on average 0.262 MOA. Again, thats a little off, but it was consistent. The good part was it returned to zero perfectly every time, and no significant reticle wandering or cant.
There was a time that I wouldn’t have trusted a sub 1000$ optic to be precise for repeatable turret travel in serious long range shooting, but technology has caught up it seems. And now scopes like this one are showing that not only can it be done, it can be done well.

The Mod 5 weighs in at thirty ounces, which isn’t necessarily light when compared to it’s competition, but its not particularly heavy either. For my taste, it’ll do just fine. I am used to hauling heavy guns all over these mountains, so switching to something this light was very refreshing.

I ran the Riton pretty hard, up and down, zooming in and out, hiking across mountains and riding up dirt roads in the bed of a truck, semi auto fire,  mounting, re-mounting, etc. No issues with it so far, it keeps right up with me.
All Riton scopes are guaranteed for life, with no hoops to jump, or rules to follow. Thats good to know, becasue we all know about Murphy’s Law.

There was plenty of things to like about the Mod 5. I like the reticle, and the the glass is inline with the price point, the internals appear to be robust and repeatable, with simple turret rezeroing. I will also say this, according to the medical practitioner, my eyes are in pretty good shape. So I tend to second guess my own approval of some optics, mainly because what looks fine to me, is usually pretty crummy when someone with anything less than great vision tries it out. I was happy that the Riton RTS Mod 5 got more than just my own approval. The clarity and quality of the imagery seen through the scope was exactly what I would have expected for a scope in this price range.

If I had to pick out the things I dont like about it, I guess that wouldn’t hurt either;
-MRAD for starters, its not 1987 anymore. I know there are some misguided souls out there still addicted to minutes, but the rest of us have graduated to MRAD. Having both options would greatly improve this scopes desirability to a larger audience.
-Turret rotation graduations, would be very helpful to see what rev your on.
-Parrallax, seemed a little off at times, not bad, but requiring frequent adjustment and checking.
-Magnification ring, the texturing was counterintuitive, making it slightly uncomfortable from the shooting position to zoom in or out. This is a very small gripe, and could simply be preference.

I dont want to sound too hard on this scope, because I actually do like it very much. Hunting season is here, and Junior and I have a date with several deer, and elk. I have all the confidence in this scope to get us on target, whether it be a head shot on a cow elk at four hundrd yards, or a high shoulder shot on a big cross canyon buck at eight hundred and fifty yards.

I look forward to a long future with this scope, and Im sure it wont be long till Riton brings something new. They obviously have the drive, adapting newer and better optics is inevitable. I’ll be waiting to see what that is, and I’ll make sure to have an empty set of rings available until it does.

US Optics B25

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.

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 EREK 2 Turret Lock

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 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 SR 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. 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.

Too much scope? Never!

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.

Vortex Optics Fury Range-finding Binoculars

I’ve said it before, I am a huge geek for optics and everything that goes with them. Something about quality and the edge that good optics give you gets me giddy.

Anybody who shoots at any significant distance should be familiar with laser rangefinders, otherwise I take their claims as what they are; hopeful aspirations.

It didn’t take me long to realize the need for a rangefinder in my shooting, and I didn’t want a substandard one. I bought my first rangefinder many years ago, it was a Leica. Over the years I have come to appreciate a good rangefinder, that Leica taught me a lot. It is absolutely necessary to make good shots at distance, and I’ve been lucky to have hands on quite a few of them. One of the first things I noticed when playing with LRF’s was that many of them were at best 80% of what they are rated for. And many of them lower than that. Ive come to find that a good LRF will actually go beyond its rated limits, in good conditions. With optics and rangefinders especially, you do get what you pay for.
With so many new and exciting things hitting the market recently, I was excited to get the chance to try out a new prodcuct from Vortex Optics
The brand new Fury Binocular from Vortex incorporates a 1600 yard laser rangefinder into a 10X42 armored binocular.

I’ve never had a rangefinding bino before, I’d mostly used just a plain rangefinder. I never felt much like carrying multiple optics into the field, nor could I afford it, but with the technological advancements we enjoy today there is no reason to. The Fury gives you high a quality ten power binocular, with clear and bright images. And ontop of that, it also serves as a 1600 yard rangefinder. For a hunter, I think it is the best of both worlds. Especially since you dont want to be carrying anything extra with you, unforgiving mountains are not the place to carry extra weight.

The Fury, like most modern rangefinders, allows you to select yards or meters. It also has a slope indicator that allows users to select line of sight distance (LOS) or use a corrected angular compensated distance (HCD).

The display on the Fury has a circle reticle for aiming at your target. Up and to the right of that, is the angle display, shown in degrees. The distance is shown below the reticle, and just off to the left there is a battery level indicator.

I have taken the Fury out many times now, used it in many different settings and places. One of the first times I tried it right out of the box, I managed to hit 1780yds with it. That was a building, and I didnt expect it to hit a deer at that distance. But its good to know that it can reach those kind of distances, even though in the real world of my shooting habits, it wont need to go that far. For me, I think being able to range the animals I hunt in the conditions and places where they live is the overall determining factor for performance. And in those places and conditions, the Fury seems to shine. Like this:

Hitting trees and rocks at thirteen, fourteen or fifteen hundred yards proved to be pretty easy. In the bright daylight of the sun, or in the angled afternoon light of the evening.

Hitting an animal at that distance would be hard, not necessarily because of the rangefinder, but because you cant hold still enough without a tripod. I find myself aiming for the nearest tree or rock in those scenarios anyways.

The beam divergence on the Fury, or the size of the laser beam for lack of a better explanation, is 1.6X.07MRAD. That isn’t bad considering the price-point of the Fury, there are a few better, but surely there are worse. Again I look back to the purpose of the Fury, at least in my case. It wont be often when I am looking at a deer, elk, or any other target that is standing on the horizon some thousand or more yards away, with nothing near it that I cant sink that laser into. So while a tighter beam dispersion might be better in some situations, I think this one will do just fine for my purposes. And I think it will do for most other’s as well, I assume I am not the only person who lases the target multiple times when targeting. Particularly when distances are extended, and critical to making the shot.
At 31 oz the Fury is very comparable to its competitors, it doesn’t feel heavy to me, which oddly enough seems like a bad thing. I know I’m crazy, but for some reason I like to feel the weight that usually accompanies quality. But I certainly wont hold that against the Fury.

The Fury comes with a nice shoulder strapped carrying case, it has a double shoulder harness, and it is secured with a a small hook and elastic strap to close it. I liked it, but honestly the Fury might be a little big/heavy for the case design. It also comes with your standard lens covers, as seen in the above picture. I feel for optics companies when it comes to lens covers, it can be a difficult subject. You can either go with cheap and easy option, knowing that users will likely upgrade to something more to their liking. Or you can invest in some very nice covers for them, and then risk people not liking them and wanting something else anyways. I found that the soft rubber options provided with the Fury are perfectly serviceable, and they are easily removed if not to your liking.
Both barrels of the Fury have a focus ring, the right barrel adjustment is to focus the display, and the left barrel adjustment is for equalizing the focus between the users eyes. I may have gotten a a mismatched set at the factory. Eyes that is, it has always been a challenge for me to get any pair of binoculars to stay in focus for me, probably due to the difference in my eyes. I noticed this problem slightly when using the Fury, but I am quite sure it is my eyes relaxing between uses.
The Fury has adjustable eye cups, with four different depth settings. The cups were easily adjusted to fit my eyes, with or without glasses. It also made it easy to adjust to fit the relief on my phone, so that I could get all these spectacular images 😜
The battery compartment on the Fury is located on the bottom, nice and out of the way. From this angle you can also see the two adjustment rings for focusing the unit.
For many years I have been using some great rangefinders, Leica as I mentioned, Swarovski, Sig Sauer Electro-Optics, among others. While the price of good rangefinders has come down, my budget for shooting accessories has mantained its place on the leger. But I felt the Fury was well worth the splurge, and my money was well spent with Vortex, as it usually is. I still have never had to use their famous no BS warranty, but it’s always nice to know it is there. Look for the Fury in upcoming stories and pictures, I dont see it going away anytime soon.

ES Tactical 6.5Creedmoor Barrel for the MDR

Just when I thought I was up to my ear’s in MDR, Eric Smith from ES Tactical found it expedient to dump another huge helping of MDR in my lap. It wouldn’t take long to figure out which way this would go.

As a guy with too many irons in the fire already, I took the 6.5 Creedmoor barrel with a grain of salt (I know you all feel my pain). Had it not been for my stellar experience with Eric’s work, I might have even backburnered this project. But instead, I took the first opportunity to stab my MDR with this latest addition to the pile.

Ive shot the MDR quite a bit, some might even say more than anyone else. The MDR is a multi caliber bullpup rifle. The rifle was first available in 308, it will soon be available to the public in 223. But for those of you that already have the gun, you can wet your multi caliber whistle without waiting by ordering a 6.5 Creedmoor from ES Tactical. I shot quite a bit of 308 in the beginning, and I loved having so much power in such a little package. With the 308 barrel installed, the MDR can put down a serious amount of hate and anger. But it is still quite capable of MOA accuracy, and at distance as well. Just a short while ago, the 223/556 conversion was made available to me. In the short time I spent with it, I became very enamored. The minimal recoil, and outstanding accuracy made the compact MDR even more desirable, you can read more about that here.

So you can imagine my excitement when the option came to try out the Creedmoor in my beloved little rifle. The Creedmoor offers the same accuracy as the other cartridge options, but less recoil than the 308, and a better envelope for distance as well.

I couldn’t resist the appeal, so I hurried up to my local shooting hole, and warmed up my trigger finger. Upon arrival I ran a few magazines of 223 through the rifle, just to get my trigger finger into shape, then set to swap the rifle over to the Creedmoor.


The MDR as seen with 223rem barrel (installed with YHM Turbo) Sixteen inch 308win, and the ES Tactical eighteen inch 6.5CM barrel

Since the 6.5 and the 308 share the same boltface, magazine, and a few other parts, there is only a need for a barrel assembly should your rifle be a 308. Since my rifle was currently a 223, I had to swap bolts, remove the magwell block and switch the magazine catch.
To see how the MDR is converted from one caliber to another click here

It took a few minutes, and I was ready to make some noise. Except I wouldn’t. I hate shooting without the proper muzzle accoutrements, so I attached one of my favorite suppressors, the Silencerco Hybrid. The barrel assembly from ES Tactical came with a six position gas key, allowing for refined tuning of the rifle. I found it quite unnecessary to figet with, as the rifle functioned flawlessly, it consumed and expelled everything I fed it.

Speaking of diet, I tried a few different things. I started out with Desert Tech munitions 140 grain match, I have always had good luck with it, and today was no exception. I also tried some of the more popular brands, such as Hornady 120 Grain Match As well as the gold standard Federal Gold Medal Match 130 grain And the very popular Prime 130 Grain Match

The accuracy results from this fine selection varied slightly, the DTM, and Hornady gave the best results. Both of them printed groups that were mostly hole, and little paper. The Prime and Gold Medal were not too far behind, it is my guess that the Berger and Norma 130 grain bullets used may perhaps be a bit more finicky with seating depth. Which may explain the larger patterns. DTM shown in blue, Hornady in red, Federal in yellow, and Prime in green

As you can see in the groups the stringing is horizontal on the better ones, it seemed to follow the heating of the barrel. The first three or four shots in each group were either touching or stacked. It was usually the fourth, fifth or sixth shot that were the outliers (I may have lost count a few times, I was enjoying myself😌). The lesser groups didnt seem to have any particular pattern. I only ran a chronograph on the DTM 140 grain ammunition, the average over a couple magzines worth of ammo showed 2610fps. I was quite pleased with the velocity from this 18 inch barrel, with a MV like that, coupled with MOA or better accuracy, this thing would be very useful for anything inside 1000 yards.

Being as familiar as I am with the platform, I have gotten used to it’s quirks and folleys. This familiarity has helped me avoid some of the little things that cause malfunctions, so it didn’t surprise me at all that I experienced no failures. I did note that the brass was coming out pretty dirty but otherwise fine, I suppose I could have dialed down the gas pressure a little after all.

The thread protector, threads, and crown of the ES Tactical 6.5Creedmoor barrel

In total, I shot probably 80 or so rounds (not counting the 223 appetizer). It was smooth shooting, the recoil was very mild, and with the suppressor mounted up, I could shoot all day. This setup would be awesome for a threegun carbine, it’d also make the perfect truck gun, or patrol rifle. So many possibilities, I doubt it will be long before the next flavor MDR comes along.

Should you find youself in need of a Creed for your MDR, give Eric a call over at ES Tactical, and dont forget he cuts awesozme barrels for your SRS, or just about anything else you might want too.

Here is the video:

The Desert Tech MDR in 5.56

There has been lots of excitement surrounding the Desert Tech MDR lately. With some rifles shipping since late last year, and many more about to drop, the hype has reached its peak. The Micro Dynamic Rifle  brings Desert Tech’s multi caliber capability to a an auto loading rifle. All of the rifles that have been delivered to customer so far have been 7.62 rifles, but I got a lucky chance to get an up close look at some of the first 5.56 rifles. After a few hours of shooting it, I decided to write a little more about it.

The MDR is a bullpup rifle, and currently there are 7.62 and 5.56 conversions available for it. I have spent extensive time with the 7.62 versions of the rifle, and have found it to be a very fun rifle. The function of the rifle is very intuitive, the controls may take a moment to get used to but are otherwise very friendly. In my experience, the controls wear in with use, and only get better. The initial feel is that the mag release is stiff, and the trigger can be a bit scratchy. But with some range time, both of those issues go away, and the trigger is quite nice. I dont even think about the mag release anymore, it is smooth and easy to operate.

The MDR has big shoes to fill. As many of you are aware, Desert Tech makes some of the best precision rifles available today. And having sired the MDR, Desert Tech is expected to bring the same quality and presentation its other rifles are famous for. Quality triggers, better accuracy than the competition, all in a multi-caliber rifle shorter than its peers.

Having had plenty of trigger time with the 7.62 version of the MDR, I was very excited to try out the smaller conversion in 223/556. I was actually lucky enough to assemble the rifle from scratch. Or at least, from a small pile of parts. Click here to see assembly.

After some humbling experiences, I was happy to see the gun work like it had been built by the pros. It took very minimal tuning to get the rifle running just like a swiss watch. It was time to take it out into the wild, and get it hot.

 

Coldboremiracle Junior feeling out the MDR

The 5.56 MDR was a dream to shoot, comparing it to the 7.62 version of the rifle, which has significantly more bark. Recoil was negligible, a smooth and solid impulse. The ejections system pumped the hot brass out forward and to my right, making nice little piles. The rifle manages almost like a pistol, it is very easy to keep on target even during sustained firing. I used the gas block mounted Desert Tech Reflex Optic for much of the shooting. But it didn’t take long for the marksman in me to come out, so I switched over to a Kahles 312i for some accuracy testing. After all, only accurate guns are interesting, at least to me.

I also couldn’t pass up the opportunity to try out my new Yankee Hill Machine Turbo 556 suppressor. The MDR was a perfect host for it, and its uncivilized to shoot unsuppressed. You can read more about the Turbo here.

I was shooting some 55 grain ball ammo for the majority of the trip. This same ammo usually prints groups in the one inch category with my other custom 223 rifles, and in the MDR it was about the same. Five shots was probably just under an inch at 100 yards. I also wanted to try one of my pet AR loads for long range, which included a Hornady 75 grain BTHP and some RL-15.

After getting the rifle sighted in, I was quite impressed with the MDR’s accuracy. This was the first group I shot after zeroing the rifle, its only three shots but clearly shows the rifle’s potential.  The MDR clearly likes this load with the Hornady’s, so I may have to revisit with more ammo , and more range.

The rifle functioned great through the three or four hundred rounds that I put through it. There were only a couple issues that I quickly resolved, a spring that is part of the ejection system had not been installed properly. I cant blame anyone but myself there, and after I corrected the problem it was flawless.

I tried out several different magazines in the rifle. First I had to try the classic GI metal magazines that surely litter ever gun room across the country. The mags fit perfectly, fed like a million bucks, and even dropped clear with no need for assistance. I also had a couple Brownells Gi clone magazines. I bought them a few years ago on sale, as far as I can tell they did a great job cloning the old magazines but with new coatings and Brownells quality. In addition to those two types, I also tried out some standard Magpul Pmags, in both 20 round, and 30 round configurations. I am happy to report that all of them worked great, no feeding issues at all. That should come as good news to all those prospective MDR owners who already have a broad magazine inventory.

Another big concern to those interested in the MDR is the adjustable gas system. The rifle I build had a three position gas selector, though I understand that a selector with more settings (five or six) will soon be available for all MDR rifles. That said, this rifle worked great with the standard three position gas selector. I ran it on adverse for the first hundred or so rounds, to help break it in. I then changed it over to normal, and then to the suppressed setting when I attached the suppressor. I can see where a gas valve with more choices would be helpful, as even on the suppressed setting there was enough gas exiting the receiver that I could smell it. But honestly it wasn’t a big deal to me, I kept shooting along without any concern. If you shoot in an enclosed or indoor range, I could see it maybe becoming an issue. But easily resolved with a lower gas setting.

I also decided to see how the gun would run without the ejection chute installed, I have seen and been asked many times how it works. For me it isn’t a big issue, since in my experience most ejection issues/jams in the MDR are not related to the chute. But I can understand why some would want to know, so I gave it a try. With the chute removed, the gun ejected brass directly out and to the rear, about to my four or five o’clock. It occasionally would throw one to the three o’clock, but it didn’t seem to care, as it continued to chew through the rounds. Speaking of chewing, the 556 conversion on the MDR seems to be fairly mild on the brass. I assume it is because of the larger extractor to rim ratio, as well a smaller gas volume and recoil impulse.

My overall impression with the 556 MDR was one of pure enjoyment. Perhaps Im just used to shooting the 762 version, and other heavier recoiling rifles, but I just couldn’t stop pulling the trigger on this gun. The accuracy makes this rifle at the top of my wish list, and I intend on getting some more time behind it soon. Perhaps a coyote hunt or some other adventure. I will be getting one as soon as conditions permit, and probably a 6.5Creedmoor barrel to go with it for more serious work such as distance.

For those of you waiting for the 556 MDR, hang in there if you can, it is worth it.

Oh Wait! there’s a Video too:
