Witt Machine Mosin Nagant Muzzle Brake

mosin-nagant-brake

If you own a Mosin Nagant, which I’m sure many of you do, then you probably know that sore feeling the day after shooting it. The folks over at Witt Machine have come up with something to help take away some of the sting from shooting 7.62x54r. They have some pretty interesting looking muzzle brakes for the 91/30 and M44/M44 Type 53 Mosin Nagants. They’re CNC machined from 7075-T651 Aluminum and hardcoat anodized. According to Witt Machine they reduce 60 to 70% of the Mosin’s recoil and muzzle rise. Their muzzle brakes simply twist on around the front sight and are held in place with screws. The M44/M44 Type 53 muzzle brake retails for $89 and the 91/30 muzzle brake retails for $85. Check it out in action below.

7075-T651 Aluminum has a tensile strength of 83,000psi, yield strength of 73,000 psi, and a shear strength of 48,000 psi. These values are before the hardcoat anodizing which creates an outer layer on the aluminum that specs out at 60 Rockwell.

During testing we found that the 5 port design makes the most efficient use of the available gasses exiting the barrel to substantially reduce recoil. There are 20 .078″ holes drilled into the top of the brake that vent gas in order to stop muzzle rise. The bottom of the brakes have no holes or ports to kick up dirt all over the shooter. Having the bottom of the brake angled outward also helps to reduce muzzle rise.

As part of our manufacturing process after the muzzle brakes are machined they are finished with a large vibratory tumbler using Ceramic media in order to provide a smooth matte finish prior to Anodizing. The brakes can be used as is, or painted/coated with any of the gun coatings commercially available. We also offer Cerakote coating on all of our brakes.

    Nope. Part of the fun is the recoil. And the noise. And the fact that it is one of the simplest rifles I’ve shot. It doesn’t need anything other than what it was made with.

    I love my Mosin.

    • gunslinger

      make big boom!

  • Andy

    I put a limbsaver over mine and can shoot it all day if I want.

    • DiverEngrSL17K

      The Sims Vibration Laboratory slip-on Limbsaver ( in the “Small” size for a Mosin-Nagant ) is a very sensible way to do it without ever altering the original configuration of the rifle, OEM steel butt plate included. Good call, Andy!

  • Gyufygy

    Because more muzzle blast is exactly what a Mosin needs!

    Also, would you have to do anything special when using corrosive ammo, or just clean the brake out along with everything else like normal?

    • Sam Schifo

      I’m assuming you would just clean it like normal. It is anodized aluminum after all, so it should have good corrosion resistance.

      • Ken

        I think he means the parts of the barrel covered by the brake.

      • DiverEngrSL17K

        I agree with the first part of your comment. However, please note that the WM muzzle brake is manufactured from machined 416 stainless steel, not anodized aluminum. It is available in a choice of black, FDE or desert sand Cerakote for an additional $15.00 if you so choose.

        • Sam Schifo

          Directly from their website “…precision CNC machined from 7075-T651 Aluminum and then Type III Hardcoat Anodized in a matte black color.” Their M91/30 specific model brake is made from alumnium, they do, however, make custom brakes in 416 stainless.

          • DiverEngrSL17K

            Thanks, Sam — I forgot to mention the customized option. The anodized 7075 aluminum brake is “standard” issue for the M91/30, M44 and SKS. The 416 SS option is available for these guns, and is also pretty much standard for most other rifles as offered.

    • JtheJD

      After shooting corrosive ammo, use soapy water to clean the barrel.

      • gunslinger

        windex?

    • DiverEngrSL17K

      Clean the brake as per normal — it’s made of 416 stainless steel, with Cerakote as an option.

  • Yellow Devil

    I’ll be honest, after the first time I shot my Mosey I was sore. The following time however, instead of shooting supported, I shot the rifle either prone unsupported or sitting unsupported and I wasn’t hurting at all afterwards. I even went through all my rounds that time and it was still pretty accurate without any bench support. If anyone gets sore from their Mosin, I advocate trying out different firing stances next time.

    • hkryan

      I’ve had the same results with other rifles. More support = beat up shoulder.

  • Zachary marrs

    If I see anyone with this on a mosin carbine, I will f**king kill them

    • displacer

      yeah that’s reasonable

      • Zachary marrs

        Hve you been next to a m44 when someone decides to touch it off? This will make it even worse

        • displacer

          I have a Witt brake on a 7.62x54r VEPR with a 23″ barrel. It’s honestly not that bad relative to a bare muzzle, the blast is already so massive that you can’t do much to make it worse short of cutting the barrel shorter. It’s like complaining about a brake on a BMG, either way it’s gonna suck no matter what

          • Zachary marrs

            Yeah, its the carbines with the brakes that I dont like

    • Machinegunnertim

      The gun fashion police are in full hate mode when something like this comes out.
      If it was a pink mickey mouse front sight hood replacement then i could see the justification but some people just have to act like A***holes. Worry about your own guns not mine.

      • Zachary marrs

        I qill, untill you sit next to me and shoot this at a range, its called common courtesy

        • Machinegunnertim

          Just how close do you sit to the muzzle of other people’s rifles?!

          I normally shoot on private or public land where no one else is around but last time I was at a crowded range each bench was spaced far enough apart that my neighbor would never have noticed blasts from this. Especially with the common barrel lengths being far forward of the bench. So again, worry about you own guns.

          • Zachary marrs

            My local range has bays about 4 feet wide, and mosin nagant carbines already are plenty loud, muzzle brakes make it even worse. You sound like one of those jerks who sit next to a new shooter with a .22, and pull out the largest gun they own.
            You are fine with whatever on your gun, until you decide to be the biggest asshole there

          • Machinegunnertim

            I find your accusation to be very offensive and no I am not “one of those jerks”. Guess what!? You have the ability to walk over to that person and tell them that the blast from their rifle is too much for the .22 shooter. Imagine that!

            These comments seem to be full of negative people that can’t stop themselves from whining and complaining about blast and concussion form firearms. If you can’t handle it then stick to bows and BB guns. Otherwise, talk the other shooter, move to another spot, or man up and stop being a wussy just because someone wants to put a brake on a small arms caliber. And YES I consider 7.62x54r to be small! The only time I ever noticed real muzzle blast was when spotting for an M2 gunner and .50 BMG on full auto really pounds the jaw. But it never upset me or made me think that it was unbearable. You guys need to man up stop crying act like men. If you have a youngster that is affected by the blast then refer to my other solutions.

          • RealityCheck

            I present to you the “it’s all about me” generation. They’re always on the lookout for something to whine about, something they can get “offended” about. And they don’t know how to “man up” – the zipper on their pants is on the side.

  • kbroughton77

    • hkryan

      Or breaks you…

      • gunslinger

        gun muzzles you?

  • ilike_waffles

    Why? Please tell me why? A muzzle device that cost and is worth as much as a Mosin rifle. I want off the spinning planet!

    • Cymond

      The days of $85 Mosin-Nagants are long over (unless you’re only looking at, like, a wholesale price without shipping or transfer fees or something).

      • Hopsaregood

        Okay, two thirds or three quarters of the price of a Mosin.

  • SM

    I often shoot mine all day (off and on all day…) without much trouble. If anything, my left arm gets the most sore for holding up that 28″ barrel.

  • VeriAeq

    Ridicule the thought of a Mosin muzzle and in the same breath brag on an AR muzzle, interesting.

    • Zachary marrs

      Ar vs mosin
      5.56×45 mm vs 7.62×54 mmR
      36-80 gr. Bullet vs 150-200 gr. Bullet
      Around 28 gr of powder capacity vs 64 gr. Of powder
      Do you see the difference?
      Have you been next to a discharging m44?
      It ain’t fun, I’ll tell you

      • VeriAeq

        I did not intend to ridicule (see earlier posts), it was sarcasm, only sarcasm. I do have a brake on my 91/30, helps keep the muzzle down to help keep an eye on hits. My Steyr model 1895 8x56R on the other hand reaches for the sky (no brake), keeping sight picture with this are you kidding me ;-). My frankin AR does not have a brake (only a flash sup.)

      • the ammo addict

        The larger volume of high-pressure gas means a properly designed brake will be more effective on the M-44 than any 5.56mm gun. I do agree it will be loud and unpleasant for anyone around, just like a Hakim or 50 BMG. As a courteous 50 BMG rifle shooter, I will locate myself away from other shooters if possible, and if not possible, I let them know it’s going to be insanely loud and ask them if they mind (I can always shoot something else in the mean time). Also, letting them and their buddy each fire off a round makes friends :)

  • Cymond

    It’s nice to see that a company is making a good quality clamp-on brake. I’ve read too many reviews of those cheap clamp-on NcStar (or UTG or whatever) brakes flying off because they couldn’t handle the pressure. I’ll probably get a brake sometime after I get a new front sight. I sent mine off to be customized by a formerly-reputable smith and never received it back.

    • DiverEngrSL17K

      Cymond, I’m really sorry to hear about your experiences with said gunsmith. I can vouch for the fact that you will definitely not be disappointed with the WM muzzle brake once you’ve tried it, provided you follow the manufacturer’s installation instructions closely. This is, of course, assuming that you know and accept ahead of time the trade-offs involving use of this muzzle brake versus not using it for your particular applications ( and I have absolutely no doubt you know exactly what you want and what you are doing ). if you haven’t already read my previous comments and recommendations on this post, perhaps they will contain some information based on my experience with the WM muzzle brake that will prove at least a little useful. Hope this helps a bit.

      Oh — and wishing you, and one and all, a Happy and Safe Fourth Of July!

    • the ammo addict

      I’m done with clamp on brakes. I had one of the NcStar AK-74 style brakes for an SKS that ended up going down range before I even got through 10 rounds. The screws holding it on sheared right off and there was absolutely no evidence of a bullet strike in the brake when I recovered it. I will say that the brake did provide noticeable recoil reduction and an increase in muzzle blast while it lasted, but I’m done with clamp one stuff.

      • Cymond

        The problem wasn’t the clamp-on design, it was the NcStar junk materials.

        • DiverEngrSL17K

          Exactly — good call!

  • DiverEngrSL17K

    While I agree that the Mosin-Nagant rifle should be left exactly as is ( in it’s original configuration from a historical standpoint ) and does not need an after-market muzzle brake ( if you have “sore shoulder ” issues with the recoil and steel butt plate, you can get a Sims Limbsaver slip-on recoil pad in the “Small” size that fits perfectly and is easily removed when you’re done ), I will definitely vouch for the quality, fit and function of the Witt Machine muzzle brake. I installed a bolt-on model on my Weatherby Vanguard 2 in .300 Weatherby Magnum, complete with a Knoxx Axiom recoil-reducing adjustable stock, and it does the job exactly as advertised, provided you follow the manufacturer’s instructions properly. I went two steps further and used Loctite High-Temperature Red for the muzzle brake, and it has worked flawlessly ( not that these extra steps are needed, but I had my own reasons for doing so, such as considering this a permanent installation sans barrel end thread-cutting ). Bear in mind that you must use a good pair of vernier calipers to get the exact O.D. measurements on your barrel EXACTLY per Witt’s instructions when you order the muzzle brake. If in doubt, don’t hesitate to re-measure your barrel until you are absolutely sure of the dimensions. For those of you who prefer the security offered by a threaded muzzle brake instead, WM also has those versions available.

    • CA

      You won’t get it back off with loctite red.

      • DiverEngrSL17K

        Good point, and thanks for the comment, CA.

        In spite of what Loc-Tite says, removal is still possible, although additional deliberate thought and effort is required. If Loc-Tite Red is applied to the retaining screws, they can be removed with the aid of a small impact wrench ( short bursts only ) without damage. WM recommends applying Loc-Tite ( Blue ) between the O.D. of the barrel and I.D. of the muzzle brake ; if Loc-Tite Red / High-Temperature Red is used instead, final removal can be effected by heating the brake carefully with a propane torch ( don’t use too much direct heat to avoid damaging the brake, and remember that even High-Temperature Red has a limit well below that of the brake itself ) and then prying the clamp slightly apart before twisting the brake off gently with a small padded pipe wrench. All this presumes that you have at least a small workshop with the necessary tools to do the work properly. If you don’t, or are uncomfortable doing the work, stick with Loc-Tite Blue. Although WM recommends using standard Loc-Tite Blue, for one’s peace of mind it is worth spending the few extra dollars on High-Temperature Blue because of the higher temperature limits. Both High-Temperature Red and High-Temperature Blue can be found for sale on Amazon.

  • 1leggeddog

    Wait a minute.. this is.. clamped on?

    It’s not threaded on?!?

    How does this ensure it won’t go off bore axis and explode ?!?

    • gunslinger

      because it gots the screws.

      seriously though, i’m with you. but who wants to thread an old 91/30 barrel?

      • RPK

        The muzzle device costs more than my Mosin did! Crazy talk.

    • DiverEngrSL17K

      Take a good, careful look at the mechanical design and structural details of the WM muzzle brake, and you’ll understand why it works so well without any issues provided you do the initial sizing and installation exactly per the manufacturer’s instructions. A good place to start is the Witt Machine web site where they explain how it works ( and they are not exaggerating just to make sales, either ).

  • raz-0

    OK, a muzzle brake made out of aluminum? How quickly will that erode?

    • DiverEngrSL17K

      It isn’t made from aluminum. It’s made from machined 416 stainless steel, with an option for Cerakote if you prefer.

  • Adam

    Might go well with some fugly aftermarket stock. Looks terrible on a bone stock Mosin. And it’s pretty spendy considering the cost of the rifle it goes on.

    If I put one on my M44, how am I supposed to fold out the bayonet and stab old TV’s and junk?

    • DiverEngrSL17K

      Sorry Adam, as with most things in life, you can’t always have your cake and eat it too, firearms modifications included. I definitely agree with the opinion about the bone-stock Mosin, though ( I’m a purist when it comes to a historical firearm like this ), although I’m also a believer in the Witt Machine muzzle brake based on experience with other rifles ( please see my other posts on this subject if you haven’t already done so ).

      End result? I would say keep your M44 the way it is — historically and mechanically accurate. It is perfect exactly as is!

  • Leigh Rich

    That woud nake it more manageable…

  • Leigh Rich

    Cost as much as I paid for each one of my mosins with accessories.

  • LouGots

    I should like to see test data measuring recoil energy with and without this (or any other) muzzle brake. This should not that hard to determine.

    There are differences between recoil energy, which is scientific fact, and felt recoil, which is affected by the weight and configuration of the firearm, as well as as how it is held.

    Even more susceptible to distortion than felt recoil is perceived recoil, which is in the province of psychiatry. For example, the loudness of the report might make one imagine that the discharge of the firearm produced more energy. Similarly, having spent money of a muzzle brake could make one imagine that the brake significantly reduced recoil energy.

  • Seth Hill

    I’d prefer to have a threaded one over a clamp on. Guess I will have to make my own.

    • the ammo addict

      Same here. I had one of the NcStar AK-74 style clamp on brakes for an SKS that ended up going down range before I even got through 10 rounds. The screws holding it on sheared right off and there was absolutely no evidence of a bullet strike in the brake when I recovered it. I will say that the brake did provide noticeable recoil reduction and increase in muzzle blast while it lasted, but I’m done with clamp one stuff.

      • DiverEngrSL17K

        You are not going to have any issues with the Witt Machine clamp-on muzzle brake over the long run, provided you follow the manufacturer’s instructions for sizing and installation exactly. The fit, finish and outright mechanical and material quality is outstanding. I have one on a Weatherby .300 Magnum rifle and have never encountered the slightest problem after repeated firing.

  • Machinegunnertim

    I got one a while back and it’s great. Does not permanently alter the rifle. Why wouldn’t you want to lower the recoil? I have introduced a lot of new shooters to firearms with this rifle and having something like this helps a whole lot.

  • DiverEngrSL17K

    To All :

    Please note that the Witt Machine clamp-on muzzle brakes are manufactured from machined 416 stainless steel, and not aluminum alloy as some seemed to have presumed. A black, flat dark earth or desert sand Cerakote coating over the stainless steel is available as an option for $15.00 more.
