Witt Machine Offers Custom Clamp-On Muzzle Brakes

Witt Machine, which we originally covered off of their uniquely shaped “Muzzle Rise Eliminator” has seen fit to release a customizable clamp-on muzzle brake system. Witt claims a whopping, minimum 60% reduction in recoil and muzzle rise.

Recoil reduction is from 5 horizontal ports and 20 .078″ ports drilled into the top of the brake. The custom brakes are CNC machined from 416 stainless and can be installed with simple handle tools (hex keys and mallet, if needed for tight fits).


The brake system is also offered for drop-in deployment on the MOsin Nagant 91/30 (which would make shooting it significantly more pleasant with the stock stock) and a novel adapter for triangular Remington 700 VTR rifles.

The user-customization brakes are made-to-order “precision machined to your (emphasis removed) exact barrel specs. Tapered, Straight, or Stepped, we machine brakes for them all.”

Brakes require the potential customer to measure the first 1.5″ of their barrel in thousandths of an inch or hundredths of a millimeter. In case of measurement error, Witt will machine the brake again for free, customer only pays the shipping charges.

The base brake starts at $89 each. Users specify caliber (at no charge) and can choose from Graphite Black or Flat Dark Earth Cerakote for $15.

    I have no faith in humanity. Anything that requires a mallet, measuring to a thousandth of an inch and clamps on (which translates to “flies off”) seems like a recipe for disaster, or a lot of returned brakes.

    I’ve had this exact brake on my Remington 700P for like 3 years now and I can attest to it’s awesomeness, I can very comfortably keep the sight picture shot after shot and the side blast isn’t horrendous (for the shooter) but I still wear the earpro at all times – the hassle is worth it.
    No issues with the clamp on fit either, like a surgical glove, just make sure to use the vernier calipers and get the right diameter sizing at the various points along the barrel as Witt Machine stipulates.

    I have three of these: Two clamp on and one threaded. Calibers range from 6mm to .45-70. Recoil reduction is great. As to Bill’s concern about slippage, my .45-70 weighs 8 pounds, shoots a 325 gr Hornady at ridiculous velocity and has not moved. In .270, I am shooting 3200 fps, no slippage and feels like a .223. However, it’s up to you to measure carefully before ordering!
    The only problem (as with all muzzle brakes) is the shooter next to you on the line is not going to be happy.

    Muzzle breaks are an abomination. They could be useful in competition, as an attachment for a suppressor, or on full auto weapons. However without those caveats, people at ranges who insist on using these hearing destructive devises and can not control their weapon should be put in a corner and write on a black board 1,000 times, ” I can control my weapon.” And yes, neither my 404 Jeffery, nor 416 Rigby, or 500-3″-NE have such an abomination. In Africa some PH’s will not allow the hunter to use such a hearing assault devise.

      I can’t tell if you’re trolling or not…
      Have you considered wearing earplugs?

      • LG

        No, I do not believe that I am a troll. I just firmly believe that muzzle breaks, in 99% of the cases, are a harmful crutch. But do not believe me. In Europe it is considered poor manners to shoot without a suppressor. I know several young PHs in Africa that will not allow the client to use a muzzle break or compensator. Refer to DoctorDave’s last sentence. Of course, if I were to put a muzzle break on my 416 Rigby, I would soon have the whole range to myself. How would your ears, wearing protection or not, like to be slapped with the generated back blast? Yes on a 50 BMG, 416 Barrett, or full auto Thompson a compensator could be considered necesary equipment.

          You seem like you’re one of those old crotchety guys at the range who shakes their head and looks down on the younger guys shooting their AR’s. Guns are loud. If you don’t like it; try going to the range on a Wednesday morning when it’s raining. The rest of us will put in some ear plugs and blast away.

          • LG

            I am old and am crotchety. But i do have manners. But it amazes me how many “young” people need “crutches”. My first centerfire rifle was a 1903 Springfield, not the —-03A3 variety. If at 13 I could shoot that with surplus Mark I ammunition, why is the need for these devisees on popguns? I do not mind the AR platform. They can be good, reliable, accurate weapons. But I still say, if you need a muzzle break on a 5.56mm and it isn’t one with the Fun switch, then it becomes a crutch.

            Muzzle BRAKE. Spelling counts.

          “In Europe it is considered poor manners to shoot without a suppressor.”
          What part of Europe? In Italy for example shooting with a suppressor would be a, maybe polite, effective way to go to jail.

    I just got a clamp on one for a tikka. Super nice and very effective. Especially for about 100 dollars. They also custom cut each clamp on brake to fit your barrel contour.
