Sure, we could make a "standard" muzzle device, but why do that when one can push the limits? 

We set out to solve a problem that has plagued legal firearms owners for years. When taking a barrel to the minimum legal limit with a permanently attached muzzle device, one was forever locked in to their barrel, gas block, and handguard configuration. To us, that's nuts. The SLIM series was designed so that shooters could permanently attach a muzzle device and still get their gas block and barrel nut over the device.

FREEDOM! Shooters are forever free to change their weapon's configuration without having to go to a gunsmith.

  • Faxon Muzzle Break

    Posted by Thomas Owen on Apr 17th 2019

    This is a fine addition to my build. I have a few of these, no complaints. I attached it to a 16" Gunner barrel because it is so lightweight. It looks good and works as it should.

    Good muzzle brake at a good price point. This is intended for those that have to pin the muzzle brake on the barrel, but I would suggest this muzzle brake for those looking to preserve lightweight builds as well. Heavier muzzle brakes can upset the balance of the barrel especially on follow-up shots. This brake does it's job. With an adjustable block and a gunner barrel I have no significant recoil or muzzle flip.

    Look nice on the barrel. Sweet for compliance states like Ma. that requires the break to be welded and pinned on any length barrel. Only complaint I have is the flats on it were hard to find a wrench that would fit, and I ended up having to use a adjustable. Would buy again if I have a barrel I might want to switch out handguards or gas blocks on.

  • Great Muzzel Brake

    I am pleased as usual with the quality of the product. I initially tried to order on the first run which was advertised as being pre drilled for pinning. I submitted the option to be notified when back in stock. The only disappointment I have in the muzzle brake is that it was not pre drilled. I do now remember seeing a memo that only the first run would be pre drilled, but it would only make sense that a .620 muzzle brake is only going to be sought after by those wanting to permanitly pin and weld a muzzle brake on a 14.5" barrel so they could change the gas block in the future. It would be my recommendation that they all be pre drilled.
