  • Spacers

    The muzzle brake I'm sure works great the only thing Gamma didn't include was spacers to ensure proper timing. Right now it's tight at the ten o'clock position with the crush washer on. I will be getting rid of the crush washer and just go with muzzle spacers.

  • Best brake I've used.

    The Gamma is my favorite brake. It looks good and performs even better. I bought another for my new build after the first one I used on a piston driven 14.5 556 worked so well. Its got a mean bark but not from the shooters perspective. The blast is significant towards the sides but its not a big deal. The best thing about this brake is how well it mitigates recoil and muzzle rise. Turn your AR into a tack driver and stay on target with this little beast. Like I said, it's my favorite and when you can find it under 7p bucks,its definitely worth it.
