What recoil? by Daniel Pugh, Verified Owner, August 20, 2021
This thing pretty much made all noticeable recoil and barrel movement disappear shooting m193 ammo out of a 16 inch barrel. It looks awesome and the quality is second to none, fit was perfect and easy to install

Surefire sfr by Steve, December 19, 2020
Very easy to install with a crush washer,, put on a 16” barrel and it works great,, helps with muzzle climb when doing rapid fire and also helps with felt recoil, I was recommended this product from a friend of mine that was very happy with it

Surefire ProComp Muzzle Brake by Barney, October 16, 2021
The ProComp Muzzle Brake works very well. The Machining is very good as all SureFire products are. The Brake controls recoil to almost nothing and the muzzle climb is also almost nothing as well. The first time I used it was at an indoor range and it...
