Ratings & Reviews
Surefire Procomp muzzle brake.
This brake actually helped my accuracy with the heavier 77 grain handloads! It stabilizes the barrel very well of course, but I don't believe that is the reason it has enhanced the accuracy of my 18" 1/8 twist barrel. It has to be in the design, and being Surefire, I am sure they did not slap one together without any engineering. Now I know why so many match shooters use them. A great brake, at a great price.
Great comp, new favorite
I couldn't believe the review videos but they're all true. This comp leaves my 16" rifle dead centered with very little recoil at all during rapid fire. Best I've tried to date for fast target re-acquisition with a red dot. Being surefire I would expect it to be quality design and finish but I also would expect it to cost 4x what it does. Best bang for the buck imo. Noisy, but it does exactly what it's designed to do.

This muzzle device is one of the top five muzzle breaks in the USA I like it and I like the price thank you primary arms for your fast and reliable service.
Surefire quality, low price. It was easy to install and works much better than the BCM mod 0 that I was previously using.
PA is the best

This brake works as intended. It allows quick follow up shots and accurate rapid fire. However, since it is not a flash hider, it would not be good to use with night vision or night firing in general. If you do any work with team members close at your side, it would not be good to use, since the blast is pushed out to the sides. This would be true of most any brake. As expected with a brake, it does increase the noise level but not too bad. Good product that works as advertised, just know its limitations.
Surefire procomp muzzle breaks work
These work great. I have them on two of my AR's in 5.56 they are loud though. But boy do they work!
Great service-Great brake!!

Great brake, a little louder than the Claymore brake it replaced but, what the hell, let’s make some noise!! Does a fine job of canceling out recoil. Excellent service from PA as usual, 3 days ground shipping to the Tundra of northern MN.
