Surefire procomp muzzle brake - SureFire 5.56mm 1/2-28 Threated Muzzle Brake

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 was kind of rough. The blast bouncing off the shooting lane walls was crazy. The first shot shocked me and silenced the entire range with how loud it was. Even the range warden looked over to see what kind on cannon I was using. With that being said I like and recommend the Brake. I don't like people in my blind spots when I am shooting so the blast radius is a plus. This Brake works great outdoors and my son is going to get one for his AR as well.
