Tomorrow I am going to test four different brakes on 3 different AR-15s (14.5", 10.5" and 7.5"). I am not too concerned about "recoil" with a AR-15, but am interested in muzzle jump. We shoot quickly in CQB, so less jump will save time. In one event, shot at 10 yards, it would be very desirable to fire a double tap and have the two shots print with 5".
I ran a similar test last month and found that one brake worked well and a fancier one did nothing. I also discovered that a brake that worked well on a 14.5" barrel does not work on a 10.5". The back-blast blew my hat off.
I have picked up 4 more brakes at about $25 each.
The test will consist of trying each of them on each rifle at 25 yards. I put a black patch on a large sheet of paper and fire 5 double taps at it. I pull the trigger as fast as I can for the second shot. My theory is that the best brake will produce the second shots closest to the aiming mark.
The result looks like this:
Poor results
Good results
