For anyone considering a break on an AR consider the Miculek. I put one on my gun this past week and I will say it makes a HUGE difference. Recoil was not much more than a .22 on steroids and off hand I can easily stay on target with double taps and fast shooting. Other brakes cost a substantial amount of money and wont always provide the same results. The miculek is a very cost effective and money well spent to reduce recoil and muzzle jump. I found that Midway had these brakes for the best price of anywhere that I found them.
