5.0 Rating Great Accessory - 8/30/2014
Reviewer: CK
I purchased this brake a few weeks back. It arrived about three days later, as usual. Getting the timing down with the shims was kind of obnoxious but it didn't take too long. After applying the rocksett and cranking it down I let it dry for a few days, then took it to my range. The first and most noticeable difference in performance is the absence of felt recoil; full power 5.56 feels like shooting a .22. Follow up shots were noticeably quicker and I was able to keep irons on target at all times. Another bonus was the slight boost in accuracy. While it could be all in my head, I was getting .25ish groups out of my ar at 50 yards as compared to 1/2 with a factory flash hider. As the operator, the rifle is slightly louder than normal, but nothing unbearable. Shooters to my sides did notice a dramatic increase in muzzle blast though. Overall, this brake is well worth the money.
