JE Machine Tech AR-15/M4 Muzzle Brake by wm price, Verified Owner, July 30, 2024
The JE Machine Tech AR-15/M4 Muzzle Brake is a lot better then the stock break that came on my 5.56 barrel. It is not as loud and smoother shooting. The bullseye is not a problem.

same size as a A2 Standard flash hider by Sage, Verified Owner, October 28, 2023
