Brownells Brownells Brownells 75th Anniversary - A Shooting Heritage

Dual, curved restrictor plates with a tremendous amount of surface area stop exiting barrel gases and pull the barrel forward to counteract recoil and muzzle flip. The front sight or scope stays right on target for a faster second shot, plus less felt recoil and shooter fatigue. Models available for rifles chambered in .223/5.56mm and .308/7.62mm.
