Multi-Chamber Design For Efficient Muzzle Control Without Excess Noise & Blast
Three expansion chambers provide up to 45% measured reduction in felt recoil. Triple baffle, exhaust slots redirect noise and muzzle blast away from the shooter. Gives high volume shooters a quiet sounding brake that's easy to clean. Closed bottom keeps exiting gas from blowing up dirt and debris. Tapered shank for easier fitting to different barrel diameters. Adds 1-1/4" to barrel length. Comes with a thread protector.
NOTE: Calibers above 223 the muzzle brake must be drilled out.
