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.
