Cuts Recoil & Muzzle Rise With No Increase In Muzzle Blast Or Noise; Money-Saving Design
Single expansion chamber with multiple ports that interrupt and align exiting muzzle gases to increase accuracy and cut down on painful recoil. Elliptical, rear, exhaust holes force hot, expanding, muzzle gases forward, away from the shooter’s face and ears for no increase in total noise to the shooter. All models feature a .250" diameter exit hole and tapered design (except the 4S); you can stock fewer recoil reducers and save inventory dollars. Simply open up the exit hole to .040" over bullet size and face back the taper at the rear of the comp to match the barrel diameter during installation. Slim-Line (SL) models are smaller in diameter to blend perfectly on thin, ultra-light, mountain rifle barrels.
