The Shrewd #3 Muzzle Brake is designed to significantly reduce recoil and muzzle rise with a single expansion chamber and 42 ports angled forward.
Installation requires gunsmithing to enlarge the exit hole to be .020" larger than the bullet diameter, and it can accommodate up to .44 caliber bullets.
Made from 4140 chrome moly steel with a silver finish, it measures 2-5⁄8" long with an outside diameter of .850" and is for universal rifles with 9/16-24 threads.
