The Shrewd #4 Muzzle Brake for .22 caliber features a multi-port design with a single expansion chamber and 42 ports to effectively reduce recoil and muzzle rise.
Installation requires gunsmithing, and the brake comes with a .220" exit hole that can be enlarged to accommodate bullets up to .44 caliber.
Constructed from 4140 chrome moly steel with a silver finish, it measures 2-5/8" long with a 1" outside diameter and is designed for universal rifles with 5/8-24 threads.
