The Shrewd #1 Muzzle Brake for 22 caliber features a multi-port design with 42 ports to effectively reduce recoil and muzzle rise.
Installation requires gunsmithing, with a .220" exit hole that must be enlarged to .020" over bullet diameter, accommodating up to .44 caliber bullets.
Constructed from 4140 steel or 416 stainless steel, the muzzle brake has a 1/2-28 thread for universal rifle compatibility and measures 2-5/8" long with a .625" outside diameter.
