Helps Your .22 Conversion AR-15 Run Reliably

Enhances the reliability of .22 conversion AR-15 rifles by increasing back pressure to help cycle the bolt while also decreasing felt recoil. Easily threads onto any muzzle with ½"-28 tpi threads, and machined flats let you use any standard wrench to tighten it on. Three holes near the brake’s muzzle may be aligned in any direction. Not a suppressor; does not reduce sound. Expansion chamber is designed for .22 Long Rifle only; using with .223 or 5.56 ammunition will create a safety hazard.
