The Kaw Valley Precision Muzzle Brake for ASR in 5/8×24 is a stainless steel brake designed to work with ASR (Active Spring Retention) mounting systems (brand part no. KVPBRAKEASR02). Kaw Valley Precision machines it from 17-4 stainless and finishes it in black nitride QPQ. It attaches and detaches quickly without timing or shims, and its bore accepts any caliber. It is a direct fit for shooters who already run an ASR-mount suppressor and need a matching muzzle device for a 5/8×24 barrel.
