The Kaw Valley Precision ASR muzzle brake in M14x1 LH thread (brand part no. KVPBRAKEASR10) is a quick-attach brake built to work with SilencerCo ASR (Active Spring Retention) mounting systems. Kaw Valley Precision machines it from 17-4 stainless steel and finishes it in black nitride QPQ. It attaches and detaches without timing or shims, so moving a suppressor between rifles takes seconds.
