Kaw Valley Precision Muzzle Brake for ASR M14x1 LH Black

The Kaw Valley Precision Muzzle Brake for ASR is a precision-machined muzzle device engineered to mate directly with SilencerCo ASR (Active Spring Retention) mounting systems. Cut from 17-4 stainless steel and finished in a corrosion-resistant Black Nitride QPQ coating, this brake lets a shooter move quickly between suppressed and unsuppressed fire without tools or repeated thread changes at the suppressor interface.

This variant is threaded M14x1 LH (left-hand) for hosts that require that pitch and handedness, and the compact 2.05" overall length keeps the device well within standard rifle contours. The .500 bore is rated for any caliber, so the same brake can be installed across multiple rifles in your safe and serves equally well as a stand-alone recoil-mitigating muzzle brake or as the dedicated mounting point for an ASR-compatible suppressor.

Backed by Kaw Valley Precision's reputation for tight tolerances and durable finishes, the brake ships ready to install on any rifle threaded M14x1 LH. When you're ready to run suppressed, the ASR-compatible shoulder seats directly into any SilencerCo ASR muzzle mount or compatible adapter for fast, repeatable attachment.
