The SilencerCo ASR Muzzle Brake (AC858) provides a rock-solid mounting solution for your SilencerCo ASR-equipped suppressor. Designed for 338 caliber rifles, this muzzle brake threads onto barrels with 3/4"-24 TPI pattern and enables quick, tool-free attachment and removal of compatible ASR flash hiders, muzzle brakes, or brake/suppressor combo devices.

Constructed from durable black steel, this muzzle brake features a three-port design that helps reduce muzzle rise during rapid fire. The included shim set allows you to achieve proper alignment and timing on your specific rifle platform for optimal performance.

This muzzle brake is compatible with the Harvester 338 platform and comes standard with many SilencerCo rifle packages. It serves as the interface between your rifle barrel and ASR-compatible SilencerCo accessories.
