SilencerCo AC857 ASR 3-Port Muzzle Brake 338 Cal 5/8x24 Black Steel

The SilencerCo AC857 ASR Muzzle Brake is a 3-port recoil-mitigation device purpose-built for 338 caliber rifles with 5/8x24 threads. Machined from durable steel and finished in a corrosion-resistant black coating, this muzzle brake redirects a portion of the propellant gases to counter recoil and reduce muzzle climb, enhancing follow-up shot accuracy.

Engineered as part of SilencerCo's Active Retention System (ASR) family, the AC857 is fully compatible with all SilencerCo ASR Mounts. The system allows for quick one-hand-on, one-hand-off attachment and detachment of your suppressor without the need for tools or shims, making the transition between suppressed and unsuppressed fire faster and more reliable in the field.

Designed specifically for big-bore rifles in 338 caliber with 5/8x24 thread pitch, the AC857 installs directly to the barrel and provides a secure mounting interface for any SilencerCo ASR-equipped suppressor. Whether you are running a long-range precision build, hunting rifle, or tactical 338 platform, this muzzle brake gives you both functional recoil control and a seamless path to suppression.
