SilencerCo ASR Muzzle Brake — .458 Cal

SilencerCo ASR Muzzle Brake 11/16-24 for .458 Cal - Black

Get real recoil control on your big-bore build with the SilencerCo ASR Muzzle Brake — a purpose-built .458 caliber muzzle device that redirects propellant gases to reduce felt recoil and muzzle climb on heavy-hitting rifle platforms.

This 3-port muzzle brake is engineered specifically for .458 caliber rifles, including .458 SOCOM and other big-bore systems where recoil management genuinely matters. It's compatible with SilencerCo's full ASR mounting system, giving you the same one-hand-on, one-hand-off suppressor attachment and detachment that makes swapping cans between hosts fast and simple. Once shouldered, the locking ring keeps your suppressor from rotating or working itself loose, even under sustained heavy firing.

Built from steel with a durable black Nitride finish, this brake is engineered for long-term reliability and precise manufacturing tolerances — the kind of build quality that lets you maintain and upgrade a hard-hitting rifle with confidence rather than wondering if a cheaper part will hold up. It ships with a shim set and Rocksett for proper alignment and a secure installation.

Whether you're building out a suppressed .458 SOCOM rifle for hunting or tactical use, need genuine recoil reduction on a big-bore platform, or want the convenience of SilencerCo's ASR quick-detach ecosystem on a heavier caliber, this ASR Muzzle Brake gives you the mounting foundation your suppressor setup depends on.
