Upgrade your rifle’s muzzle setup with the SilencerCo ASR Muzzle Brake 5/8″-24 for .30 Caliber, a precision-engineered muzzle accessory designed for compatible firearms and SilencerCo Active Spring Retention (ASR) mounting systems.

The SilencerCo ASR Muzzle Brake helps reduce felt recoil and muzzle rise, supporting improved rifle control during repeated shots. Its ASR-compatible design also allows use as part of a compatible suppressor mounting system, offering flexibility for shooters who want a muzzle brake that can serve as both a recoil-management accessory and a suppressor mounting interface.

Featuring 5/8″-24 muzzle threads, this model is intended for compatible .30-caliber rifle barrels. The correct thread pitch and caliber compatibility are essential when selecting a muzzle device, particularly when the brake will be used with a suppressor.
