SilencerCo ASR Muzzle Brake | 11/16×24 | AC1961

The SilencerCo ASR Muzzle Brake AC1961 is an ASR-compatible muzzle device engineered for rapid one-hand attachment and detachment using SilencerCo’s ASR mounting system. The design integrates a three-prong flash-hider form factor with patent-pending resonance suppression to reduce the tuning-fork effect found in some competing 3-prong devices. A three-port brake geometry redirects gases to reduce felt recoil and muzzle climb, aiding follow-up shot control for heavy-caliber platforms.

This muzzle brake is commonly listed for large-caliber use in product details (including references to .458 SOCOM) and is intended for recoil management on large-bore rifles and for controlled, high-recoil range use.
