SilencerCo AC4766 ASR Muzzle Brake 9mm Luger 9/16x24 RH Titanium Black Nitride

The SilencerCo AC4766 ASR Muzzle Brake is a suppressor-ready muzzle device designed for 9mm Luger hosts with a 9/16x24 RH threaded barrel. Its 3-port design redirects a portion of the propellant gases to counter recoil and reduce muzzle climb, sharpening follow-up shot control whether the host is run unsuppressed or paired with a SilencerCo ASR-mount can.

Built from titanium and finished in Black Nitride, the AC4766 is a purpose-built brake for 9mm pistol-caliber hosts in the SilencerCo suppressor ecosystem. Titanium construction paired with the Black Nitride finish gives this brake the corrosion resistance and durability expected of a mount-ready muzzle device.

The AC4766 is part of SilencerCo's ASR muzzle device line and is fully compatible with all SilencerCo ASR-mount suppressors, allowing the shooter to attach a compatible suppressor for suppressed fire and swap back to the bare brake for unsuppressed use. The 9/16x24 RH thread pattern and 9mm orientation make this brake a factory-engineered entry point into the SilencerCo ASR system.
