The SilencerCo 3-port Muzzle Brake is designed to redirect a portion of the propellant gases to counter recoil and reduce muzzle climb, enhancing accuracy and control with every shot. Crafted from premium materials and precision-engineered for superior performance, the muzzle brake is the ultimate choice for serious shooters. Each ASR Muzzle Brake comes with a shim set and rocksett for easy application.

The SilencerCo Muzzle Brake has the added benefit of being compatible with the SilencerCo ASR Mount, which you can thread over the top of this 3-port muzzle brake for a quick mount option. With multiple thread and caliber options of muzzle brakes, you can quickly and effectively shoot suppressed on multiple platforms. The ASR mount is one of the best performing suppressor mounting systems available today. See the size chart below to find the correct ASR Mount for your silencer.
