Sco Asr Mb Single Port 1/2"x28 9mm

The SilencerCo ASR MB Single Port 1/2"x28 9mm muzzle brake is a precision-engineered recoil management component designed for suppressed shooting with the SilencerCo ASR mounting ecosystem. This single-port muzzle brake effectively reduces felt recoil and muzzle climb through controlled port geometry, enabling faster target reacquisition and improved shot placement during both patrol duty and range training. The 1/2"x28 threading accommodates standard 9mm platforms, making it a versatile choice for operators running suppressed duty carbines or compact duty weapons.

The ASR mounting system delivers one-hand-on, one-hand-off attachment and detachment without tools, critical for rapid suppressor changes in field conditions. Each brake ships with a shim set for timing accuracy and Rocksett threadlocker for secure installation. The compact 3.75-inch length and 0.25-pound weight minimize added length to the muzzle while maintaining robust recoil characteristics. This brake integrates seamlessly with all SilencerCo ASR mounts, including those on the Omega 300, Chimera 300, Saker ASR, and Specwar suppressor families—standard equipment across federal, state, and local tactical teams.

Operators running suppressed duty weapons in 9mm benefit from the ASR system's reliability and interchangeability. The single-port design manages the lower impulse signature of 9mm subsonic ammunition while maintaining control of transonic loads. This muzzle brake is purpose-built for shooters who need repeatable suppressor indexing, quick changes between suppressed and unsuppressed configurations, and the accuracy advantage that comes from predictable recoil behavior during rapid-fire sequences. Whether mounted on a patrol rifle, close-quarters weapon, or training carbine, the ASR MB delivers consistent performance across mission profiles.
