The Micro-Brake stabilizes the muzzle shot-to-shot when the silencer is not installed, reducing muzzle flip and felt recoil. It also provides a barrier between the muzzle blast and the blast baffle of the silencer. Timing the Micro-Brake could not be easier. Once the silencer mount is attached to the barrel, the Micro-Brake is added with the provided crush washer. Simply turn the brake on the crush washer until the ports are timed in the desired orientation.
