The SIG Sauer CQB Muzzle Brake muzzle device reduces felt recoil when the SIG Sauer suppressor is not attached. This muzzle brake technically does require timing but doing so really could not be easier. Using the supplied crush washer, simply turn the muzzle brake on the crush washer until the ports are timed to your preferred orientation.
