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