- HUXWRX/OSS Suppressors is excited and proud to offer a line of muzzle devices specifically designed to be compatible with their suppressors. This particular muzzle device is a muzzle brake which is designed to reduce felt recoil when the suppressor is not in use. When the compatible QD suppressor is installed it works as the first baffle in a unique system which directs and diverts gas differently than other suppressor manufacturers.
