The Dead Air Xeno Pistol Wee Brake (brand part number DA126) is a compact 9mm muzzle device machined from 4140 heat-treated alloy steel, finished in Black Nitride, and threaded 5/8×24. Dead Air designed the Wee Brake as a quick-detach mounting option built specifically with pistol-caliber sub-guns in mind, and it is the newest addition to the Xeno family of muzzle devices. Paired with the appropriate Xeno Adapter, it mounts suppressors including the Wolfman, Ghost, Primal, Nomad, and Sierra 5, among others. It gives 9mm pistol-caliber carbine and sub-gun owners a small, purpose-built brake that is ready for a Xeno-adapted can whenever they add one.
