he Xeno Pistol Wee Brake is the latest addition to our line of Xeno muzzle devices. Featuring a 9mm bore size in all thread pitch variations, the Xeno Pistol Wee Brake was designed as a QD mounting option with your pistol caliber Sub-Guns in mind. Pair the Xeno Pistol Wee Brake with the appropriate Xeno Adapter to use on your Wolfman, Ghost, Primal, Nomad, Sierra 5, and many more! The shortened length of Xeno Muzzle devices is not only small in weight and length profile, but it also supports a more future-proof design with a heavy consideration for suppressors with smaller blast chambers across the industry.
