Dead Air Xeno Pistol Wee Brake | 9mm | 5/8×24

The Dead Air Xeno Pistol Wee Brake is a compact muzzle device engineered for pistol-caliber platforms and designed to serve as a QD mounting option when used with the appropriate Xeno adapter. It features a 9mm bore in supported thread variations and is manufactured from nitrided 4140 HT alloy steel for improved surface hardness and corrosion resistance. The shortened profile minimizes added length and weight while supporting suppressors with smaller blast chambers. Typical applications include pistol-caliber carbine (PCC) builds and range/practice use with QD-capable suppressors.
