Dead Air Armament – Xeno Pistol Wee Brake QD Muzzle Device

The Dead Air Armament Xeno Pistol Wee Brake is a compact, precision-engineered QD muzzle device designed specifically for pistol-caliber sub-guns and modern suppressor setups. Built around the rugged Dead Air Xeno mounting system, this Wee Brake delivers exceptional repeatability, durability, and thread security with minimal added length or weight.

Featuring a 9mm bore across all thread pitch variants, the Xeno Pistol Wee Brake pairs seamlessly with the appropriate Xeno Adapter for use on popular suppressors including the Wolfman, Ghost, Primal, Nomad, Sierra 5, and more. Its shortened profile is optimized for suppressors with smaller blast chambers, making it a future-proof mounting solution for evolving suppressor designs.

Constructed from nitrided 4140 steel, this muzzle device offers superior hardness, corrosion resistance, and reduced thread galling compared to uncoated 17-4 stainless alternatives. The nitrided finish also makes carbon and copper fouling easier to remove, helping protect both your barrel threads and suppressor mounting surfaces over time.

The Xeno system’s large taper interface, left-hand threads, and accessible tool features work together to ensure rock-solid lockup, consistent return to zero, and reliable performance under hard use. For shooters seeking a lightweight, low-profile QD mounting option that prioritizes precision and long-term durability, the Xeno Pistol Wee Brake delivers.
