XENO SYSTEM ONLY – REQUIRES A DEAD AIR XENO ADAPTER / XENO-COMPATIBLE SUPPRESSOR FOR QD FUNCTION.

The Dead Air Xeno Pistol Wee Brake (DA125) is a compact QD muzzle brake and suppressor mount designed for use with the Dead Air Xeno mounting system. Featuring a 1/2x28 thread pitch and a generous 9mm bore aperture, this muzzle device is optimized for PCCs, subguns, and fixed-barrel hosts requiring a lightweight and highly concentric suppressor mounting solution.

Engineered as part of the Dead Air Xeno taper mount ecosystem, the Wee Brake provides a secure, repeatable lockup that resists loosening under fire while maintaining minimal point-of-impact shift. Its compact “wee brake” profile reduces muzzle rise without adding excessive length or weight to the host firearm.

Constructed from hardened steel with a corrosion-resistant black nitride finish, the DA125 is built for high round-count use in demanding suppressed shooting environments. The 9mm bore across Xeno pistol wee brake variants ensures safe clearance for pistol-caliber and many intermediate cartridges when properly aligned.

IMPORTANT: This muzzle device is not compatible with KeyMo, ASR, or direct-thread suppressor systems. Always verify thread pitch (1/2x28), suppressor mount system (Xeno), and alignment prior to suppressor use.
