The Dead Air Xeno Xero (brand part no. DA127) is a minimalist taper-mount muzzle device that gives Xeno-compatible suppressors a lightweight, return-to-zero attachment point on 1/2×28-threaded barrels. Dead Air Silencers machines the Xero from 4140 heat-treated alloy steel with a black nitride finish, and its short 1.105-inch length keeps the device shallow in the suppressor’s blast chamber — preserving sound performance while trimming weight. The 9mm bore suits 9mm and smaller projectiles, making it a natural fit for PCCs, SMG-pattern pistols, and light-contour bolt guns. Among Class 3 parts and accessories, the Xero favors shooters who want the lightest possible taper mount for their Xeno-system can.
