Dead Air – Xeno Xero Lightweight Taper Mount Muzzle Device

The Dead Air Xeno Xero is a lightweight, minimalist threaded taper mount muzzle device designed for shooters who demand absolute repeatability, durability, and precision. Built around the proven Dead Air Xeno mounting system, the Xero delivers a rock-solid return to zero while reducing overall weight and maximizing suppressor sound performance.

Its shortened profile minimizes intrusion into the blast chamber, helping optimize suppressor efficiency while maintaining the rugged performance expected from Dead Air products. A large precision-machined taper, left-hand threads, and accessible tool features work together to prevent carbon lock and ensure consistent alignment under hard use.

Compatible with all Dead Air Xeno Adapters, the Xeno Xero is engineered for precision shooting, duty rifles, and suppressor-ready builds where reliability and repeatability matter most.
