The Dead Air Xeno Xero Brake (brand part number DA135) is a 9mm muzzle device machined from 4140 heat-treated alloy steel, threaded 9/16×24 RH, with a compact 1.105-inch overall length and 0.99-inch diameter. Dead Air built the Xeno Xero as a lightweight, minimalist mounting option that still delivers non-negotiable repeatability and a solid return to zero shot after shot, with the same durability shooters expect from a Dead Air mount. Its shorter size decreases how far it enters the blast chamber, maximizing sound performance and minimizing overall weight. Finished in black, the Xeno Xero is compatible with every Dead Air Xeno Adapter.
