The Dead Air Xeno Xero Taper Mount (brand part number DA127) is a threaded taper mount machined from 4140 heat-treated alloy steel and threaded 1/2-28 to bore a 9mm and smaller projectile path. 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. Its shorter profile decreases how far it enters the blast chamber, which maximizes sound performance while minimizing overall weight at the muzzle. The Xeno Xero is compatible with every Dead Air Xeno Adapter, making it a flexible foundation for building out a suppressor host.
