The Dead Air Xeno Adapter Legacy (brand part number DA458) is machined from 4140 heat-treated alloy steel and finished in black nitride for a mounting component that holds up to repeated suppressor mounting and removal. At just 1.125 inches, it adds minimal length to your muzzle while keeping you compatible with Dead Air’s established Xeno mounting hardware. The Legacy designation identifies it as a match for Dead Air’s earlier-generation Xeno components, so it’s the right pick if you’re already running that mounting system. This is a straightforward, durable adapter for shooters building out or maintaining a Xeno-based suppressor setup.
