The Dead Air Xeno Adapter in the P-Series configuration (brand part no. DA457) pairs with Xeno muzzle devices for a lightweight suppressor mounting option with repeatable lock-up and solid return to zero. Dead Air Silencers positions the Xeno system’s lock-up so the muzzle device does not sit deep in the blast chamber, minimizing focused baffle erosion while preserving sound performance, and the adapter’s industry-standard HUB threads (1-3/8×24) fit many silencers on the market. Left-hand threads keep the adapter from unthreading with the muzzle device during removal, and ample tooling surfaces stay accessible even with the suppressor installed. Among Class 3 parts and accessories, this adapter favors precision shooters who want a short, durable quick-mount system.
