Dead Air DA457 Xeno Adapter | 1-3/8-24 HUB | Black Nitride

The Dead Air Xeno Adapter (DA457) is a lightweight, repeatable mounting solution for Xeno muzzle devices and P‑Series suppressors. Constructed from nitrided 4140 HT steel, the adapter is designed to reduce focused baffle erosion and provide consistent return to zero. It uses industry-standard 1-3/8-24 (HUB) left-handed threads and is compatible with several Dead Air P-Series silencers.

Typical applications include precision shooting where repeatable mounting and minimal baffle wear are priorities, and competition or range use where a compact, low‑profile mounting system is desired.
