Dead AirDead Air Sierra-5 XM (Xeno) — 5.56mm Hard-Use Rifle Suppressor
The Dead Air Sierra-5 XM (Xeno) 5.56mm is a compact, hard-use rifle suppressor that keeps your setup lighter and shorter while still delivering serious durability—built with welded Cobalt 6 (Stellite) baffles inside a 17-4PH stainless outer tube and finished in high-temp black Cerakote. It’s HUB 1.375x24 compatible, rated for 5.56 NATO/.223 and 224 Valkyrie (2200+ ft-lb class), and is full-auto rated with no minimum barrel length restrictions, making it a true “run it hard” 5.56 can. This version ships with the Xeno mounting system (lightweight, repeatable QD) and typically includes the Xeno adapter plus a 1/2x28 Xeno flash hider mount, coming in at 1.5" diameter, 4.87" body length / 5.72" with Xeno, and 13.3 oz with the Xeno setup.
