The Dead Air Xeno A1 Flash Hider in 5/8-24 (Dead Air part no. DA122) works as a stand-alone muzzle device and pairs with a Xeno adapter for a lightweight suppressor mount with solid return to zero. Dead Air machines it from nitrided 4140 steel, and it mates to the adapter with left-hand threads so the adapter cannot unthread from the suppressor when you remove it. The short Xeno lock-up keeps the device from sitting deep in the blast chamber, which minimizes baffle erosion. This is the 5/8-24 version, with a .30 caliber bore. The Xeno adapter is sold separately.
