Dead Air Xeno Flash Hider

DEAD AIR XENO A1 FLASH HIDER

The Dead Air Xeno A1 Flash Hider is the foundation of Dead Air's Xeno taper-mount system. It looks like a standard A1 birdcage, but built into it are the precision threads that serve as the other half of the Xeno mount interface. Pair it with the Dead Air Xeno Adapter, and you get a lightweight suppressor mounting solution with consistent return to zero and no timing required.

CAPITOL ARMORY'S OPINION

The Xeno system is engineered for shooters who demand repeatable precision without adding unnecessary weight or length. The flash hider's shorter lock-up positioning keeps it sitting shallow in the blast chamber, which reduces focused baffle erosion and extends suppressor service life. Left-hand locking threads between the flash hider and adapter prevent the adapter from unthreading during suppressor removal, and allow you to verify the mount is fully seated during installation. The 3/4-inch wrench feature remains accessible even with a suppressor fully installed, so you can torque the mount without breaking down your setup.
