Works with all Xeno muzzle devices.

Combine a Xeno muzzle device with this Xeno Adapter for a lightweight suppressor mounting option with non-negotiable repeatability and solid return to zero — ideal for precision-minded shooters. The Xeno Mounting System still provides you hardcore users the durability you’ve come to expect from Dead Air.

The shorter length and lock-up positioning of the Xeno Mounting System makes it shine. How exactly? The Xeno muzzle devices don’t sit deep into the blast chamber. This minimizes focused erosion on your baffles, prolonging suppressor life while maximizing sound performance.

The shortened length also supports a more future-proof design with a heavy consideration for suppressors with smaller blast chambers across the industry. Plus, the Adapter uses the industry standard 1-3/8-24 (HUB) threads, making it compatible many silencers on the market.

The Xeno muzzle devices and Xeno Adapter attach together with left-handed threads, eliminating your worries of the adapter unthreading from your silencer when removed. This also lets you verify your mount is still tight when installing on your firearm.

The Xeno System features ample tooling surfaces throughout, giving you plenty of room and options. These tool features are accessible even when your suppressor is completely installed. This is for you folks that don’t remove your silencer for hundreds or thousands of rounds fired and may need that extra “torque.”

Our material of choice is nitrided 4140 steel for hardness and corrosion resistance. The bonus is that it won’t gall your threads as is common with the uncoated 17-4 products out there. It’s no fun having your mount drilled from the back of your suppressor while you’re biting your nails hoping it can be salvaged. Nitrided 4140 is just tough. Scouring off carbon and copper deposits is not only easier, but you’re also less likely to damage your threads.

For those desiring a mounting system that offers insane repeatability and durability, with very little length and weight added to your firearm, the Xeno is what you’re after.


To mount your suppressor using a Xeno adapter your host firearm must be equipped with a Xeno muzzle device (sold separately).
