The Dead Air Armament Xeno Xero DA127 is a lightweight, minimalist 1/2x28 threaded taper-mount muzzle device with a 9mm through bore. It is built for shooters who want a compact Xeno mounting option without the added length or profile of a brake or flash hider.

The Xeno Xero gives compatible suppressors a repeatable taper-mount interface while keeping the host rifle or carbine streamlined. The shorter size reduces how far the muzzle device extends into the suppressor blast chamber, helping reduce overall weight while supporting consistent lock-up and return-to-zero performance.

Minimalist Xeno Mount: The DA127 Xeno Xero is not a muzzle brake or flash hider. It is a compact threaded taper mount for use with Dead Air Xeno adapters and compatible suppressors.

1/2x28 Thread Pitch with 9mm Bore: This DA127 model uses 1/2x28 barrel threads and is bored for 9mm and smaller projectiles. It may be useful for compatible 9mm PCCs, carbines, and other properly threaded hosts where Xeno mounting is desired.

4140 HT Steel and Black Nitride Finish: Dead Air uses heat-treated 4140 alloy steel with a black nitride finish for durability, corrosion resistance, surface hardness, and easier cleaning after suppressor use.

Xeno System Advantages: The Xeno system uses a large taper, left-hand suppressor interface threads, and accessible tool features to support repeatable mounting, hard-use durability, and easier removal.

Important Fitment Note: This DA127 model has 1/2x28 barrel threads and a 9mm bore. Always confirm barrel thread pitch, projectile diameter, suppressor compatibility, Xeno adapter compatibility, and bore alignment before installation or suppressor use.
