The Dead Air Xeno Muzzle Brake in 1/2x28 thread pitch is a precision-focused brake that works equally well as a standalone recoil device or as the foundation of Dead Air's modular suppressor-mounting system. Built from nitrided 4140 steel, it's engineered for shooters who demand zero-shift repeatability, durability under sustained use, and minimal footprint on the barrel. The Xeno's shortened length and high-positioned lock-up geometry set it apart from conventional brakes—it sits proud of the suppressor's blast chamber, which reduces focused erosion of baffle stacks and extends suppressor service life.
The real power of this muzzle brake emerges when paired with Xeno Adapter–equipped suppressors. The brake mates to the adapter via left-hand threads, which means the adapter won't back off your silencer during firing—and you can verify your mount is still tight simply by attempting to rotate the brake. The system uses industry-standard 1-3/8-24 threads on the adapter, making it compatible not only with Dead Air's Nomad series but with many other suppressors on the market. Both brake and adapter feature generous tool surfaces that remain accessible even with a suppressor fully installed, so you can apply torque after hundreds or thousands of rounds if needed.
Nitrided 4140 steel resists corrosion and avoids the thread-galling problems common to uncoated 17-4 alternatives. Carbon and copper fouling comes off cleanly, and your threads stay protected against damage during cleaning. The 1/2x28 threading fits a broad range of precision rifle platforms. Whether you're running this brake standalone for range work or integrating it into a suppressed precision setup, Dead Air's design philosophy favors shooters who won't compromise on repeatability or durability.

Yes. The Xeno Adapter uses industry-standard 1-3/8-24 threads, making it compatible with Nomad suppressors and many other silencers that accept that thread pitch. Verify your specific suppressor's compatibility before purchasing.
No. The Xeno Brake and Adapter connect via left-hand threads, which prevents the adapter from unthreading when you fire. You can also verify your mount is still tight by attempting to rotate the brake—no tools required.
Yes. Both the brake and adapter feature ample tooling surfaces that remain accessible even with a suppressor completely installed, allowing you to re-torque the mount after extended shooting sessions if needed.
The 1/2x28 Xeno Brake is chambered for .30 caliber. Verify bore diameter compatibility with your specific rifle before installation.
