The Dead Air Xeno Flash Hider in 5/8x24 is a precision muzzle device engineered for shooters who demand repeatability without compromise. Built as both a standalone flash hider and as the foundation of Dead Air's Xeno suppressor mounting system, it's designed for precision rifle builds where zero retention and minimal added weight matter. If you run a suppressor-equipped rifle and want rock-solid return to zero with every mount and removal, this is the platform that delivers.
What sets the Xeno apart from conventional flash hiders is its role within Dead Air's mounting ecosystem. The shortened length and shallow insertion into a suppressor's blast chamber reduce focused erosion on baffle stacks, extending suppressor life while maintaining acoustic performance. The Xeno Adapter uses industry-standard 1-3/8-24 threads, making it compatible not only with Dead Air's Nomad series but also many other commercially available silencers. Left-handed threads between the flash hider and adapter eliminate the risk of the adapter unthreading from your suppressor during extended firing sessions—and let you verify the mount is still tight each time you install it on your rifle.
Dead Air chose nitrided 4140 steel for its superior hardness and corrosion resistance. Unlike uncoated 17-4 stainless, this material won't gall or seize threads, which means easier cleaning and lower risk of thread damage when removing carbon and copper fouling. Generous tooling surfaces remain accessible even with a suppressor fully installed, so you can apply torque if needed after hundreds or thousands of rounds downrange without disassembly.
Whether you're building a precision long-range rifle, a duty rifle, or a hard-use hunting gun that will wear a suppressor for the long haul, the Xeno Flash Hider combines lightweight design with the durability and repeatability that serious shooters expect from Dead Air.

The Xeno Flash Hider is designed to pair with Dead Air suppressors equipped with a Xeno Adapter. The Xeno Adapter uses industry-standard 1-3/8-24 threads, so it's also compatible with many other commercial silencers that accept that thread size. Always verify compatibility with your specific suppressor model before purchase.
Yes. The Xeno Flash Hider functions as a complete muzzle device on its own. However, its design and reputation are strongest when paired with a compatible suppressor and Xeno Adapter for precision shooting applications.
Left-handed threads on the adapter prevent it from unthreading from your suppressor during normal firing. This also lets you verify the mount is tight by hand each time you install the flash hider on your barrel, without needing to disassemble the suppressor.
Yes. The 4140 steel with QPQ/Black Nitride coating provides high hardness and superior corrosion resistance. Unlike uncoated 17-4 stainless, it resists galling and thread seizure, making it easier to clean and less likely to suffer thread damage from carbon and copper fouling.
