The Dead Air Armament Xeno Muzzle Brake for 1/2x28 threads (DA123) is an omnidirectional brake that gives you a lightweight suppressor mounting option with non-negotiable repeatability and a solid return to zero (ideal for precision minded shooters).
The shorter length and lock-up positioning of the Xeno Mount System makes it shine. The Xeno Brake doesn’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 threads, making it not only compatible with their Nomad series, but also many other silencers on the market.
The Xeno Brake and Adapter(NOT Included) mate 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. Both the Brake and Adapter feature ample tooling surfaces, giving you plenty of room and options. These tool features are accessible even when your suppressor is completely installed.
Their 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. 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.
