The DeadAir Xeno Flash Hider with 4140 stainless steel material; black nitride finish; and 1/2-28 thread pattern.
The Xeno Flash Hider really shines when paired with a Xeno Adapter equipped suppressor, but also works superbly as a standalone muzzle device.
Ideal for precision-minded shooters, this product offers a lightweight suppressor mounting option with non-negotiable repeatability and a solid return to zero, while still providing the expected durability for hardcore shooters.
Now available at Mister Guns, the Dead Air Xeno features a shorter length and lock-up positioning that sets it apart. The Xeno Flash Hider doesn’t sit deep into the blast chamber; and this minimizes focused erosion on your baffles as well as prolongs suppressor life, all the while maximizing sound performance.
The Xeno Flash Hider and Adapter 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 Flash Hider and Adapter offer ample tooling surfaces, giving you plenty of room and options, and these tool features are accessible even when your suppressor is completely installed.
This Dead Air Xeno Flash Hider for sale is made of nitrided 4140 steel for hardness and corrosion resistance. The benefit of the nitride finish is that this item won’t gall your threads as is common with the uncoated 17-4 products out there.
The Xeno system overall takes a simple design and maximizes all the variables in the shooter’s favor. All of the features, from the large taper, the left-hand threads, to the accessible tool features, provide the optimal platform for precision shooting while still being capable of hard use.
