Dead Air Silencers Xeno HUB Taper Adapter Black. The Xeno Mounting System still provides hardcore users with the durability youve come to expect from Dead Air. The DA455HT features an upgraded HUB Taper interface that increases surface contact between the suppressor and adapter minimizing the risk of loosening during extended use. It also features an angular difference on the interfacing (HT) shoulder of the adapter to the silencer providing a visual confirmation of proper torque. The shorter length and lockup positioning of the Xeno Mounting System make it shine. How exactly? The Xeno muzzle devices dont 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 futureproof design with consideration for suppressors that have smaller blast chambers across the industry. Plus the adapter uses the industry standard 1.375-24 (HUB) threads making it compatible with many silencers on the market. The Xeno muzzle devices and Xeno Adapter attach together with left handed threads eliminating concerns of the adapter unthreading from your silencer when removed. This also lets you verify your mount is still tight when installing on your firearm. The Xeno System features ample tooling surfaces throughout giving you plenty of room and options. These tool features are accessible even when your suppressor is completely installed.
