Dead Air XEMAX Adapter DA456HT | HUB 1-3/8×24

The Dead Air XEMAX Adapter DA456HT is a HUB-pattern 1 3/8-24 adapter designed for large-bore suppressor systems. It employs Xeno Mounting Technology with a self-aligning taper for concentric bore alignment and consistent repeatability. The adapter is specified as being made from 4140HT chromium-molybdenum heat-treated steel with a black nitride finish and is intended for use with Dead Air Nomax 33 and Primal silencers. XEMAX components are designed to pair with Xemax muzzle brakes and are not cross-compatible with Xeno devices.

Common applications include precision long-range bolt-action work with large-caliber rifles and use on big-bore lever-action or MSR platforms for hunting and heavy-caliber target shooting.
