Dead Air DA455HT Xeno Adapter | 1 3/8-24

The Dead Air Xeno Adapter DA455HT is a HUB-mount adapter engineered for use with HUB-based silencers. It provides a 1 3/8×24 threaded interface and a HUB Taper connection finished in nitride. The adapter’s upgraded HUB Taper increases surface contact between the suppressor and adapter to reduce the chance of loosening during extended use. An angular HT shoulder gives a visible cue to confirm proper torque at installation.
