The Dead Air Xeno Adapter HUB Taper (DA455HT) is a precision suppressor mounting adapter built for shooters who demand rock-solid repeatability and zero shift. If you're running a quality suppressor and want a mount that stays tight through extended shooting sessions, this lightweight adapter brings Dead Air's proven durability to the Xeno Mounting System—a design that prioritizes both performance and long-term suppressor life.
What sets the Xeno Adapter apart is its engineering philosophy: the shortened design positions your suppressor shallower in the blast chamber, which reduces focused erosion on baffles and extends suppressor longevity while maintaining sound performance. The upgraded HUB Taper interface increases surface contact between adapter and silencer, minimizing the risk of loosening over time. An angular difference on the shoulder of the adapter provides visual confirmation of proper torque—a simple but effective way to verify your mount is tight before or after removal.
The Xeno system uses left-handed threads between the muzzle device and adapter, eliminating the risk of the adapter unthreading from your silencer when you remove the weapon. This also lets you check that your mount is secure whenever you install on your firearm. The standard 1.375-24 (HUB) thread pattern makes it compatible with most Dead Air HUB and HUB-taper silencers on the market, and the design is future-proof enough to work with smaller blast chambers across the industry. Ample tooling surfaces throughout the adapter remain accessible even with your suppressor fully installed, giving you flexibility whether you're in the field or at the bench.
Built from 4140 HT QPQ Black Nitride, the DA455HT is tough enough for serious use. The shorter length and precision lockup of the Xeno system make it ideal for shooters who refuse to compromise on consistency—whether you're dialing in a precision rifle or running regular suppressed fire at the range.
| Product Name | Xeno Adapter HUB Taper |
| Model Number | DA455HT |
| Material | 4140 HT QPQ Black Nitride |
| Thread Pattern | 1.375-24 (HUB) |
| Tool Features | 1-1/8 Socket and 1.5 Hook Spanner compatible |
| Suppressor Compatibility | All Dead Air HUB (1 3/8-24) taper pattern and HUB pattern silencers |

The DA455HT is compatible with all Dead Air suppressors that use the HUB (1 3/8-24) thread pattern or HUB taper pattern, making it a versatile choice across Dead Air's suppressor lineup. The standard 1.375-24 threading also makes it compatible with many other HUB-pattern silencers on the market.
The adapter and muzzle device attach with left-handed threads, which prevents the adapter from accidentally unthreading from your suppressor when you remove the weapon. This design also lets you quickly verify your mount is still tight whenever you install the adapter on your firearm.
No. The shortened design and shallow positioning in the blast chamber actually reduce focused erosion on your suppressor's baffles, helping extend its lifespan. The upgraded HUB Taper interface minimizes the risk of loosening, which protects both the adapter and silencer from damage due to movement.
The adapter features tooling surfaces compatible with a 1-1/8 Socket and 1.5 Hook Spanner. These tool features remain accessible even when your suppressor is completely installed, giving you flexibility in how you service or verify your mount.
