Dead Air Xeno Adapter | 1-3/8-24 HUB | DA455

The Dead Air Xeno Adapter (MFG# DA455) provides a compact, repeatable mounting solution for HUB-based silencers using 1-3/8-24 threads. Built from nitrided 4140 steel, the adapter is intended to minimize baffle erosion by reducing how deep muzzle devices sit in the blast chamber while keeping overall length and weight low. The product is purpose-built for precision-minded shooters who want consistent return-to-zero and durable hardware in suppressed rifle builds.

Typical applications include precision/target rifle builds and suppressor-equipped hunting setups where reduced length and repeatability are priorities. Xeno muzzle devices are sold separately.

Product Specifications

• UPC is 810128160254.

The Xeno Adapter is a purpose-driven component for those prioritizing low added length, repeatable lock-up, and durable materials in suppressed rifle systems. It provides ample tooling surfaces for installation and maintenance even when a suppressor is fully assembled, and its shorter mount geometry helps limit focused erosion on baffles compared with deeper-mating muzzle devices.

For users building a compact, repeatable suppressor mounting solution—especially in precision or hunting-oriented rifle platforms—the Xeno Adapter offers a durable, low-profile option that integrates with existing HUB silencers and Dead Air Xeno muzzle devices (sold separately).

Owners and builders frequently note its reliable return-to-zero and robust construction as key strengths.
