Xeno Adapter for HUB-based silencers with 1-3/8-24 threads. Constructed from nitrided 4140 steel for durability and corrosion resistance. Designed for repeatable, low-profile suppressor mounting. Xeno muzzle devices sold separately.
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
Model designation is Xeno Adapter designed for HUB-style mounts.
Thread specification is 1-3/8-24 (HUB) for compatibility with many HUB silencers.
Constructed from nitrided 4140 steel for hardness and corrosion resistance.
Finish is Black Nitride to reduce surface wear and galling.
Overall dimensions are approximately 1.75 x 1.85 x 4.45 inches as provided by the manufacturer.
Package dimensions list a length of 4.4500 inches, a width of 1.8500 inches, and a height of 1.7500 inches.
Outside diameter is listed as 1.55 inches in product attributes.
Item weight is listed as 1.95 oz.
Product type is listed as Adaptor and is intended for HUB-based suppressor mounting systems.
Additional compatibility notes list it as fitting NOMAD/SC Omega silencers and using a Key Mount FH/MB.
The adapter features left-handed threads where it mates to Xeno muzzle devices to reduce the risk of unthreading from the silencer during removal.
Direct shipment to California is listed as restricted (no direct ship to California) by the supplier.
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.
