The Dead Air Xeno Adapter Legacy (brand part no. DA458) is the Xeno mounting adapter for suppressors with a legacy pistol socket, such as SiCo and Rugged. Machined from 4140 heat-treated steel and finished in black nitride, it holds up to repeated mounting and removal. Dead Air gives it a short, 1.125-inch body and a lock-up position that keeps Xeno muzzle devices from sitting deep in the blast chamber. Xeno muzzle devices are sold separately.

Key Specifications

• It fits the Legacy pistol socket that Dead Air lists for SiCo, Rugged and similar suppressors, so it is the Xeno option for those silencers.
• Weight is 1.44 ounces, a minimal addition to the back end of the suppressor.
• Overall length is 1.125 inches, short enough that the Xeno system adds very little length.
• The material is 4140 heat-treated alloy steel, chosen for hardness and strength.
• The finish is QPQ black nitride, which resists corrosion and wear and does not gall threads the way uncoated 17-4 can.
• Tool features accept a 1-1/8 inch socket or a 1.5 inch hook spanner, so it can be torqued on with common tools.
• The left-hand threads on the mating surface keep the adapter from unthreading from the suppressor when the muzzle device comes off.
• The lock-up position keeps Xeno muzzle devices out of the deep blast chamber, which minimizes focused erosion on the baffles.
• The taper lock-up is built for repeatability and a solid return to zero, a priority for precision-minded shooters.
