The Dead Air Xeno Adaptor is a precision suppressor mounting interface designed for shooters who demand repeatable zero and minimal footprint. Built as the hub component of Dead Air's Xeno mounting system, this adaptor bridges your Xeno muzzle device and suppressor with exacting tolerances and materials engineered for long-range rifles, precision bolt-actions, and duty weapons where durability and consistency matter.

The Xeno system distinguishes itself through thoughtful engineering: its short length and shallow muzzle device seating minimize erosion of suppressor baffles, extending suppressor life while preserving acoustic performance. Unlike deeper-mounting designs, the Xeno keeps the muzzle device positioned forward of the blast chamber, reducing focused heat and carbon buildup that degrades internals over extended shooting sessions. The adaptor itself uses industry-standard 1-3/8-24 (HUB) threads, making it compatible with many quality suppressors already in circulation. Left-hand threads on the muzzle-device interface lock the adaptor to your silencer, preventing accidental unthreading when you break down the system—and letting you verify tension during reinstallation without a torque wrench at the firing line.

Material selection reflects Dead Air's no-compromise approach: nitrided 4140 steel provides hardness and corrosion resistance without the galling and seizing issues common to uncoated 17-4 stainless. Carbon and copper cleanup is genuinely easier, and your threads stay intact after dozens of mount cycles. Generous tooling surfaces—1-1/8" socket and 1.5" hook spanner compatible—remain accessible even with the suppressor fully installed, so you can apply torque or verify tightness without breaking the rig apart mid-range session.

Available in three weights and lengths depending on your caliber and platform, the Xeno Adaptor adds minimal mass and length to your setup while delivering the repeatability and durability that separates field-proven gear from mall-ninja marketing.

Frequently Asked Questions

What suppressors are compatible with the Xeno Adaptor?

The Xeno Adaptor uses industry-standard 1-3/8-24 (HUB) threads on the suppressor-mounting side, making it compatible with many quality suppressors on the market that accept this thread size. Check your suppressor's HUB thread specification to confirm compatibility.

Do I need a specific Xeno muzzle device to use this adaptor?

Yes, the Xeno Adaptor pairs with Dead Air Xeno muzzle devices. The left-hand threads on the adaptor's muzzle-device interface are designed specifically for Xeno muzzle devices.

Will the adaptor stay tight or unthread when I remove the suppressor?

The left-hand threads on the muzzle-device interface are engineered to prevent accidental unthreading when you break down the suppressor. You can verify the mount is still tight when reinstalling on your firearm without needing tools at the gun.

Which Xeno Adaptor variant should I choose?

Dead Air offers three variants: DA455 (1.92 oz, 1.241"), DA457 (1.60 oz, 1.125"), and DA458 (1.44 oz, 1.125"). Variant selection depends on your caliber and platform. Consult Dead Air's compatibility documentation or contact us for guidance matching your rifle.
