The Dead Air Xeno Xero in 5/8-32 (Dead Air part no. DA146) is a threaded taper muzzle mount that gives a Xeno-compatible silencer a light, repeatable connection to the host barrel. The shorter body enters the blast chamber less, which Dead Air uses to keep weight down and sound performance up. Its through bore is sized for .45 caliber and smaller projectiles, so it suits pistol-caliber hosts threaded 5/8-32. Left-hand threads on the taper side mate with Dead Air Xeno adapters. It is a straightforward pick for shooters who want a minimal, hard-use mount.

Key Specifications

• The host thread is 5/8-32, so check your barrel before ordering because the mount only fits that pitch.
• The through bore fits .458 and smaller projectiles, which Dead Air lists as .45 caliber and under for this thread pitch.
• Material is 4140 heat-treated alloy steel, a tough base for a mount that stays on the barrel.
• The finish is black nitride, a hard coating that protects the steel.
• Length is 1.105 inches, short enough to keep the suppressor close to the muzzle.
• Outside diameter is 0.99 inch, a slim profile for a muzzle mount.
• Weight is 1.60 ounces, which keeps the front end of the host light.
• The tool feature is a 3/4-inch wrench flat, giving you a clean surface to torque the mount against.
• Taper-side threads are left-hand, which lets you confirm the mount is still tight when installing on the firearm.
• It works with all Dead Air Xeno adapters, so one mount can move between compatible silencers.
