The Dead Air DA143 Xeno Xero is a precision 9mm suppressor mount designed for shooters who demand exact fit and reliable performance. Built from 4140 heat-treated alloy steel, this adapter threads directly onto 9/16x24 right-hand host barrels, providing a rock-solid connection between your suppressor and firearm. Whether you're running a dedicated 9mm host or swapping suppressors across multiple guns, this precision interface ensures consistent zero and repeatable accuracy range session after range session.
Dead Air's engineering focuses on durability and repeatability—qualities that matter when you're stacking precision shots at distance or running suppressed drills on the range. The compact 1.105" overall length and 0.99" diameter keep the profile tight while the 4140 HT steel handles the stress of repeated mounting cycles without creep or play. This is the kind of component that belongs in a rifle system built to last, where every connection counts.
If you're building or upgrading a 9mm shooting platform, the Xeno Xero delivers the precision interface modern suppressors demand. It's straightforward, well-made, and built to work. That's the Dead Air standard.
