The Dead Air Lazarus 6 Xeno FDE suppressor is the Flat Dark Earth, Xeno-mount version of Dead Air’s hard-use 5.56 and 6mm ARC silencer (Dead Air part no. LZ6XNFDE). Its body is 3D-printed from Haynes 282, a nickel-based superalloy that Dead Air chose for extreme-duty use. Dead Air rates the can full-auto for 5.56 NATO and 6mm ARC, and the Triskelion Gas Management System keeps back pressure low. The Xeno adapter holds overall length to 5.89 inches and weight to 16.5 ounces. Pair it with an FDE rifle, or choose it for a Cerakote finish that holds up to heavy firing schedules.
