The Dead Air Xeno Xero in .578-28 is a threaded taper mount that gives a lightweight, minimalist mounting option with solid return to zero (brand part no. DA144). Dead Air Silencers makes it compatible with all Dead Air Xeno adapters. The shorter body sits less deeply in the blast chamber, which keeps weight down and helps sound performance. This is the .578-28 thread pitch with a .458 through bore, so it fits .45 caliber and smaller projectiles. The Xeno system uses left-hand mating threads and has accessible tool features for hard use.
