Dead Air
The Dead Air Xeno DA128 is a precision-engineered muzzle device built for .45-caliber rifles and pistols that demand repeatable accuracy without compromise. This 5/8-24 threaded taper mount delivers the minimalist mounting platform Dead Air is known for, engineered to return to zero shot after shot while keeping weight and footprint minimal. If you're running a .45 ACP upper, .458 SOCOM, or any .45-caliber platform where precision and reliability matter, the Xeno DA128 gives you a dead-solid foundation for mounting suppressors or other Dead Air components.
The Xeno DA128's compact 1.105-inch length is intentional: a shorter entrance into the blast chamber means better sound performance from your suppressor while shaving unnecessary weight off the muzzle. At just 1.50 ounces, it won't throw off your balance or shift your point of impact. The 4140 HT alloy steel construction with black nitride finish handles hard use without flinching—whether you're running suppressed precision shots downrange or pushing it in the field. The left-hand threads and accessible 3/4-inch wrench feature make installation and removal straightforward without fumbling.
Build your Dead Air Xeno system around this mount: it's compatible with all Dead Air Xeno Adapters, so you can configure the suppressor stack that fits your mission. The large taper and proven Xeno design philosophy mean you're not sacrificing anything for the compact footprint. This is the kind of muzzle device that earns its place on a rifle that sees real use.
