The Dead Air Keymo Zero 5/8-24 .45 Cal is a quick-detach muzzle brake and suppressor mount engineered for shooters running .45 ACP and other large-bore platforms. Built on Dead Air's proven KeyMo system, this lightweight adapter gives you reliable, repeatable attachment and detachment without carbon lock-up—critical for field use where you need to swap suppressors or remove the can without fighting seized components. If you're running a Dead Air suppressor with KeyMo or KeyMicro adapter compatibility, the Zero gives you a minimalist mounting solution that doesn't sacrifice durability.
The design philosophy here is straightforward: keep the mass down and the performance up. The compact profile minimizes intrusion into the suppressor's blast chamber, which translates to better sound performance and less overall system weight—practical advantages whether you're hunting, running suppressed pistol drills, or building a precision .45 bolt gun. The 4140 chromium-molybdenum steel, heat-treated and finished in black nitride, is built to handle repeated mounting cycles and long-term use without degradation.
Installation is straightforward: the muzzle device features a 3/4-inch wrench and socket interface, so timing and torque are repeatable across barrels. If you've already standardized on Dead Air's KeyMo ecosystem, this mount slots seamlessly into your suppressor collection and lets you move cans between hosts without proprietary tool headaches.
