The Dead Air Keymo Zero is a quick-detach muzzle device engineered for shooters who want a lightweight, repeatable suppressor mount without the bulk. Designed in 11/16-24 threading for .45 caliber applications, this minimalist mount delivers the speed and consistency you need for tactical, hunting, or range work—whether you're running a single suppressor across multiple uppers or swapping between hosts. The Keymo Zero shrinks its footprint at the muzzle, stepping deeper into the bore with less material in the blast chamber, which translates to quieter sound performance and keeps overall weight down where it matters.
Dead Air engineered this mount to play nice with their full Keymo and Keymicro suppressor ecosystem, so you're building into a system rather than locking yourself into a single can. The 4140 chromium-molybdenum steel, heat-treated and finished in black nitride, handles the punishment of repeated attachment and removal—no carbon-locking, no stuck mounts, just fast, clean cycling. The 3/4-inch wrench and socket feature makes timing and installation straightforward without special tools.
At just over an inch in outside diameter and 1.385 inches long, the Keymo Zero adds minimal signature to your barrel while maintaining the repeatability that makes quick-detach systems worth the investment. If you're serious about suppressor versatility and sound performance in a compact package, this mount deserves a hard look.
