Dead Air KeyMo GOV HUB Adapter - 1 3/8x24

Upgrade from a direct-thread fixed mount to Keymo fast-attach — with mechanical secondary retention for added security. The Dead Air Keymo GOV HUB Taper Adapter converts any HUB-compatible (1.375x24) Dead Air silencer to Keymo GOV fast-attach mounting, with a mechanical secondary retention feature that adds a positive lock beyond the standard QD interface.

The Dead Air Keymo GOV HUB Taper Adapter is a 1.375x24 HUB-compatible suppressor mounting adapter in 17-4 stainless steel with black nitride and Cerakote finish, featuring a mechanical secondary retention feature and compatibility with all Dead Air Keymo and KeyMicro muzzle brakes, flash hiders, and KeyMo Zero devices.

Three features define the DA428GOVHT's suppressor mounting advantage. Keymo GOV fast-attach mounting replaces a direct-thread fixed mount with a faster, more repeatable QD attachment method — enabling suppressor removal and installation without tools and in a fraction of the time of direct-threading. The HUB Taper interface provides increased surface contact between the suppressor and adapter compared to a standard HUB pattern interface, minimizing micro-movement that contributes to loosening and zero shift during sustained fire. The mechanical secondary retention feature adds a positive lock beyond the standard QD interface, providing an additional layer of security against accidental disengagement under the vibration and recoil of high-volume fire.

Compatible with all Dead Air HUB (1.375x24) taper pattern and HUB pattern silencers. Compatible with all Dead Air Keymo and KeyMicro muzzle devices.

17-4 stainless steel. Black nitride and Cerakote finish. Overall length: 1.670 inches. Weight (HUB mount): 4.30 oz.

Ideal for Dead Air HUB suppressor owners upgrading from direct-thread to Keymo fast-attach, or adding secondary retention to an existing Keymo setup.
