Dead Air DA012 Detent Ring for KeyMo & KeyMicro Adapters - Black Nitride

The Dead Air DA012 Detent Ring is the replacement detent plate used across Dead Air's KeyMo and KeyMicro quick-attach suppressor mounting systems. The same part ships standard with every Sandman-series suppressor and is interchangeable between the KeyMo HUB adapter and the KeyMicro adapter, so a single spare covers both platforms.

Built from all-metal construction with a Black Nitride finish, the detent ring is the component that locks the suppressor onto the muzzle device with a positive, repeatable engagement and holds it there under recoil. Because Dead Air offers it as a standalone replacement, it is the logical spare to keep on hand so a worn or misplaced ring doesn't sideline your suppressor setup.

Fitment includes the DA428 KeyMo HUB adapter, the DA451 KeyMicro adapter, and Sandman-series suppressors. The ring installs into the adapter body to restore the precise, repeatable lockup the KeyMo mount is known for.
