Dead Air KeyMicro GOV Flash Hider 9mm 1/2-28

This is a flash hider that pulls double duty as a suppressor mount. On its own it breaks up muzzle flash on a 9mm host threaded 1/2-28. Paired with the KeyMo GOV HUB adapter it becomes the front half of the KeyMicro GOV mounting system, and that system adds a mechanical secondary retention feature on top of the usual quick detach interface.

Machining is held tight enough that the can returns to the same lockup every time you take it off and put it back on, which is the part that actually protects your zero. Stainless steel construction handles the heat that a mount sees.
