The Dead Air Armament KeyMo GOV Flash Hider is a precision 1/2-28 threaded muzzle device engineered for shooters who demand reliability under hard use. Built from nitride-coated 17-4 stainless steel, this 6mm flash hider is designed to work seamlessly with Dead Air's KeyMo GOV suppressor mounting system, delivering both flash reduction and the foundation for a quick-detach suppressor setup that stays locked in place during extended shooting, elevated temperatures, and tactical use.
The GOV series reflects Dead Air's commitment to professional-grade equipment that prioritizes dependability over compromise. When paired with a KeyMo GOV HUB Adapter, the system incorporates secondary mechanical retention—a genuine backup lock beyond typical quick-detach interfaces. This means your suppressor stays mounted with confidence through aggressive shooting and adverse conditions. The flash hider itself requires only a half to two-thirds rotation for attachment, keeping your setup fast and repeatable in the field.
Nitride coating provides excellent corrosion and erosion resistance, making this device suitable for long-term duty use in challenging environments. At 4.08 ounces and 2.70 inches long, it adds minimal weight and length to your rifle while delivering the durability you'd expect from a platform designed for law enforcement and military standards.

Yes. The 1/2-28 thread pitch and 6mm bore are standard for .223 Remington and 5.56 NATO rifles. Verify your barrel is threaded 1/2-28 before purchase.
No, this is the flash hider only. It serves as the mounting interface for a Dead Air KeyMo GOV-compatible suppressor (sold separately) and works with a KeyMo GOV HUB Adapter to provide secondary retention.
The KeyMo GOV system adds a mechanical secondary retention feature when used with the KeyMo GOV HUB Adapter. This backup lock keeps your suppressor secure under sustained heat and high round counts, beyond what a simple QD interface alone provides. Attachment still requires only a quick 1/2 to 2/3 rotation.
Nitride coating provides strong resistance to corrosion, erosion, and wear. It's chosen for this flash hider specifically to extend service life in duty and high-use environments, including adverse conditions.
