DEADAIR DA301GOV KEYMO GOV FLASH HIDER 1/2-28 6MM

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.

Frequently Asked Questions

Will this flash hider work with my .223 or 5.56 rifle?

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.

Does this come with a suppressor?

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.

What makes the GOV system different from a standard quick-detach muzzle device?

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.

How durable is the nitride coating?

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.
