DEADAIR DA115GOV KEYMICRO GOV FLASH HIDER 1/2-28
The Dead Air Armament KeyMicro GOV flash hider is a precision muzzle device built for shooters who run suppressors and demand reliability under hard use. Threaded 1/2-28 (9mm), it's engineered to pair seamlessly with Dead Air's KeyMo GOV hub adapter system—a mounting solution that combines quick-detach convenience with mechanical secondary retention. This is suppressor-ready gear for duty rifles, precision builds, and anyone serious about consistent accuracy and zero retention.
Constructed from nitride-coated 17-4 stainless steel, the KeyMicro GOV is built to handle extreme heat, high round counts, and aggressive environments without sacrificing performance. The black nitride finish resists corrosion and erosion, extending the service life of your barrel and keeping your rifle running reliably in adverse conditions. Precision machining ensures repeatable lockup, so your suppressor seats the same way every time—critical for accuracy and dependability.
The GOV system's standout feature is its secondary retention mechanism. Unlike traditional QD systems that rely solely on a spring or detent, the KeyMicro GOV incorporates an additional mechanical safeguard when mated with the KeyMo GOV HUB Adapter. Locking requires just 1/2 to 2/3 rotation, giving you true quick-detach speed without sacrificing security. Whether you're running a suppressor for hearing protection, reducing signature, or minimizing recoil, this flash hider delivers the mounting confidence duty and mission-critical shooters expect.
