The Dead Air DA301GOV KeyMo GOV Flash Hider is a 1/2x28 KeyMo GOV muzzle device built for hard-use rifles and suppressor-ready setups. This model uses a 6mm bore, making it suitable for compatible 1/2x28 host barrels and appropriate calibers within Dead Air’s stated bore and suppressor compatibility limits.
The KeyMo GOV Flash Hider is part of Dead Air’s GOV series and is designed for durability, consistency, and repeatable suppressor alignment. Dead Air describes the GOV system as providing enhanced dependability when used with the KeyMo GOV HUB Adapter, including a mechanical secondary retention feature that adds another layer of assurance beyond traditional quick-detach systems.
KeyMo GOV Mounting System: When used with the correct Dead Air KeyMo GOV HUB Adapter and compatible suppressor setup, the GOV system provides true quick-detach functionality with approximately 1/2 to 2/3 rotation to lock. This is intended to help maintain secure suppressor attachment under heat, high round counts, and aggressive use.
1/2x28 Thread Pitch with 6mm Bore: This DA301GOV version is the 1/2x28 model and Dead Air lists the bore diameter as 6mm. Always confirm barrel thread pitch, shoulder geometry, caliber, bore clearance, suppressor compatibility, and alignment before installation or use.
17-4 Stainless Steel Construction: Dead Air lists the KeyMo GOV Flash Hider as constructed from 17-4 stainless steel with a black nitride finish. This combination is intended to resist corrosion, erosion, and wear during demanding field, duty, and suppressed-fire use.
Flash Hider Function: The KeyMo GOV Flash Hider is designed to reduce visible muzzle flash while also serving as a suppressor mounting interface for compatible Dead Air KeyMo GOV setups. It is not a direct-thread suppressor adapter by itself; the full mounting system and suppressor compatibility must be confirmed separately.
Important Fitment Note: Confirm barrel thread pitch, caliber, bore clearance, muzzle shoulder, suppressor model, KeyMo GOV HUB Adapter compatibility, proper timing/installation, alignment, and all manufacturer instructions before use. Suppressor mounts and muzzle devices should be installed correctly and checked for alignment before live fire.
