The Dead Air DA302GOV KeyMo GOV Flash Hider is a 5/8-24 .30 caliber KeyMo GOV muzzle device built for hard-use rifles and suppressor-ready setups. This model uses a .30 caliber bore, making it the correct KeyMo GOV flash hider variant for compatible 5/8-24 host barrels 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.
5/8-24 Thread Pitch with .30 Caliber Bore: This DA302GOV version is the 5/8-24 model and Dead Air lists the bore diameter as .30 caliber. It is commonly relevant for compatible .30 caliber rifle barrels using 5/8-24 muzzle threads, but final caliber and suppressor compatibility must be verified before installation or live fire.
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 installation, timing if required, alignment, and all manufacturer instructions before use. Suppressor mounts and muzzle devices should be installed correctly and checked for alignment before live fire.
