Purpose-Built Performance The KeyMo(TM) GOV Flash Hider is optimized for durability, consistency, and alignment. Precision machining ensures repeatable suppressor lockup, maintaining accuracy and dependability. Secondary Retention. Elevated Confidence. At the core of the GOV system is enhanced dependability. When used in conjunction with the KeyMo(TM) GOV HUB Adapter, the system incorporates a mechanical secondary retention feature that adds an additional layer of assurance beyond traditional QD systems. With true quick-detach functionality requiring just 1/2 to 2/3 rotation to lock, the result is a mounting solution that remains secure under extreme heat, high round counts, and aggressive use.
