Description
JMAC HK MP5 .40/10 360-28FD Facemount Keymount (KeyMicro) - Threaded 1/2x28
The JMAC Customs RRD-360 Muzzle Device offers advanced 360-degree gas venting, reducing recoil and improving control. Its innovative design eliminates the need for timing, allowing easy installation without shims or a crush washer. The 360-28F variant, tailored for KeyMount systems, sleeves over the factory barrel by .98", partially covering the tri-lugs and enabling closer suppressor installation for better balance.
Compatible with KeyMount suppressors and Blast Diversion Shields (BDS) with the correct adapter, the 360-28FD works on barrels threaded 1/2x28 that extend at least 1" beyond the handguard, gas block, or front sight.

*When testing these devices, it was found that high rates of fire such as full auto or “mag dumps” could cause damage to the device due to the excess heat, pressure, and gasses from unburnt powder on shorter barrels.
This device is designed to be tightened against the face of the barrel. You must use face shims (optional) or your barrel MUST be faced to properly time this muzzle device. You can purchase 1/2x28 shims here. If you're not familiar with Facemount devices, click HERE to learn more!
