One thing that has always set the AR15 platform apart from many of its rivals has been modularity. With the 9mm DISSENT available in the Mk4 platform, shooters have a 9mm pistol that can use the CMMG 9 AR Conversion magazines. These magazines feature the same profile as 5.56mm magazines for a familiar manual of arms and true double stack feeding from top to bottom for fast and easy loading. 9mm ammo loadings can vary greatly, from supersonic to subsonic. With a wide range of bullet weights comes new engineering challenges in a new platform. The 9mm Radial Delayed Blowback Compact Action addresses these challenges by utilizing a fixed ejector in the upper receiver. Added benefits are a lighter BCG with less felt recoil while providing consistent performance with a wide range of ammo and maintaining lower compatibility with a wider range of lowers. TriggerTech’s AR-D trigger was developed in collaboration with CMMG to be fully optimized for use with DISSENT firearms and upper receiver groups. With a 4 lb pull weight, the AR-D trigger showcases a light, repeatable break.
