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. The M-LOK handguard allows for sleek accessory mounting to complement your DISSENT while the 1913 picatinny rail end plate allows for the attachment of slings pistol braces or stocks*. Bolt operation is accomplished via the forward non-reciprocating side charger allowing for quick use while staying on target. 9mm ammo loadings can vary greatly from supersonic to subsonic. With a wide range of bullet weights comes new engineering challenges in a 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.
