Challenge convention, the CMMG® DISSENT™ in 5.7x28mm is here to change the way you look at Personal Defense Weapons. One of the biggest challenges AR-15 platform PDWs face is the buffer tube, a necessity that always adds to the overall footprint until now. The DISSENT eliminates the need entirely by employing our patent-pending Compact Action that also works hand in hand with our renowned Radial Delayed Blowback™ operating system.

In addition to containing the entire action and recoil system in a more compact package, every DISSENT features a forward non-reciprocating side charger, interchangeable from left to right, allowing shooters to charge the weapon while staying focused on target.
