The CMMG Dissent MK4 5.7x28mm pistol redefines what a modern personal defense weapon can be. Built on CMMG's patent-pending Compact Action paired with their Radial Delayed Blowback system, the Dissent eliminates the traditional buffer tube entirely—letting you run a genuine PCC platform without the length penalty that usually comes with it. At just 14.7 inches overall and 4.6 pounds, this tungsten gray Cerakote finish gun feels as nimble as it shoots, making it ideal for home defense, vehicle storage, or anywhere you need serious capability in a tight package.

What sets the Dissent apart is its non-reciprocating side charger, swappable from left to right without tools. You can charge the weapon while keeping your eyes and muzzle on target—a genuine tactical advantage that matters when it counts. The 6.5-inch 4140CM barrel (1:9 twist) feeds reliably through the included 32-round magazine, while the CMMG ZEROED Linear Compensator tames what little recoil 5.7x28mm produces. The 5.5-inch M-LOK handguard gives you mounting flexibility, and the rear 1913 Picatinny rail accepts any standard pistol brace or stock so you can configure the gun to your needs and local regulations.

The trigger is a TriggerTech AR-D 2-Stage—engineered specifically for the Dissent platform—with a 4-pound pull weight that's clean and predictable. CMMG builds the upper and lower from 7075 T6 aluminum with a CMMG ZEROED trigger guard and 60/90-degree safety selector. This is a purpose-built gun, not a generic AR pistol conversion. If you're serious about a compact, modern PCC that doesn't compromise on ergonomics or control, the Dissent MK4 in 5.7x28mm is worth your attention.
