CMMG DISSENT MK4 | 5.7x28mm | 6.5″ | 32rd

The CMMG DISSENT MK4 in 5.7x28mm is a compact AR-style pistol built around CMMG’s Compact Action and radial delayed blowback system. It ships with a 6.5-inch barrel, a 32-round magazine, and a proprietary 5.5″ M-LOK handguard. For an optic, an all-purpose choice such as the Vortex Strike Eagle 1-6×24 pairs well with this platform for fast target acquisition and flexible magnification and sits comfortably under a $1,000 budget. Typical applications include range training and PCC-style competition where compact handling and high capacity matter.
