Why the Dissent Matters
The elimination of the buffer tube and spring assembly fundamentally changes what's possible in a compact platform. The result is the shortest, most stowable personal defense weapon CMMG has produced. The 5.7x28mm cartridge offers low recoil, manageable noise levels, and effective terminal performance in a package that fits where traditional rifles cannot.
The free-floated barrel ensures consistent accuracy, while the M-LOK handguard provides mounting flexibility for lights, lasers, and other tactical accessories. Whether you're seeking a truck gun, home defense option, or portable training platform, the Dissent MK4 delivers genuine innovation in a proven caliber.
