CMMG DISSENT MK4 9mm pistol with a 6.5-inch threaded barrel, Cerakote finish, M-LOK handguard and left-side non-reciprocating charging handle. Optic-ready platform suitable for range work and PCC competition.
The CMMG DISSENT MK4 is a purpose-built 9mm AR-pattern pistol that emphasizes modularity and reliable feeding with CMMG 9 AR conversion magazines. It ships with a 6.50-inch threaded barrel and a Cerakote finish, and features a 5.50-inch M-LOK handguard plus a 1913 Picatinny rail end cap for accessory mounting. The left-side non-reciprocating charging handle and a TriggerTech AR-D drop-in trigger are part of the MK4 configuration.
For a matching optic under $1,000, consider a low-power variable optic such as the Vortex Strike Eagle 1-6×24 (or similar 1-6/1-8 LPVO) mounted to the Picatinny rail; it provides a useful balance between close-quarters speed and precision out to practical pistol-caliber ranges. Typical applications for this platform include range practice and pistol-caliber carbine (PCC) competition.
