CMMG 86A7F0B-CT | DISSENT MK4 | 7.62 x 39mm | 14.30″

The CMMG DISSENT MK4 is an AR-pattern rifle chambered in 7.62 x 39mm that pairs AR-style controls and modularity with AK-magazine compatibility. It uses a forward non-reciprocating charging handle and an M-LOK handguard with a top Picatinny rail for accessory mounting. The rifle is fitted with an adjustable gas block and the DISSENT side folding stock with adjustable length of pull and cheek riser for adaptable ergonomics. A practical optic choice under $1,000 for this platform is the Vortex Viper PST Gen II 1-6×24 for rapid target acquisition and mid-range precision.
