CMMG Mk4 Dissent Rifle | 5.56mm | 14.5″ Pinned & Welded

The CMMG Mk4 Dissent is a compact 5.56mm AR-pattern rifle built for adjustable gas tuning and folding-stock convenience. It ships with a 14.5″ barrel that is pinned and welded to achieve a 16.1″ overall length, a 13.5″ M-LOK handguard and two 30-round magazines. This configuration is useful for range work and precision training where a shorter overall length and adjustable gas system are valued. Consider a Vortex Viper PST Gen II 1-6×24 as an optic option under $1000 to pair with this platform for general-purpose shooting and low- to mid-range precision.
