CMMG DISSENT MK4 300 BLK 6.5″ 30+1 | 30A0E33CT

The CMMG DISSENT MK4 is a compact, buffer-less AR pistol built around CMMG’s Compact Action for a highly portable, modular platform. Chambered in .300 AAC Blackout with a 6.5″ free-floated barrel and a 5.5″ M-LOK handguard, it integrates ambidextrous controls and a side charger that can be configured for left- or right-handed operation. For a rugged red-dot that complements the DISSENT without exceeding $1,000, consider a Vortex Venom 3 MOA for fast target acquisition and durable performance. Recommended applications: close-range precision practice and short-range hunting where a compact, powerful AR platform is preferred.
