CMMG DISSENT MK4 | 6.5 Grendel | 16.1 in

The CMMG DISSENT MK4 is a factory-built rifle chambered in 6.5 Grendel with a 16.1-inch barrel and a side-folding DISSENT stock. It combines a compact direct-impingement action with a 416 stainless barrel and CMMG’s ZEROED components for a durable, modular package. This configuration is well suited to medium-range target shooting and hunting applications. For optics, a practical pairing under $1,000 is the Vortex Viper PST 1-6×24 for close-to-medium range versatility.
