CMMG 64A190CCT Dissent BR4 | 6.5 Grendel | 16.10 in

The CMMG Dissent BR4 is an AR-pattern rifle chambered in 6.5mm Grendel designed for medium to long-range shooting with an emphasis on stable, efficient ballistics. This CA-compliant configuration pairs a 16.10-inch nitride threaded barrel to a Coyote Tan Cerakote aluminum receiver and a Magpul SGA black synthetic stock. It ships with two CMMG 10-round magazines and a CMMG Zeroed muzzle brake. A practical optic choice under $1,000 that complements the platform is the Vortex Viper PST Gen II 1-6×24 for flexible close-to-mid-range precision.
