CMMG 60AB40CAB DISSENT BR4 | 6mm ARC | 16.1 in

The CMMG DISSENT BR4 is a modern sporting carbine chambered in 6mm ARC with a 16.1″ barrel and Cerakote Armor Black finish. Its BR4 platform is designed for reduced perceived recoil while delivering the long-range performance associated with the 6mm ARC cartridge. Ambidextrous controls and a reversible side charger make this a practical option for a range of shooters. For an optic that pairs well without exceeding $1,000, consider a Vortex Viper PST 1-6×24 as a versatile, durable choice for both close and extended-range work.

Recommended applications include precision-oriented target shooting at extended ranges and medium-game hunting where flat trajectory and moderate weight are priorities.
