CMMG Dissent BR4 | 5.56 NATO | 16.10″ | 10+1

The CMMG Dissent BR4 is a CA-compliant semi-automatic carbine chambered in .223 Rem/5.56 NATO with a 16.10″ threaded, black nitride barrel and Magpul SGA black synthetic stock. It ships with two Magpul 10-round PMAGs and features a coyote tan Cerakote on an aluminum receiver with a Picatinny rail. For an optic under $1,000 that complements this platform, consider the Vortex Viper PST Gen II 1-6×24 for versatile close-to-mid-range accuracy and quick target acquisition.

Applications for this rifle include precision range work and varmint or predator hunting where a compact, accurate 5.56 platform is appropriate.
