CMMG Dissent BR4 | .22 ARC | 16.1 in | 10rd

The CMMG Dissent BR4 is a semi-automatic modern sporting rifle chambered in .22 ARC, built on the BR4 platform with a Magpul SGA Remington 870-pattern stock and a 16.1 inch barrel. It ships with two CMMG 10-round magazines and a factory ZEROED drop-in single-stage trigger. The rifle features ambidextrous/reversible controls, an M-LOK handguard and a car-length gas system, finished in black Cerakote. For a capable optic under $1,000 that pairs well with this platform, consider the Vortex Strike Eagle 1-8×24 for its durability and versatile magnification range.
