CMMG Dissent BR4 | 28AC60CCT | .22 ARC | 16.10 in

The CMMG Dissent BR4 in .22 ARC is a CA-compliant AR-format rifle built on the BR4 platform and finished in coyote tan Cerakote on an aluminum receiver. It pairs a 16.10-inch medium-taper threaded barrel and a CMMG Zeroed muzzle brake with a Magpul SGA stock and a zeroed single-stage trigger for consistent operation. The rifle ships with two 10-round CMMG magazines and reversible/ambidextrous controls suited to a range of shooters. For an optic under $1,000 that complements this platform, consider the Vortex Strike Eagle 1-6×24 for low- to mid-power versatility and clear glass for practical precision.

Common applications include precision target shooting and varmint/medium-varmint hunting where the .22 ARC’s higher-velocity performance is desired without stepping up to larger calibers.
