CMMG 30A5C0FCT Dissent BR4 | .300 AAC Blackout | 14.5″

The CMMG Dissent BR4 (30A5C0FCT) is a California-compliant AR-style rifle chambered in .300 AAC Blackout, built around a 14.50″ threaded barrel with a pinned and welded brake to meet local length requirements. It ships with two 10-round Magpul PMAGs and a Magpul SGA black synthetic stock for practical handling. The package balances compactness and controllability for short- to mid-range field use and precision-oriented range work. A low-power variable optic such as the Vortex Strike Eagle 1-6x provides a suitable sighting solution under $1000 that complements the platform for short- and medium-range engagements.
