The CMMG Dissent BR4 in .300 AAC Blackout (brand part no. 30A5C0FCT) brings one of the most versatile calibers on the market to a compact, California-compliant configuration finished in Coyote Tan. CMMG pairs a 14.5-inch black nitride threaded barrel with a 1:7-inch twist, and a pinned-and-welded ZEROED SVD muzzle brake brings the overall barrel length to 16.1 inches, keeping the rifle NFA-tax-stamp-free. The rifle feeds from two included 10-round Magpul PMags, and a Coyote Tan Cerakote-finished aluminum receiver pairs with a Magpul SGA black synthetic stock and a Picatinny top rail. Among modern sporting rifles in the AR rifles category, the Dissent BR4 favors California shooters who want a compact .300 Blackout carbine in a distinctive finish.
