The Diamondback Carbon DB15 in .300 Blackout (MPN DB1796B001) is built for New York-compliant configurations, pairing a 16-inch Diamondback-made 4150 chrome-moly free-float barrel with a black nitride finish and no muzzle threading. Diamondback uses a pistol-length gas system with a shot-peened, magnetic-particle-inspected mil-spec 8620 bolt carrier, forged 7075-T6 aluminum upper and lower receivers, and a 12-inch aluminum M-LOK handguard. The rifle rides on a Thordsen featureless Gen II FRS-15 stock to meet New York’s feature restrictions and feeds from a 10-round Magpul PMAG. Among AR-pattern rifles in the AR rifles category, this DB15 configuration favors shooters in New York and similarly restricted states who need a featureless-compliant .300 Blackout rifle.
