Diamondback DB15CCML300B | DB15 .300 Blackout | 16″

The Diamondback DB15CCML300B is a U.S.-made AR-style rifle chambered in .300 Blackout with a 16″ free-float barrel and a 12″ M-LOK handguard. It uses a carbine-length gas system and a forged 7075 T6 aluminum upper and lower receiver set, finished in black hardcoat anodize. For an optic under $1,000 that complements this platform, consider a Vortex Strike Eagle 1-6×24 for fast acquisition and useful magnification for close-to-medium range work.

Real-world uses for this rifle include short-range hunting and practical close-to-medium-range target shooting. The rifle is configured as a modern sporting carbine suitable for accuracy with supersonic and subsonic .300 Blackout loads when paired with the correct suppressor or muzzle device.
