Diamondback DB15 | 5.56 NATO | 16″ Barrel | 10+1 | DB1790K001

The Diamondback DB15 is a California-compliant AR-style semi-automatic rifle built with forged 7075-T6 receivers, a 16″ Diamondback 4150 chrome-moly barrel with a black nitride finish, and a 12″ M-LOK handguard. It ships with a Magpul MOE carbine stock and a single Gen M3 10-round magazine; sights are optic ready. For a practical optic under $1,000 that pairs well for typical AR shooting applications, consider a 1-6×24 low-power variable optic such as the Vortex Strike Eagle for close-to-medium range versatility.
