Diamondback DB15 DB1717K002 | 5.56 NATO | 16″ Barrel

The Diamondback DB15 (DB1717K002) is a semi-automatic modern sporting rifle chambered in 5.56 NATO with a 16-inch medium-contour barrel and a 10-inch free-float quad rail. The design uses forged 7075-T6 aluminum upper and lower receivers, a shot-peened, MPI Mil-Spec 8620 bolt carrier, and a 6-position ATI Mil-Spec buttstock for familiar ergonomics and modularity. This configuration is well suited to range training and practical/competition shooting. A compact low-power variable optic such as a Vortex Viper PST 1-6×24 pairs well for close-to-medium engagements while keeping the rifle light and balanced.
