Diamondback DB15 | 5.56 NATO | 16″ | DB1717K131

The Diamondback DB15 is a 5.56 NATO modern sporting rifle built with forged 7075-T6 receivers and a 16-inch 4150 Chrome-Moly-Vanadium barrel finished in FDE Cerakote. It uses a carbine-length gas system with a 1:8 twist rate and ships without backup sights, making it a straightforward platform for optics and modular accessories. For an all-purpose optic under $1,000 that complements this carbine-style AR, consider a 1-8x variable scout-style scope such as the Vortex Strike Eagle 1-8×24 for close-to-mid range versatility.
