Diamondback DB15 DB1718B042 | .300 BLK 16in Burnt Bronze

The Diamondback DB15 DB1718B042 is a semi-automatic AR-style rifle chambered in .300 AAC Blackout and built on forged 7075-T6 aluminum receivers with Magpul furniture. It features a 16-inch heavy 4150 CrMoV barrel with a black nitride finish and a 15-inch M-LOK free-float handguard in a Burnt Bronze Cerakote. For a reliable optic under $1,000 that complements this platform, consider a Vortex Strike Eagle 1-6×24 for fast target acquisition and close-to-mid range versatility.

This model suits two common applications: precision short- to medium-range target shooting and hunting with subsonic or supersonic .300 BLK loads. Its configuration emphasizes modularity, including a threaded muzzle and M-LOK mounting options for accessories.
