The Diamondback Firearms DB15 is a versatile 5.56 NATO semi-automatic rifle built around lightweight 7075-T6 aluminum receivers. Its 16-inch medium-profile 4150 Chrome Moly steel barrel uses a carbine-length direct-impingement gas system and a pinned gas block for dependable operation. A 15-inch M-LOK anti-rotation handguard provides flexible accessory mounting, while the Magpul MOE grip and six-position carbine stock support a comfortable, adaptable shooting position. The rifle includes a threaded muzzle with an A2 flash hider and a 1:8 twist rate suited to a broad range of bullet weights.
