The Diamondback Firearms DB15 is a practical AR-15-style semi-automatic rifle chambered in 5.56 NATO and compatible with .223 Remington. Its 16-inch 4150 CMV steel barrel uses a 1:8 twist and a carbine-length gas system for a versatile general-purpose setup. A 15-inch M-LOK free-float handguard provides flexible accessory mounting while helping preserve barrel consistency, and the Picatinny top rail is ready for an optic. The rifle features lightweight 7075-T6 aluminum receivers, M4 feed ramps, a Mil-Spec trigger, an A2 flash hider, and a collapsible stock. The Burnt Bronze finish gives this configuration its distinctive appearance.
