The Diamondback Firearms DB15 is a modern sporting rifle chambered in 5.56 NATO and configured for versatile range, training, and utility use. Its 16-inch medium-profile 4150 chrome moly barrel uses a mid-length gas system and a 1:8 twist rate for balanced handling and broad bullet compatibility. A 15-inch M-LOK handguard provides flexible space for accessory mounting, while the Magpul MOE grip and adjustable carbine stock improve control and fit. The rifle uses 7075-T6 aluminum receivers and a shot-peened Mil-Spec 8620 bolt carrier. Its threaded barrel and optic-ready receiver support further configuration, and one 30-round Gen 3 PMAG MCT is included.
