The Diamondback Firearms DB10 is a .308 Win semi-automatic rifle built around forged 7075-T6 aluminum receivers. Its 18-inch fluted 416R stainless steel barrel features a black nitride finish, a 1:10 right-hand twist, and a rifle-length gas system for reliable operation. An M-LOK anti-rotation handguard provides flexible accessory mounting, while the Magpul ACS-L adjustable stock and MOE K2+ grip support a stable, comfortable shooting position. The A3 flattop upper is ready for a user-supplied optic, and the included Diamondback CNC muzzle brake uses 5/8x24 threading. One 20-round Gen M3 PMAG is included.
