The Diamondback DB10 Black Gold .308 Win is a semi-automatic AR-10 rifle built around an 18-inch 416-R stainless steel barrel (brand part no. DB1032C001). The line sits in the middle of the Diamondback Firearms DB10 range, adding a Black Gold lower with an enhanced trigger guard, a V-Rail handguard with anti-slip texture pads and upgraded Magpul furniture. Rifle-length direct impingement gas keeps recoil manageable in a full-power .308 platform. The flat-top upper has no iron sights, so it is ready for the optic of your choice on a hunting, range or general-purpose build.

Key Specifications

• Caliber is .308 Winchester, the full-power cartridge this DB10 is chambered for.
• The barrel is 18 inches of 416-R stainless steel in a medium profile, which resists corrosion and holds accuracy through long strings.
• Rate of twist is 1:10 right-hand, a rifling pitch that suits the common .308 bullet weights.
• The gas system is rifle-length direct impingement, which spreads out the recoil impulse on this full-size platform.
• The finish is black hardcoat anodize, a durable coating on the forged aluminum receivers.

• The included magazine is a Magpul Gen M3 PMAG, 20 rounds, a polymer magazine built for the DB10 pattern.

• Overall weight is 8.7 pounds, and length runs 36 inches collapsed to 39.25 inches extended for a steady, controllable rifle.
