Diamondback DB15 AR Pistol 5.56/.300BLK 7" Barrel FDE Magpul Grip

The Diamondback DB15 AR pistol delivers reliable performance in a compact platform optimized for close-quarters applications and tactical mobility. This dual-caliber capable firearm accepts both 5.56 NATO and .300 Blackout ammunition through simple upper receiver changes. The black nitride finish provides enhanced corrosion resistance and reduced friction for consistent cycling.

What Makes This Different

The DB15 features a proprietary bolt carrier group with enhanced steel construction and improved gas key staking compared to standard mil-spec components. The 7-inch barrel with 1:7 twist rate stabilizes heavier projectiles effectively while maintaining a 26-inch overall length for maneuverability. Black nitride treatment penetrates the steel surface rather than coating it, providing superior wear resistance compared to standard phosphate finishes.

Key Features

• Dual caliber capability - 5.56 NATO and .300 Blackout compatible
• 7-inch chrome-lined barrel with 1:7 twist rate and carbine-length gas system
• Black nitride finish on barrel and bolt carrier group for corrosion resistance
• Flat Dark Earth Cerakote receiver finish with Type III hard coat anodizing
• Magpul MOE pistol grip with storage compartment and enhanced texture
• Standard AR-15 trigger group and safety selector compatibility

The carbine-length gas system provides reliable cycling with both supersonic and subsonic ammunition loads. The platform performs consistently in temperature ranges from -40°F to 140°F according to military testing standards. Accuracy potential reaches 2-3 MOA with quality ammunition, making it suitable for precision applications within its effective range. The compact dimensions excel in vehicle operations, confined spaces, and situations requiring rapid target engagement.
