Diamondback DB15 5.56 NATO 7" Barrel 30+1 OD Green SB Tactical

The Diamondback DB1913K101 DB15 delivers compact firepower with professional-grade components in a pistol configuration. This 5.56 NATO platform combines a heavy-profile barrel with premium furniture for enhanced control and reliability.

What Makes This Different

The 7-inch heavy nitride barrel provides superior heat dissipation compared to standard lightweight profiles, maintaining accuracy during extended firing sessions. The OD Green Cerakote finish on the aluminum receiver offers 2,400+ hour salt spray resistance, significantly outperforming standard anodizing. The 6-inch M-LOK handguard extends nearly to the muzzle, maximizing accessory mounting real estate while keeping the overall length compact.

Key Features

• 7-inch heavy nitride barrel with 1:7 twist rate and threaded muzzle for suppressor compatibility
• Forged 7075-T6 aluminum upper and lower receivers with OD Green Cerakote finish
• 6-inch M-LOK handguard with full-length top rail for optics and accessories
• SB Tactical pistol brace for enhanced stability and control
• Magpul MOE grip with storage compartment and aggressive texturing
• 30-round magazine capacity with standard STANAG compatibility
• Mil-spec trigger group and bolt carrier group

The heavy barrel profile maintains consistent point of impact through temperature changes while the nitride treatment provides corrosion resistance and reduces cleaning time. The M-LOK mounting system accepts accessories at 3, 6, and 9 o'clock positions without adding unnecessary weight. This configuration excels in close-quarters scenarios, vehicle operations, and situations requiring maneuverability without sacrificing terminal performance.
