Diamondback DB1984K101 Obsidian 5.56 NATO 11.5" Pistol MOE K2 SBA5

The Diamondback DB15 Obsidian delivers compact firepower with full-size reliability in a pistol-length platform. This 5.56 NATO chambered firearm bridges the gap between portability and performance with its 11.5-inch barrel and stabilizing brace configuration.

What Makes This Different

The DB15 Obsidian features a black nitride-treated barrel that provides superior corrosion resistance compared to standard phosphate coatings. The 11-inch M-LOK handguard offers extensive customization options while maintaining a lightweight profile. Factory-installed SBA5 pistol brace provides improved control and accuracy over traditional buffer tube configurations.

Key Features

• 11.5-inch black nitride barrel with 1:8 twist rate for optimal bullet stabilization
• 11-inch M-LOK compatible handguard with full-length top rail
• SB Tactical SBA5 adjustable pistol brace for enhanced stability
• Magpul MOE K2 pistol grip with improved ergonomics and storage compartment
• 30-round Magpul PMAG included for immediate deployment
• Standard AR-15 trigger group and bolt carrier group compatibility
• Mil-spec charging handle and safety selector

This configuration excels in close-quarters applications where maneuverability matters most. The 11.5-inch barrel maintains sufficient velocity for effective terminal performance while reducing overall length by 4.5 inches compared to carbine variants. Black nitride treatment extends barrel life and simplifies maintenance in adverse conditions.
