Diamondback DB15 300 AAC Blackout Pistol 10" FDE SBA3 Brace

The Diamondback DB1916B061 DB15 delivers compact firepower in 300 AAC Blackout, combining a 10-inch heavy barrel with precision engineering for superior ballistic performance. This AR-15 pistol maximizes velocity retention while maintaining maneuverability in tight spaces.

What Makes This Different

The heavy barrel profile provides enhanced accuracy and heat dissipation compared to standard lightweight barrels, maintaining consistent point of impact through extended firing sessions. The 7075-T6 aluminum construction offers 30% greater strength than standard 6061 aluminum, while the Flat Dark Earth Cerakote finish provides superior corrosion resistance rated for 1,200 hours of salt spray testing. The 9-inch M-LOK handguard extends nearly to the muzzle, maximizing accessory mounting real estate.
