Diamondback DB15 5.56 NATO Pistol 10" Barrel FDE SBA3 Brace

The Diamondback DB15 delivers reliable semi-automatic performance in a compact pistol platform optimized for close-quarters applications. This 5.56 NATO chambered firearm combines proven direct impingement operation with modern manufacturing standards to create a versatile platform suitable for tactical training and personal protection scenarios.

What Makes This Different

Built on a 7075-T6 aluminum receiver set, this DB15 features a heavy barrel profile that enhances accuracy while managing heat buildup during sustained fire. The Flat Dark Earth Cerakote finish provides superior corrosion resistance compared to standard phosphate coatings, maintaining appearance and function in harsh environments. The 9-inch M-LOK handguard offers significantly more mounting real estate than traditional carbine-length rails while keeping overall length manageable.

Key Features

• 10-inch heavy barrel with 1:7 twist rate for stabilizing heavier projectiles
• SB Tactical SBA3 adjustable pistol brace with five-position adjustment
• 9-inch M-LOK compatible handguard with full-length top rail
• Magpul MOE pistol grip with interchangeable backstraps
• 7075-T6 forged aluminum upper and lower receivers
• 30-round Magpul PMAG included
• Flat Dark Earth Cerakote finish on all major components

Range performance centers on the heavy barrel's ability to maintain consistent point of impact through extended shooting sessions. The 1:7 twist rate stabilizes projectiles from 55-grain to 77-grain effectively, making this platform suitable for both training ammunition and precision loads. The M-LOK handguard accommodates lights, lasers, and vertical grips without requiring additional rail sections, while the SBA3 brace provides stable shooting support in multiple positions.
