The Diamondback DB1916B001 DB15 Pistol is purpose-built for shooters who want the ballistic performance of the .300 AAC Blackout cartridge in a compact, rugged, and highly maneuverable platform. Whether you’re planning to run it suppressed or seeking a lightweight alternative to a full-length rifle, this AR-style pistol delivers in both function and form.
Built on forged 7075-T6 aluminum receivers, the DB15 maintains strength and structural integrity while minimizing weight. The Type III hard coat anodized finish protects against wear, corrosion, and the elements—ensuring the pistol can withstand demanding use in various environments.
At the heart of this setup is a 10-inch heavy-profile barrel chambered in .300 AAC Blackout, optimized for stabilization of both supersonic and subsonic rounds. The black nitride finish enhances barrel life and performance, offering reduced fouling, smoother cycling, and easier cleaning.
The barrel is threaded 5/8×24, ready to accept a variety of muzzle devices, including flash hiders, compensators, or suppressors. This makes the DB15 particularly well-suited for those planning to build a suppressed setup or maximize recoil management.
The free-float M-LOK handguard offers plenty of mounting options for lights, lasers, vertical grips, or bipods without adding bulk. Because it doesn’t contact the barrel, the free-float design also contributes to improved accuracy and heat dissipation.
Internally, the DB15 uses a carbine-length gas system and a standard AR-15 bolt carrier group. This setup provides reliable cycling with most factory ammunition and compatibility with widely available AR-15 components and upgrades.
The SB Tactical SBA3 pistol brace enhances stability and comfort during firing while maintaining legal compliance for a pistol configuration. The brace is adjustable for length of pull and incorporates a rear QD sling attachment point for flexibility in carry options.
