Diamondback DB15 .300 Blackout Pistol 10" Barrel

Diamondback DB15 .300 Blackout Pistol

The Diamondback DB15 represents a serious platform for the shooter who demands reliability and modularity in a compact package. Chambered in .300 Blackout, this pistol delivers the ballistic performance of a rifle cartridge in a form factor suited to close-quarters work and specialized applications.

Barrel and Gas System

The heart of this rifle is a 10-inch 4150 Chrome-Molybdenum Vanadium barrel with a 1:8 right-hand twist, finished in black nitride for corrosion resistance. The pistol-length direct impingement gas system ensures reliable cycling across a wide range of ammunition types, from supersonic to subsonic loads.

Receiver and Handguard

Forged 7075-T6 aluminum upper and lower receivers provide the strength and durability you expect from a modern sporting rifle. The upper features an A3 flattop with Picatinny rail for optic mounting. The 9-inch M-LOK handguard offers ample real estate for accessories while maintaining a trim profile.

Controls and Ergonomics

A Magpul MOE grip provides a comfortable, secure purchase, while the SB Tactical SBA3 brace offers stability and control. The standard mil-spec trigger breaks cleanly and predictably.

Included Accessories

Each DB15 ships with a 30-round Magpul Gen M3 PMAG and an A2 flash hider (5/8 x 24 threads) for muzzle control.
