About this product

The Diamondback DB-15 Carbon Series pistol is a compact AR-style semi-automatic chambered in .300 AAC Blackout designed for short-range utility and modular customization.

Forged 7075-T6 upper and lower receivers, a 9-inch PC M-LOK handguard and a Magpul MOE pistol grip provide a familiar AR interface. The SB Tactical SBA3 arm brace and a Magpul Gen M3 30-round PMAG are included to make the platform ready for immediate configuration.
