The Diamondback DB15 Carbon Series is a compact AR-style pistol chambered in .300 AAC Blackout designed for close-quarters use, duty-style configurations, and range work. It pairs a 10″ barrel and a pistol stabilizing brace to deliver familiar AR ergonomics in a shorter package. The platform is built for modularity, letting users fit optics and accessories on the flattop upper and M-LOK handguard.

Key Specifications

  • The firearm is chambered in .300 AAC Blackout for compatibility with commonly available supersonic and subsonic ammunition types.
  • The barrel measures 10 inches, providing a compact overall footprint for close-range and bench use.
  • The twist rate is 1:8 right-hand, matched to common .300 AAC Blackout bullet weights.
  • The action uses a pistol-length direct impingement gas system consistent with AR-15 style operation.
  • The upper and lower receivers are forged 7075-T6 aluminum for strength and reduced weight.
  • The handguard is a 9-inch PC M-LOK rail to accept lights, grips, and other accessories.
  • The pistol ships with an SB Tactical SBA3 pistol stabilizing brace to improve controllability in a pistol configuration.
  • A 30-round Magpul PMAG (.300 AAC Blackout) is included with the pistol.
  • The muzzle device is an A2 flash hider, factory-installed.
  • The unloaded weight is approximately 5.7 lb, and overall length is 26 in (collapsed) / 28.5 in (extended).

State magazine-capacity limits may affect lawful ownership and use of the included 30-round magazine; limits to 10 rounds apply in: Hawaii, California, Connecticut, District of Columbia, Illinois, Maryland, Massachusetts, New Jersey, New York, Rhode Island, Vermont, Washington, and Colorado. Confirm local laws before purchase and possession.

The DB15 Carbon Series emphasizes modularity and familiar AR ergonomics in a compact package, making it suitable for range work and applications where a shorter-profile AR pistol is desired. Construction centers on forged 7075-T6 receivers and an M-LOK handguard for accessory flexibility. Users seeking a compact AR-platform pistol that accepts common AR accessories will find the DB15 a straightforward, hard-use oriented option.
