Diamondback DB15 300 Blackout Pistol, 10" Barrel, FDE

Diamondback DB15 300 Blackout Pistol

The Diamondback DB15 represents a thoughtful approach to the modern pistol-caliber rifle platform. Chambered in 300 Blackout, this compact carbine delivers the ballistic advantages of a larger cartridge in a package suitable for close-quarters work and suppressed fire.

Barrel and Action

Barrel: The 10-inch heavy barrel is manufactured from 4150 Chrome-Moly steel with black nitride finish, providing durability and corrosion resistance. The 1:8" twist rate is optimized for 300 Blackout performance across the full range of subsonic and supersonic loads.

Gas System: A pistol-length gas system ensures reliable cycling while maintaining the compact overall profile.

Bolt Carrier Group: The carrier is shot-peened and magnetic particle inspected, meeting military specifications for the 8620 steel used in its construction.

Receiver and Furniture

Upper and Lower Receivers: Both are forged from 7075 T-6 aluminum, providing strength while keeping overall weight to 5.1 pounds. The upper features an A3 flattop for optic mounting.

Handguard: The 9-inch M-LOK rail offers modern accessory mounting without unnecessary bulk.

Controls: Standard trigger, Magpul MOE grip, and padded buffer tube provide comfortable, reliable operation.
