Diamondback DB15 Pistol: Compact Power in .300 Blackout

The Diamondback DB15 represents a thoughtful approach to the modern AR pistol—compact enough for close-quarters work, yet powerful enough for serious applications. Chambered in .300 Blackout, this pistol delivers the ballistic authority that discerning shooters demand in a maneuverable platform.

Barrel and Gas System

The 10-inch heavy 4150 Chrome-Moly barrel features a 1:8 twist rate optimized for .300 Blackout performance. A black nitride finish provides superior corrosion resistance and durability. The pistol-length gas system ensures reliable cycling while keeping the overall package compact and controllable.

Construction and Ergonomics

Upper and Lower Receivers: Forged 7075 T-6 aluminum construction throughout provides strength without unnecessary weight. The A3 flattop upper accepts standard optics mounting solutions.

Handguard: The 9-inch M-LOK free-float rail offers genuine accessory mounting flexibility. Whether you're adding lights, lasers, or other tactical equipment, the M-LOK system provides secure, repeatable attachment points.

Controls and Comfort: The Magpul MOE grip ensures positive control and ergonomic consistency. A padded buffer tube enhances comfort during extended shooting sessions and helps manage recoil impulse.
