Diamondback DB15: A Practical Rifle for Serious Shooters
The Diamondback DB15 represents a thoughtful approach to modern rifle design. Built on proven principles and quality components, it delivers the reliability and accuracy serious shooters demand.
Barrel and Action
The 16-inch barrel is constructed from 4150 ChromeMoly steel with a black nitride finish—a time-tested combination that resists corrosion while maintaining accuracy over thousands of rounds. The mid-length gas system with pinned gas block ensures reliable cycling and reduced wear on components. A shot-peened Mil-Spec 8620 bolt carrier group provides the durability you expect from a rifle built to work.
Receivers and Ergonomics
Forged 7075-T6 aluminum upper and lower receivers provide a solid foundation. The 15-inch M-LOK handguard offers plenty of real estate for mounting optics, lights, and other accessories without unnecessary bulk. An enhanced skeletonized trigger guard keeps your hand comfortable during extended shooting sessions.
Trigger and Controls
The CMC 3.5 lb single-stage drop-in trigger breaks cleanly and consistently—ideal for both precision work and dynamic shooting. Magpul MOE-K2+ grip and ACS-L adjustable stock round out the ergonomic package, allowing you to tailor fit to your body.
Ready to Work
A Diamondback CNC muzzle brake helps manage recoil and muzzle rise. The 30-round magazine capacity and 5.56 NATO chambering make this rifle suitable for sport shooting, training, or home defense. This is a rifle that works—no compromises, no nonsense.
