Diamondback Firearms DB105AC221 DB10 308 16" 21-Round FDE Carbine

The Diamondback Firearms DB105AC221 DB10 308 16" 21-Round FDE Carbine is purpose-built for law enforcement, military, and professional shooters who demand a compact, battle-proven platform in the hard-hitting .308 Winchester cartridge. Derived from the AR-10 architecture, this rifle delivers the ballistic authority of a full-power rifle in a manageable package that excels in vehicle operations, close-quarters tactical scenarios, and precision engagements beyond 300 meters. The flat dark earth finish blends durability with a low-visibility aesthetic suited to multi-environment deployments.

At 9.86 pounds with a 16-inch barrel, the DB10 maintains excellent handling characteristics while preserving muzzle velocity necessary for .308 performance in intermediate-range work. The 21-round magazine capacity provides tactical flexibility and reduces reload frequency in dynamic scenarios—a genuine operational advantage over standard 20-round configurations. The AR-pattern ergonomics and controls allow seamless integration with modern tactical accessories, mounting systems, and optics platforms familiar to trained operators. The 38-inch overall length keeps the platform compact for transport and deployment in confined spaces without sacrificing sight radius or accuracy potential.

This carbine suits professional and civilian marksmen seeking a reliable, modular .308 platform with proven reliability and accuracy. Law enforcement tactical teams, military personnel, and serious sport shooters benefit from its lightweight construction, manageable recoil impulse, and compatibility with standard AR-10 accessories and upgrades. The FDE finish resists corrosion in austere environments while maintaining a professional appearance in duty and training applications. Mounting for optics, lights, and accessories follows established mil-spec patterns, ensuring long-term support and parts availability.
