Diamondback Firearms DB1731K071 DB15 5.56 NATO 16" 31-Round Carbine

The Diamondback Firearms DB15 5.56 NATO 16" 31-round carbine is a modern direct impingement rifle built for law enforcement, military training, and civilian defensive use. This 8.4-pound platform delivers the modularity and reliability demanded by professional operators and serious shooters who require a lightweight, ergonomic carbine for duty or sport. The 16-inch barrel balances velocity retention with compact handling, making this rifle equally effective in vehicle operations, close-quarters patrol, or three-gun competition.

The DB15 carbine employs proven direct impingement gas operation and a standard AR-15 compatible receiver platform, ensuring straightforward maintenance and parts interchangeability with existing inventory. The 16-inch 5.56 NATO barrel is optimized for 62-grain and heavier duty rounds, delivering consistent muzzle velocity and inherent accuracy across common military and commercial loads. A 31-round magazine capacity provides extended engagement capability while remaining practical for tactical reloads; the lightweight overall construction minimizes shooter fatigue during extended operations without sacrificing durability or sight radius for accurate fire.

This carbine serves law enforcement marksmen, military personnel conducting qualification or training, and civilian defenders prioritizing a professional-grade platform. The direct impingement design and standard AR-15 interface support rapid accessory configuration—sights, optics, lights, and suppressors mount seamlessly to Picatinny rails and standard threaded muzzles. Operators familiar with military-pattern rifles will find the controls intuitive and maintenance routine; the 31-round magazine maximizes tactical readiness while the compact 16-inch profile excels in vehicle, building, and low-light scenarios where maneuverability and firepower intersect.
