Diamondback Firearms DB1718K001 DB15 5.56 16" 31-Round Carbine

The Diamondback Firearms DB1718K001 DB15 5.56 16" 31-Round Carbine is a modern direct impingement rifle engineered for law enforcement, military units, and serious civilian shooters who demand reliability in a compact, duty-ready platform. This 5.56 NATO carbine delivers the performance of a full-size rifle in a 16-inch profile, making it ideal for vehicle storage, CQB training, home defense, and patrol operations where maneuverability matters. Built on time-proven AR-15 architecture, the DB15 carbine integrates seamlessly into existing tactical ecosystems and training protocols.

The 16-inch barrel balances muzzle velocity with handling—typical 5.56 loads achieve 2,800+ fps from this length, sufficient for intermediate ranges and barrier penetration. The direct impingement system cycles reliably under rapid fire and suppressive conditions, while the 31-round magazine capacity provides serious engagement duration without frequent reloads. At 8.4 pounds unloaded, the carbine remains light enough for extended operations yet substantial enough for stable shooting positions. The compact 39.5-inch overall length allows one-handed weapon manipulation in confined spaces and reduces snag points during tactical movement or vehicle transition.

Law enforcement entry teams, military personnel, and armed civilians seeking a do-it-all carbine will find the DB1718K001 immediately compatible with standard AR-15 optics mounts, rail systems, and aftermarket components—no gunsmith work required. The platform accepts industry-standard magazines, ammunition, and parts, ensuring supply chain reliability during training cycles or emergency deployment. Whether mounted with a red dot, magnified optic, or iron sights, this rifle transitions rapidly between targets and engagements, making it suitable for force protection, precision rifle courses, and high-round-count training evolution. Proper maintenance and regular function testing confirm readiness for duty or sport use.
