Diamondback Firearms DB1915K071 DB15 5.56 NATO 10" 31-Round AR Rifle

The Diamondback Firearms DB1915K071 DB15 5.56 NATO 10" 31-Round AR Rifle is purpose-built for shooters who demand a compact, maneuverable platform without sacrificing firepower or reliability. This short-barreled rifle (SBR) excels in close-quarters tactical environments, home defense scenarios, and training applications where mobility and rapid target engagement are mission-critical. The 10-inch barrel paired with a 31-round magazine capacity delivers the punch of an intermediate rifle in a form factor that transitions smoothly through tight spaces—a configuration refined through decades of military and law enforcement operational feedback.

Built on the proven AR-15 platform, the DB15 combines Diamondback's reputation for precision manufacturing with direct impingement operating system efficiency and inherent accuracy. The 10-inch barrel optimizes velocity-to-maneuverability trade-offs, maintaining effective 5.56 NATO ballistics out to 300 meters while keeping overall length at 32 inches—ideal for vehicle storage, breaching operations, or rapid deployment from concealment. The 31-round magazine capacity ensures sustained suppressive fire and reduces reload frequency during extended engagements, while the rifle's 6.8-pound weight facilitates all-day carry without fatigue. Precision-machined receiver components and a chrome-lined barrel deliver consistent shot grouping and extended service life even under high round count and adverse conditions.

This configuration benefits law enforcement, military personnel, competitive shooters, and civilian defenders prioritizing situational responsiveness and terminal effectiveness. The compact profile integrates seamlessly with modern tactical accessories—rail systems accept lights, lasers, and optics without modification. SBR registration requirements apply in most jurisdictions; users must comply with federal NFA (National Firearms Act) regulations before possession. The Diamondback DB15 represents a mature design refined through real-world operational demands, delivering the reliability and accuracy that professionals trust when performance cannot be compromised.
