Diamondback Firearms Db15 5.56 10" 30-Round Carbine

The Diamondback Firearms DB15 5.56 NATO 10" Barrel AR carbine delivers compact performance without compromising reliability or modularity. Purpose-built for close-quarters environments—from patrol vehicles and home defense to specialized tactical applications—this short-barreled rifle (SBR) bridges the gap between a full-size rifle and a pistol platform. The 10-inch barrel preserves velocity while maintaining the 5.56 NATO's proven lethality, making it ideal for operators who prioritize maneuverability in tight spaces without sacrificing terminal ballistics.

Built on the AR-15 platform, the DB15 features a 9-inch M-LOK compatible handguard system that provides modern accessory mounting options for lights, lasers, and vertical grips. The M-LOK design reduces weight while maintaining structural rigidity and allowing rapid reconfiguration of your tactical setup. At 1.38 lbs (frame weight), this carbine remains controllable in one-handed transitions and prolonged room-clearing operations. The direct impingement system ensures reliability across diverse ammunition batches and environmental conditions—critical for duty use where failure is not an option.

Law enforcement, military personnel, and private security professionals benefit from the DB15's compact footprint without forfeiting the ergonomics and parts compatibility of the AR-15 ecosystem. The 30-round magazine capacity delivers adequate firepower for tactical scenarios while the short overall length (32 inches) facilitates rapid deployment from vehicles and tight entry points. All standard AR-15 components—triggers, bolt carrier groups, and furniture—remain compatible, ensuring sustainment through existing supply chains. Note that SBR configuration may require appropriate federal registration and compliance with local regulations depending on your jurisdiction.
