The Diamondback Firearms DB1913K101 DB15 5.56 7" 31-Round Carbine is a compact, modern sporting rifle engineered for tactical deployment, home defense, and professional law enforcement use. This short-barreled platform delivers the ballistic efficiency of 5.56 NATO in a highly maneuverable 7-inch package, making it ideal for confined spaces, vehicle operations, and close-quarters scenarios where full-length carbines become a liability.

At 6.95 lbs, this carbine achieves a favorable balance between durability and handling speed—critical factors in high-stress tactical operations where weapon fatigue directly impacts accuracy and target transition speed during extended engagements.

Law enforcement operators, military personnel, and serious civilian preparedness enthusiasts will find the DB15 5.56 7" carbine exceptionally valuable in CQB training, vehicle-based operations, and deployment scenarios where barrel length restrictions exist. The Mil-Spec AR-15 design ensures seamless integration with modern optics mounting systems, tactical accessories, and aftermarket components—allowing rapid customization for specialized mission profiles. Given the DB1913K101's compact dimensions (31.5 inches overall length) and proven caliber pairing, this platform excels in precision training, low-light operations, and field applications where maneuverability and stopping power must coexist.
