Diamondback Firearms DB1731K001 DB15 5.56 NATO 16" 31-Round Carbine

The Diamondback Firearms DB15 5.56 NATO 16" 31-Round Carbine is a modern, duty-ready platform designed for law enforcement, military personnel, and serious civilian operators who demand reliability in high-stress environments. This rifle combines proven AR-15 ergonomics with a compact 16-inch barrel profile, making it effective for close-quarters building clearance, vehicle operations, or rapid-deployment scenarios.

Diamondback engineered this carbine with field-proven design principles: the 5.56 NATO chambering delivers superior ballistic performance and barrier penetration compared to intermediate rounds, while maintaining manageable recoil and ammunition commonality with military and law enforcement inventories. At 8.4 pounds unloaded, the weapon maintains a low-fatigue profile during extended patrols or tactical operations, yet the 16-inch barrel retains adequate muzzle velocity and energy for terminal effectiveness at combat distances.

Law enforcement tactical teams, military support personnel, and trained civilian operators benefit most from this carbine's balance of firepower, mobility, and ergonomic familiarity. The compact 39.9-inch overall length allows operation in vehicles, tight entries, and confined spaces without sacrificing sight radius or handling speed—critical for dynamic scenarios where seconds matter.
