Diamondback Firearms DB1718K071 DB15 Carbon 5.56 NATO 16" 31-Round Rifle

The Diamondback Firearms DB1718K071 DB15 Carbon 5.56 NATO 16" rifle is purpose-built for tactical operators, law enforcement, and serious shooters who demand reliability without compromise. This mid-length platform delivers the ergonomic refinement and modularity expected from modern combat rifles while maintaining sub-9-pound weight for extended operations. Whether deployed for duty, competition, or home defense, the DB15 Carbon bridges the gap between budget-conscious acquisition and duty-grade performance.

Built on a direct-impingement system, the DB15 Carbon pairs a 16-inch barrel with a free-floating configuration to maximize accuracy potential across combat distances. The carbon fiber handguard reduces weight while maintaining rigidity needed for consistent sight picture and accessory mounting; this design choice is critical for shooters running optics, lights, or lasers that depend on zero stability. The 31-round magazine capacity aligns with standard NATO 5.56 dimensions, ensuring compatibility with existing logistics and inventory across teams or departments. At 8.35 pounds unloaded, the rifle minimizes fatigue during sustained operations while the 39.5-inch overall length keeps the platform maneuverable in vehicles, tight quarters, and dynamic entries.

Law enforcement and military end-users benefit from the DB15 Carbon's straightforward maintenance, standard AR15 parts commonality, and rail-ready platform that accepts any Picatinny-compatible accessories. The 5.56 NATO chamber fires both .223 Remington and 5.56 ammunition, giving shooters flexibility in load selection for training or duty use. Home defenders and competitive shooters appreciate the 16-inch barrel's balance of velocity retention and handling; this length provides superior ballistics to SBR platforms while remaining legally accessible in all 50 states without NFA registration. Verify local compliance and ensure proper FFL transfer before purchase.
