DIA DB175AK002 DB15 5.56 NATO 16" Carbine

The Diamondback DB15 556 16" 30R in Black (model DB175AK002) is a modern carbine-length 5.56 NATO rifle engineered for patrol, training, and tactical deployment. Built entirely in the USA, this platform combines precision manufacturing with field-proven ergonomics to deliver a carbine that operators and law enforcement professionals rely on for consistent, accurate performance across demanding environments.

Core specifications center on proven reliability and controllability. The rifle features a 16-inch 4150 CrMov barrel with carbine-length gas system tuning for optimal cycling velocity and lower wear rates. The bolt carrier group is shot-peened and Magnetic Particle Inspected (MPI) mil-spec 8620 steel—the standard for military and law enforcement platforms. The upper receiver is forged 7075 T-6 aluminum with A3 flattop profile and T-marked designation, while the lower receiver employs carbon fiber construction for weight savings. The 15-inch M-Lok rail accommodates modern optics and accessories; full-length Picatinny top rail provides legacy compatibility. Quick-detach points front and rear enable rapid sling attachment. Magpul MOE furniture—including carbine stock, pistol grip, and textured rail covers—provides ergonomic consistency and field durability. The standard mil-spec single-stage trigger and A2 flash hider round out the configuration.

This carbine serves law enforcement patrol units, military support roles, civilian defensive training, and precision rifle sport shooters. The 16-inch barrel length balances velocity in 5.56 NATO with practical maneuverability in vehicle and room-entry contexts. Weighing 8.2 lbs unloaded, the platform remains controllable under extended use while maintaining the rigidity required for accuracy at tactical distances. Shooters choosing the DB15 DB175AK002 gain a USA-made rifle with mil-spec internals, modern ergonomics, and modularity—without proprietary bottlenecks.
