Diamondback DB15 5.56 NATO 16" Rifle 30rd Black A2 Stock DB1717K004

The Diamondback DB15 delivers reliable AR-15 performance at an accessible price point, combining proven direct impingement operation with quality components for recreational shooting and home defense applications. This carbine-length rifle features a 16-inch barrel chambered in both .223 Remington and 5.56x45mm NATO for maximum ammunition flexibility.

What Makes This Different

Diamondback's DB15 stands apart from budget AR-15s through its attention to manufacturing tolerances and component selection. The hard coat anodized finish provides superior corrosion resistance compared to basic mil-spec coatings, while the carbine gas system ensures reliable cycling with both .223 and 5.56 NATO ammunition. Factory testing validates function with a wide range of bullet weights from 55 to 77 grains.

Key Features

• 16-inch chrome moly vanadium steel barrel with 1:8 twist rate for excellent bullet stabilization

• Standard AR-15 trigger group with 6-8 pound pull weight

Field performance centers on the reliable carbine gas system that functions consistently across temperature extremes and various ammunition types. The 16-inch barrel length balances velocity retention with maneuverability, producing approximately 3,100 fps with 55-grain ammunition. Competition shooters appreciate the flat-top receiver's optics compatibility, while the collapsible stock accommodates different shooting positions and body types.
