Diamondback DB15 Carbon | 5.56 NATO | 7-in | SBA3 | DB1913K001

The Diamondback DB15 Carbon is a compact AR-format pistol built around a 7-inch, heavy 4150 CrMoV barrel and a pistol-length gas system. It ships with an SB Tactical SBA3 pistol stabilizing brace, a 6-inch M-LOK handguard, and a 30-round Magpul PMAG, making it a short-package option for shooters who need a compact AR platform. For an optic under $1,000 that pairs well with this package, consider the Trijicon MRO for a low-profile, durable red-dot solution. Typical applications include dedicated range training and short-range vehicle or transport use where a compact platform is preferred.
