Diamondback builds its DB15 line in the United States as a no-frills, genuinely usable AR-15, and the Obsidian series keeps the spec sheet where it counts: a 16 in. barrel, a free-floating M-LOK handguard for lights and grips, a mil-spec-pattern lower and a flat-top receiver ready for any optic.

Chambered in 5.56 NATO, it handles .223 Remington as well, which makes ammunition easy and inexpensive to find. It is a solid platform for home defense, training, predator hunting and general range use, with the entire AR aftermarket behind it.
