Diamondback DB15 Obsidian | 5.56 NATO | 16 in | DB1784K791

The Diamondback DB15 Obsidian is an AR-style rifle chambered in 5.56 NATO featuring a 16 inch 4150 CrMoV black nitride barrel and a 15 inch M-LOK anti-rotation handguard finished in Jungle Green Cerakote. It uses a mid-length direct impingement gas system and a shot-peened, magnetic particle inspected Mil-Spec 8620 carrier for the bolt carrier group. For an optic under $1,000 that pairs well with this platform consider a Vortex Strike Eagle 1-6×24 for close-to-mid-range versatility. Suitable applications include disciplined range training and recreational precision or varmint shooting.
