Description
The Diamondback DB15 Obsidian in 5.56 NATO with a 16″ OD Green finish is a reliable, mid-range AR-15 built for home defense and range use. Since we started stocking this model in late 2024, it’s become a repeat customer favorite for its balance of performance and value. Our staff notes it runs smoothest after a 50-round break-in period.

- OD Green Cerakote finish resists wear and corrosion
- M4 feed ramps for reliable cycling with all 5.56/.223 ammo
- 15″ MLOK handguard accepts modern accessories
- 6-position collapsible stock adjusts for any shooter
