Diamondback Obsidian DB15: Versatile Modern Rifle
The Diamondback DB15 represents a thoughtful approach to the modern sporting rifle—built on proven principles with attention to practical details that matter in the field or at the range.
Barrel and Action
At the heart of this rifle sits a 16-inch 4150 chrome moly barrel with FDE nitride finish, providing durability and corrosion resistance. The mid-length gas system strikes an excellent balance between reliability and controllability, while the shot-peened Mil-Spec 8620 bolt carrier ensures dependable function across a wide range of ammunition.

The 7075-T6 aluminum receivers provide a solid foundation, and the ambidextrous safety allows both left and right-handed shooters to operate the rifle intuitively. This attention to ergonomics makes the DB15 accessible to shooters of all experience levels.
Handguard and Furniture
