Diamondback Obsidian DB15 Rifle
The Diamondback DB15 represents a thoughtfully engineered rifle suitable for both the experienced marksman and the shooter new to the platform. Built on a foundation of proven design principles, this rifle delivers the reliability and accuracy expected from a modern sporting rifle.
Barrel and Gas System
The rifle features a 16-inch 4150 chrome moly barrel with black nitride finish, providing excellent corrosion resistance and durability. The mid-length gas system strikes an optimal balance between reliability and controllability, reducing felt recoil while maintaining consistent cycling across various ammunition types.

7075-T6 aluminum receivers provide a rigid platform for precision shooting. The bolt carrier group is shot-peened Mil-Spec 8620 steel—the same specification used by military arsenals—ensuring dependable function under demanding conditions.
Ergonomics and Modularity
Ambidextrous controls accommodate both left and right-handed shooters with equal facility. The 15-inch M-LOK handguard offers multiple mounting points for accessories, allowing you to configure the rifle to your specific needs. The MagPul MOE K2 grip provides a comfortable, secure hold, while the MagPul CTR stock delivers adjustable length of pull for proper cheek weld and control.
