Diamondback Firearms DB15 Combo 5.56 NATO .300 Blackout Flat Dark Earth Cerakote Rifle

Description

Product Overview

The Diamondback Firearms DB15 Combo is a versatile AR-15 rifle package built around a 5.56 NATO lower receiver with a separate complete .300 Blackout upper assembly. Switching calibers requires only separating the upper and lower receivers and installing the alternate upper. Both configurations use 16-inch chrome moly steel barrels with black nitride finishes and 12-inch free-float M-LOK handguards. The forged 7075-T6 aluminum receivers, Magpul collapsible stock and pistol grip, optic-ready flattop design, and 30+1 capacity create a practical setup for training, competition, hunting, and defensive applications.
