Diamondback DB15 | 6.5 Grendel 18″ | DB1732N001

The Diamondback DB15 is a semi-automatic modern sporting rifle chambered in 6.5mm Grendel with an 18-inch mid-length barrel and a 15″ M-LOK handguard. It pairs a forged 7075-T6 upper and lower with a Magpul CTR adjustable stock and Magpul MOE-K2 pistol grip for familiar ergonomics and modularity. The rifle is built with a mid-length gas system and a shot-peened Mil-Spec 8620 bolt carrier for serviceable durability. For optics, this platform pairs well with a Vortex Viper PST Gen II 1-6×24 for low- to mid-range precision and quick target acquisition while remaining under $1,000.

Applications for this rifle include precision-oriented long-range shooting and centerfire hunting where the 6.5 Grendel cartridge offers an extended envelope over common intermediate cartridges. The 15″ M-LOK rail and threaded muzzle provide options for accessory mounting and muzzle devices.
