Diamondback DB1912O061 DB15 | 7.62x39mm | 7″ Barrel

The Diamondback DB15 (DB1912O061) is an AR-style semi-automatic chambered in 7.62x39mm built around forged 7075 T-6 components and a carbon-treated lower. It pairs a 7″ heavy Diamondback barrel and a compact 6″ M-LOK handguard for a short, maneuverable platform suited to range work and field applications. For optics, a compact low-power variable such as a Vortex Crossfire II 1-4×24 offers durable glass and a useful zoom range under $1000 that complements the rifle’s short-barrel profile.
