Diamondback DB15 Obsidian | 6mm ARC | 18in | DB1784V001

The Diamondback DB15 Obsidian is an AR-pattern rifle chambered in 6mm ARC with an 18-inch 4150 Chrome-Moly Vanadium barrel finished in black nitride. It is equipped with a 15-inch M-LOK anti-rotation handguard, Magpul CTR stock and MOE K2 grip, and ships with a 26-round metal magazine. The rifle uses a mid-length direct-impingement gas system and standard mil-spec trigger, providing a familiar, serviceable platform for informed shooters. Pairing suggestion: a low-power variable optic such as the Vortex Viper PST Gen II 1-6×24 (under $1,000) suits this rifle for both closer engagements and extended-range precision work.
