Diamondback, Db15 Obsidian, .300 Blackout, 10 inch, 30 round, Flat Dark Earth

The Diamondback DB15 Obsidian pistol brings the DB15 series into a compact, duty-capable .300 BLK package with a 10" threaded barrel for suppressed or short-barrel configurations and a 9" M-LOK handguard that accepts lights, offsets, and sling mounts for low-profile optics and accessory placement; the SBA5 pistol brace and Magpul MOE K2 grip provide familiar ergonomics for shooters transitioning from full-size AR platforms, while the flat dark earth finish resists wear in field use. Built on the Obsidian model line known for durable mil-spec components and reliable direct-impingement operation, this semi-auto pistol is serialized and FFL required, making it suitable for tactical training, home defense where maneuverability matters, and suppressed hunting applications with subsonic loads in .300 BLK. The threaded 10" barrel supports improved velocity with supersonic ammo or clean suppression with subsonic rounds, and the 30-round capacity offers extended range sessions without frequent reloads. If you're evaluating compact AR-style pistols for range work, close-quarters drills, or short-range big-bore performance, the DB15 Obsidian balances handling, modularity, and caliber versatility in a shooter-friendly package.
