Diamondback DB15 Obsidian 5.56 NATO 11.5" 30+1 Semi-Auto AR Pistol - SBA5 Brace

The Diamondback DB15 Obsidian is a compact semi-auto AR Pistol chambered in 5.56 NATO, built around an 11.5" barrel in a braced-pistol configuration. Part of Diamondback's Obsidian line, this model upgrades the standard DB15 platform with a Cerakote-coated receiver, ambidextrous controls, and a feature-rich handguard ready for accessories.

At the heart of the build is an 11.5" 4150 Chrome Moly Vanadium barrel finished in Black Nitride with a 1:8 RH twist. A carbine-length gas system keeps the action cycling reliably, while the DB Obsidian muzzle brake tames felt recoil at the muzzle. The receiver wears an OD Green Cerakote finish, accented by a Breek Arms ambidextrous Warhammer charging handle for easy manipulation from either side of the gun.

Up front, an 11" M-LOK handguard provides a slim, modular platform for mounting lights, lasers, and foregrips exactly where you want them. Out back, the SBA5 pistol stabilizing brace makes the DB15 Obsidian a compact, controllable package braced at the shoulder, while the Magpul MOE K2 pistol grip delivers proven ergonomics with a steeper grip angle and positive retention.

The package ships with one 30-round magazine, and no iron sights are included so the user can outfit the platform with their preferred optic or red dot. Overall length adjusts from 28.25" to 31", with an unloaded weight of 6.25 lbs. Every Diamondback DB15 Obsidian ships brand new from the factory, ready for duty, defense, or range use right out of the box.
