Diamondback Obsidian DB15 Pistol: Compact Power and Precision
The Diamondback Obsidian DB15 represents a thoughtful approach to the modern tactical pistol. This 5.56 NATO platform delivers the ballistic performance of a rifle in a genuinely compact package suitable for home defense, vehicle storage, or specialized applications.
Barrel and Action
The heart of this system is an 11.5-inch Chrome Moly Vanadium barrel finished in black nitride. This proven steel composition provides excellent durability and accuracy. The barrel is threaded and topped with a DB Obsidian muzzle brake, which aids in recoil management and provides a platform for sound suppressors if desired.
The carbine-length direct impingement gas system ensures reliable cycling across a wide range of ammunition. A Mil-Spec 8620 bolt carrier group handles the work, while enhanced controls—including an ambi Warhammer charging handle and Battlearms enhanced bolt catch—make operation intuitive from either shoulder.
Ergonomics and Modularity
The 11-inch M-LOK handguard offers genuine attachment flexibility for lights, lasers, or other accessories. Quick-detach mounts are pre-installed. The Magpul MOE K2 grip provides a secure, comfortable hold, and the SB Tactical SBA5 Brace offers stability and control during firing.
What's Included
Each Obsidian DB15 ships with a 30-round Magpul Gen3 PMAG, ready to deploy immediately.
The Bottom Line
This is a serious tool for serious purposes—built with quality components and thoughtful design.
