Features and Performance
The Diamondback DB15 Obsidian Series 5.56 NATO 11.5" Pistol with Brace, Black is an AR-pattern platform built for practical range use, training, and general-purpose carbine work. This configuration puts the important buying details up front, including caliber, barrel length, finish, capacity, furniture, sights, and the overall role of the firearm.
