The Diamondback DB15 Carbon Series in 5.56 NATO is the company’s entry-level AR-15, built with Magpul furniture and a free-float M-LOK handguard (brand part no. DB1718K001). A 16-inch 4150 CrMoV barrel with a black nitride finish feeds a mid-length direct impingement gas system. The 15-inch handguard carries anti-slip texture pads, and the Magpul MOE-PR stock and MOE grip keep the rifle comfortable to shoot. Diamondback Firearms built the Carbon Series for shooters who want the basics done right at a fair price.
