The Diamondback DB15 in 9mm Luger (brand part no. DB1418P071) is a semi-automatic pistol-caliber carbine built around a carbine-length, medium 4150 chrome-moly barrel with a 1:9.5-inch twist, running a mid-length gas system through a shot-peened Mil-Spec 8620 bolt carrier. Diamondback Firearms finishes the receiver in Midnight Bronze and wraps the barrel in a 15-inch M-LOK handguard, using a Diamondback Carbon lower receiver for reduced weight. The carbine fits a Magpul MOE-K2 grip and a Magpul CTR stock, tops the muzzle with a flash hider, and uses a thumb safety, feeding from a magazine with a 32+1 capacity. Among AR-platform rifles in the AR rifles category, the DB15 favors 9mm shooters who want a lightweight carbon-lower build in a distinctive Midnight Bronze finish.
