The Diamondback DB15 (Diamondback part no. DB1791K001) is a 5.56 NATO AR-15 finished with a distinctive Black Gold lower receiver that sets it apart from a standard all-black build. Diamondback Firearms pairs a carbine-length, medium-contour 4150 chrome moly barrel with a mid-length gas system for smoother cycling, and a shot-peened mil-spec 8620 bolt carrier group for durability. The 15-inch M-Lok handguard runs free-float, and Magpul furniture, including an MOE-K2 grip and a CTR adjustable stock, rounds out a rifle built for range use, home defense, or a distinctive addition to any collection.
