The Diamondback DB15 (brand part no. DB175AK063) is an AR-15 chambered in .223 Rem/5.56 NATO, finished with a Multicam receiver for a rifle that stands out from the usual black-and-tan crowd. A 16-inch threaded barrel pairs with an A2 flash hider, and the B5 Systems Bravo stock, grip, and foregrip give shooters a consistent, adjustable furniture set across an overall length of 33 to 36 inches. Front and rear QD sling points plus a hand stop round out a rifle built for comfortable, controllable carry. It ships with a 30-round Magpul Gen M3 PMAG with a window for a quick round count check.
