The Diamondback DB15 Carbon 5.56 Midnight Bronze is a 16-inch AR-15 rifle coated in Midnight Bronze Cerakote (brand part no. DB1718K071). It belongs to the Carbon Series, Diamondback Firearms‘s entry-level DB15 line with Magpul furniture and an M-LOK handguard. The mid-length gas system and 1:8 twist make it a flexible choice for range sessions or a home-defense rifle. The bronze color is the one thing that sets it apart from the black, FDE and green versions of the same rifle.
