The Diamondback DB15 in 5.56 NATO (brand part no. DB171AK192) is made entirely in the USA, built around the tried-and-true, military-proven direct gas impingement system. Diamondback Firearms machines the DB15’s components in-house on its own CNC equipment and wraps the 16-inch barrel in an M-LOK handguard for mounting lights, optics, and other accessories. This configuration is finished in a two-tone olive drab green and flat dark earth combination, and ships with Magpul-pattern flip-up backup sights. Among AR rifles, the DB15 suits shooters who want an affordable, USA-made carbine without cutting corners on components.
