The Rickard ACW (Advanced Compact Weapon) is a concept submachine gun that was developed and manufactured by Rickard Firearms & Defense. It is the first SMG by RF&D since the WWII-era M35 and M42, although it is not planned to be mass-produced. The ACW is modular, and features a full-length picatinny rail on top and a rail on the bottom, as well as keyhole rail mounts on both sides of the gun. Ultimately, the ACW would serve as the impetus for the RX15 and RX20 assault rifles.
