American-180

The American-180 is a submachine gun developed in the 1960s which fires the .22 Long Rifle or .22 ILARCO cartridges from a pan magazine. The concept began with the Casull Model 290 that used a flat pan magazine similar to designs widely used prior to World War II. Only 87 Casull M290s were built, as the weapon was expensive to manufacture. The American-180 is an improved version. A semi-automatic only variant called the American SAR 180/275 is still produced on a custom basis by E&L Manufacturing of Riddle, Oregon.
