American 180 Rifle Firearm Manual

The American 180 is a submachine gun developed in the 1960s which fires .22 LR 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 80 Casull M290s were built as the weapon was expensive to produce.

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

The firearm looks a lot like a Tommy gun, which probably contributes to its expense.
