"The Zoli Model 100 Folding Shotgun in a 20-gauge configuration with a 28"" barrel is a vintage, specialized utility firearm primarily manufactured by Angelo Zoli. The defining feature of this firearm is its single-shot or over/under hinge-break action. By activating the lower lever action release, the barrel folds completely back against the stock, creating a compact profile highly sought after for backpacking and survival use."
