The Ithaca Model 66 Super Single 12 Gauge is a unique, vintage single-shot shotgun that was manufactured by the Ithaca Gun Company between 1963 and 1978. What makes it famous-and highly memorable for collectors-is its distinctive lever-action look. While it has a bottom lever like an old-school cowboy rifle, pulling the lever does not chamber a new round; instead, it breaks open the single-barrel action so you can manually load a single shell.Key Specifications & FeaturesAction: Single-shot, break-open mechanism activated by a lower lever.Chamber: Most 12-gauge models feature a 3-inch chamber, allowing them to shoot both standard 2 3/4-inch and 3-inch shells
