"Quality features and superior value. New to the U.S. market, the ****** magnum semi-auto shotgun incorporates all the features of expensive European self-loaders at a remarkable price.
****** semi-auto shotguns are gas operated and are chambered for 3" or 2 3/4" shells. Barrels are made of nickel-chromium-molybdenum steel with additional chrome plating internally and a ventilated anti-glare checkered rib on top."

Found the above. This gun was priced at $350.00, made by HOWA. Looks like there's one for sale on gunsamerica.com
