The MC312 Goose semi-auto shotgun in 12GA (2 ¾”, 3”, 3 ½”) is built on a lightweight aircraft aluminum receiver with a machined integral accessory rail for the included Red Dot optics. The MC312 Goose is a gooses worst nightmare. The stock and forend are built out of high-impact polymers for a lifetime of use. The MC312 Goose barrel features a vented rib with a fiber-optic front sight and extended screw choke tubes in a common thread pattern. The overall length of 52-inches and a 30-inch barrel allows the shotgun to swing smoothly on follow-through shots while still having an extended sight plane.
