It was the first successful semi-automatic shotgun design, and remained in production until 1998.
The name of the shotgun designates that it is an autoloader with a capacity of five rounds, four in the magazine and one in the chamber.

Features a plethora of barrel, tube magazine option, stock, and a faster reload perk.
