The Mossberg 500 family of shotguns is perhaps one of the most popular and versatile American-made pump-action shotguns ever produced. Mossberg 500’s were made with a wide assortment of barrel and magazine lengths, finishes, stock shapes and accessories. As one may discern, this particular model is for “Less Lethal” purposes; meaning it is solely equipped to fire less-lethal rounds (bean bags, rubber shot, etc) by law enforcement agents. Riot police are typical users of such less-lethal munitions delivery systems. Like most other Mossberg 500s, it is a magazine-fed, manually operated (pump action) smoothbore gun.
