Shotguns, 12 gauge (Medium Machine Gun Team, AMSTA-LC-CSIM). In the late 1970s, U.S. Armed Forces took steps to procure a shotgun built specifically to military specifications. The 12 gauge shotgun is a manually operated (pump), repeating shotgun, with a seven-round tubular magazine, ghost ring sights, and equipped with a bayonet attachment and sling swivels. The shotgun is used for guard duty, prisoner supervision, riot control, or any situation requiring the use of a weapon in close quarters. Various models of shotgun are used by all services. The Medium Machine Gun Team supports two models of shotguns; the Mosberg model 590, and the Winchester model 1200.
