Introduced in 1961, the Mossberg 500 series of shotguns are hammerless pump (slide) action shotguns. They feature a non-detachable tube magazine below the barrel.
Barrels on the 500 are easily interchanged without tools, so one shotgun can be configured for multiple purposes by swapping in different barrels.
PLEASE NOTE: This item is not for sale, it is an example of a firearm used during the training.
