The Mossberg 500 is a 12-gauge, 20-gauge or .410 bore pump-action shotgun designed by O.F Mossberg & Sons in 1960.
The Mossberg 500 is uniquely issued to the US Army and US Marine CorpsAssault kits on certain maps. It has a 6 round magazine tube, and fires buckshot shells with potential to kill instantly at very close ranges. After about 20 meters, more shots become necessary to bring a target down. Also, while powerful, the Mossberg's pump action is time-consuming to cycle, making the rate of fire on the Mossberg very low. This makes follow-up shots necessary at longer ranges impractical. The shotgun is an excellent close-quarters weapon, but too specialized in that role to be useful for anything else
