Mossberg 500/Vietnam

The Mossberg 500 is a weapon featured in Battlefield Vietnam issued to the US Army and US Marine Corps Assault kits as an alternative to the M16. 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
