An MPS AA-12, an example of an automatic shotgun

An automatic shotgun is a shotgun that fires in fully-automatic mode. Generally using actions quite similar to most other automatic weapons such as gas operation, recoil operation and blowback, automatic shotguns will continue to fire until one of two things happen; the trigger is released or if the shooter expends all ammunition.

A number of these shotguns are capable of select-fire, although this does not mean they are all capable of select-fire. While shotguns can chamber a large variety of ammunition, automatic shotguns are slightly hampered in this respect as the shot will need to have sufficient power to cycle the action reliably; this means that low-powered rounds usually cannot be used (this includes non-lethal ammunition like beanbags).
