AA-M90 Remington

It's an automatic broomstick, what else could you want?

Overview
This shotgun fries a 15 gauge shell and can burn through a 6 round mag in about 3 seconds. With the addition of a rail system, the shotgun could also have sights, grips, and flash lights. The gun can switch between single shot and fully automatic. However, due to it not being pump action, range can be an issue at times.
