The Atchisson Assault shotgun, or AA-12, is a fully automatic 12 gauge shotgun. Though a number were demonstrated to the United States Marine Corps in the early 2000's, the design as of yet has not been adopted by any military.
I've known about the AA12 for years, I first saw it on the Discovery Channel on a show called "Future Weapons", then in the first Expendables movie! The way Kyle Myers (FPS Russia) handles it on his video is really cool.
