The AA-12 is a drum-fed fully automatic shotgun. It's hard to picture a string of words more pleasing to the ears than that, though "Gisele Bundchen needs her rubdown now," comes close.
This video contains a couple NSFW words, so take that into consideration before firing it up. Everything else about this is pure gold, from the hammy narration to the actual performance of the shotgun. (SEE THE VIDEO HERE)
The absence of muzzle rise during the cycling of the gun is pretty incredible as is the ability to control it--even one-handed.
Lastly, heed the warning from the narrator: "Don't try this at home…I am a professional Russian."
