This next weapon has been in production and has been redesigned since 1972. You're looking at the Atchisson Assault Shotgun, aka Auto Assault-12 or the AA-12 for short. First designs made it look like an M16 that fires 12 gauge rounds. But now with the new MPS version (seen above), it looks like it's ready to raise some hell. It uses either 8 round mag, a 20 round drum or a 32 round drum that can fire traditional buckshots or slugs and it even fires the deadly Frag-12 rounds, which sounds like 20mm grenades... still looking into that one. I've seen this on Future Weapons, and I must say, I'm impressed what it can do in an "operators" hand or mounted on unmanned vehicles.
