The Auto Assault-12 (AA-12) is an automatic 12-gauge shotgun that can fire 300 rounds per minute and is recoilless. Basically, it's incredibly powerful and you really, really, don't want to be at the wrong end of it. It's also claimed that it requires no cleaning or lubrication ever, although I'm not really sure how that would work. In any case, you don't really care. What you care about is that it's a big gun and makes loud noises and busts stuff up real good. look forward to killing many terrorists/Russians with this in Call of Duty 5: Are You a Bad Enough Dude to Rescue the President?

@drewheyman: Max effective range for a 12 gauge 2 3/4" slug is about 100 yards, With a sabot it jumps up to around 125 yards. But even the top of the line sabot has about 3' of drop at those ranges and this weapons sighting system is a scaled up version of that found on the M-16.
Also I just found another article claiming it has an effective range of 200m, not 150m.
I call utter PR bullshit on this.
