Home defense, sure ok... If I honestly need more than five from my shotgun, then I am done anyway.
In other applications. Have you ever had to carry Level IV armor, a sidearm with 45 spare rounds, a M4 with 203 attached and ten full mags of 5.56 with 12 40 mike mike four frags, four bangs, three smokes, a radio, two popups, (water and chow for a day or so) and a shotgun that was only used for breeching doors or scaring the crap out of the bad guys? Yeah the bad guys are scared of shotguns.
Full auto shotgun = a shat ton of weight that is not needed in any application that I can think of.
Sure it would be fun to shoot. But whoever thunked up this piece really couldnt have been building it for any real application. Can you imagine the recoil on that sucker at 200 RPM?
ahh yes the aa12 i dont think that any one could own one except LE but you can dream i love all the little add on shells it has like that granade shell that just looks wicked. also it is from the same people who made the kriss and it uses almost the same tec as the kriss to reduse recoil so there is not much at all.
