Super Shotgun

Oh, this sounds like fun.
Umm.
Well, I mean, it sounds like the military could put these to good use.

American troops are testing a new 12 gauge automatic shotgun in Iraq. Weighing 10.5 pounds unloaded, the Auto Assault 12 (AA12) has a rate of fire of 360 rounds per minute, and uses either an 8-round box magazine (adding 12 ounces to weapon weight) or a 20 round drum magazine (adding 2.5 pounds). Recoil on the system has been reduced to that of a light rifle, due to a sophisticated recoil system. The low rate of fire makes it possible to easily fire bursts of one, two, or three shots and is capable of using and mixing all types of 12 gauge ammunition, from shot to solid slugs, as well as non-lethal rounds.

The ammo sounds even more useful. I especially like the 12 gage firing HE shaped charge rounds.
