Another entry in the caliber debate? May 1, 2005 Posted by Murdoc The AA12 auto shotgun 5.56? 7.62? 6.8? How about 12 gauge? ACE has info.

Perfect for CQB and ‘Shooting blind’ when someones got a machinegun nest in a room that you can’t shoot through the walls into. For general purpose, You still need something with a ‘point blank to 1000 yard’ capability.
