I go to the gun store and they have a lot of class 3 guns but i seen only M16/ar15 guns, short rilfes, and short shots guns. Are they any other full auto guns they someone with a class 3 could buy? also is there still these guns around or could be found: striker 12 special purpose shotgun,cobray 11 gun,GLOCK 18C,tavor 21, and Intratec ab10? i am just asking becuase the only class guns i have seen for sell are M16 and short shotguns and i have hear of other guns that are class 3 but never seen one.
