It is extremely curious that teabaggers have suddenly and very belatedly become reticent to call these things assault rifles.
Teabaggers have spent message board careers claiming the 2nd amendment allows them to be prepared to overthrow a tyrannical government by military force if necessary.
If you are going to play Rambo and take on the armed forces of a tyrannical government, surely you would need weaponry that at least approximates military capability in range, ammo capacity, ballistics, , aka assault rifles.
