Statistically the AK is the weapon of choice for most armed groups in the world, so technically that is correct. Whether Obama knows the difference between an assault rifle, assault weapon, select-fire and semiautomatic, and AK and everything else is not likely.
Sadly, the same can probably be said about the folks who will come up with whatever new gun laws get pushed. Why can't competent people make laws regarding the things they know...
... but then again, I'm talking about politicians, so competency in anything is not really in the cards.
