Yep, the AK SUCKS, its accuracy is horrible (Never designed for accuracy, a 7.62x39mm bullet in the chest, leg, pelvis really hurts). The AR SUCKS also, its SOOOOO unrelible (Granted the gas system is a weak point, but for being around in service since the 1960s, I think its not THAT unrelible, also). The AK works, the AR works.
PS: The AK has been through several evolutions:
AK-47, first a stamped/milled, then totally milled, then totally stamped (AKM). Don't forget the AKS (folding stock) on milled receiver, and the AKMS (folding stock on stamped). The AK-74 has several different evolutions also.
