The AK series of weapons is designed to be a weapon that will work no matter what, no it will not give you sub minute of angle at the firing range but if your fighting house to house it will do the job quite well . As to basic accuracy not much past 250 yards for the average user, for a peasant army thats good enough. And good enough is what the collectivists are willing to pay for .
Owned Norinco's, Galil's, Valmet's and been shot at by an enemy using a Chicom version had he had an AR I wouldn't be typing this...:)
imo...our AR family is a better weapons platform
