the words AK and accuracy do not mix.. Ak's no matter who built them are not designed for accuracy.. weather its a milled or stamped reciever.. 3-4 MOA at 100 yards is about average
Now the milled reciever guns have a slick action and are more ridged than a stamped gun
the real loss of accuracy is from the gas system and its long stroke.. not to mention the short site setup..
