I have found that boresighting an AK at 100 yards works wonders. The AK's sighting systems makes it hard to zero sometimes.     Here is what I do:    -Clamp rifle into a gun stand  -Boresight with lazer at 100 yds.   -Use spotting scope to get you as close as possible  -Finish with your shoot zero    This method will get you 2 to 3 MOA
