Have any of you ever had any trouble like this? My AK is firing one round ,ejecting the shell and loading the next,,but not resetting the trigger. If you pull the slide back it will set the trigger every time. At first i thought it was a gas issue ,maybe not pushing the slide all the way back enough to reset trigger,,,,but this is not it,,i had taken the top cover off and put strips of tape across slide area ,to see how far the slide was moving ,,,,it always jamed (pushed ) the tape all the way back to the end.
