Alright--I must be that guy. Just got one Friday, take it apart to clean and lube it--and CANNOT GET THE DAMN COVER BACK ON. I have probably cleaned and re-assembled AK's a few thousand times...I am making sure the tongue and groove are lined up, looks like I am literally millimeters from getting the top cover back in the slot, and I actually have a popped blood vessel from karate chopping it....HELP!?
