Both of you did very good job at reviewing this AK.

I am just wondering though how well the butt cover will hold after many times of unscrewing and screwing back in to the wood for charging/ replacing the battery?
It is really hard to see if there is a metal nut in that butt screw. Is there?
I found this and here is the sample picture of RS Type56-1 butt stock (The screws place look more durable with brass nut in there)
Thanks for the reviewing guys..
