Fantastic review!
I got mine just over a month ago and have had only a few problems with it, which hopefully from reading all of the prior posts I may be able to fix.
My stock out of the box was very tight, I did hate the play in the stock.... but it was nothing compared to a Marui underfolding stock, I have a Real Steel Vector Arms underfoling ak47 which I love more than anything..... it has next to no play in it and thats what I want....
After playing with mine and putting close to a bag of bb's through it... the play in the stock is horrid! I let someone use it last weeken
