No, the nicest AK is my genuine vietnamese AK-47 !
Now, to explain how I treat the wood.. well, I'll try to explain but I might miss a lot of english vocabulary.. anyway, I'll try..
1st, I remove the original paint/varnish using a proper paint stripper..
than, I slightly sand what remains of it... when I got the natural wood underneath, I degrease it, just in case.
After that I make the wood swollen slightly using a wet piece of tissue and an iron, or just vapor if your iron can do it. and I sand it again, with very fine sandpaper.. i do that a couple of times until I can't see any scratch anymore..
then, I clean it quickly with a humid tissue...
after that, you may tint the wood first, or directly apply the varnish that you like.. What I chose was a middly glossy oak varnish.. I put 2 different layers every 12hours... sanding it with a VERY FINE sandpaper in between each times..
after that, I polish it slightly one last time with "steel wool" to get a more used and matte finish.. After that, I oil it carefully with some lubricant.. and here you are..
I hope it's clear enough.. unfortunately, it's all my vocabulary allows me.
