Hey, I tried one of those stocks with a wsar3 several years ago. The place I ordered it from had a picture of an AK mounted in one and I thought it looked awesome. I was also on a Galil, micro Galil kick then.
I ended up just making a big mess out of it. I was never able to get the whole stock mounted up right. I wanted to give up but I had already cut the trigger guard off the AK so I ended up chopping the stock apart and just using the pistol grip and intergal trigger guard. It was functional but it did not look very good. I ended up selling that rifle.
If I had it to do over again I would definitely do it with a pistol of some kind, something with a one piece gas block front sight. A mill would probably help too, I was using a dremmel lol!
