I think I am going to go with the cast and mold method.
I already have some extra picatinny rails, I am going to trim them until they fit.
but I have also noticed that the yugo M92 HG's are curved on top and bottom both front to back and side to side, for that it'll make them a hard
surface to mate to.
I guess I can drive to MGS and pick up a spare set of HG's just in case I mess up.
but now I am thinking, I cant sepperate the parts where the picatinny rails are when doing a cast.
Using the wood I already have, I will sand them down until they are a perfect flat surface, then round them to look stock, then mount the rails to them.
It will be an interesting job to defeat, and I am going to start today.
Watch, as soon as I finish, someone would have made some out of delrin already, and I would have wasted my time.
