Hi! This is my first post to this forum. I used to have a thumbhole Mak-90, but got rid of it a few years ago. I have been missing having one ever since. I came across a Russian parts kit at SG for a good price and I ordered one. Well it came in, but was in nowhere near the condition they advertised.
I decided to keep it anyway. I have been surfing the web, trying to find out as much as possible about a receiver and building it into a shootable semiautomatic. The big problem is, it has a milled receiver and these appear to be hard to find and expensive. I would appreciate hearing from anyone with information on sources for milled receivers and especially from anyone who has built or had built a Russian milled underfolder.
