Rivets look to be good and tight and round. I'm not sure what the value would be with the end product of a Maadi rebuild.Crap should have read further!! This may be a great time to learn to build an AK, You can get a nodak spud receiver for like $100, proper bolt will be cheaper as will the Mag catch. I really enjoyed the process and learned a lot about the platform. Let me look ,I may have a mag catch and the ejector part in my bin of parts. Are the receiver rivets loose any where?
