before I went on vacation last week I ordered a Yugo M53 from Sarco.Just got back tonight and checked it out first thing. Barrel looks frosted but may just need cleaning. Some parts look twisted and others look like they were taken apart with an air chisel. I plan on cleaning it up this Sunday after I get back from the gun show. I will take pictures and maybe someone can tell me if what I have is rebuildable or if I need to send it back. Hope I don't have to send it back.
