Recently got a Chinese SKS, cleaned off the cosmoline and noticed there are rusts in the chamber:
Looks like some part of the chambered wasn't blued and it rusted. Is that normal? or I simply got a bad luck draw?? Also how would I clean it? I tried soaking that part with lots of gun cleaning oil for half an hour but I still couldn't brush the rust out with a bronze bore brush. Any specific gun oil I can use to remove the rust there?
