So, I am ever grateful for the immense knowledge and experience on this site. I tried to search for an answer to this issue but no results were retrieved (I might suck at the search engine). On 2/16/16 (My birthday) I purchased a Bulgarian Circle 10, Arsenal SLR 107 FR AK 47. I am really familiar with firearms. I have this AK and I really like it, like more than most of the AR's I have built or own. I love the length of pull, the stupid iron sights, the industrial nature of the tool. I really do love it. So I go out today and shoot with my father in law, and come home to clean it. I use Gunzilla to clean everything, it works great and while I am cleaning the barrel (which is chrome lined) I notice that the paper towel that I have the bolt and op rod on are turning purple. I grab the bolt and it is sticky, I mean like really sticky. So I try to wipe it off and the black finish starts coming off. Underneath is a grey metal (which is fine by me), and the op rod does the same thing. Again, I know these things can run forever without so much as a squirt of oil, but I think it is black paint. Like literally the black finish just rolls off, a sticky bubbled up finish. Some of it stayed on but most just came off. So, I have a guy here local that is a certified CereKote dealer/applier and can easily have him do the whole damn gun (including the bolt and op rod). I am just wondering, have any of you ever heard of this? By the way, yes I know what cosmoline is and no, it is not cosmolibe coming off. Thanks a million for the responses. Have a great week.
