Ok, this is a first for me, not have I heard of this happening before. I picked up my M1A that I had pawned to my buddy several years back so I could pay some bills today. Hes had it sitting in his safe for the past several years and got it out to return it to me today. It has a BSA Catseye scope on it that had a rubber armored finish on it. Well that rubber finish has turned to goo, literally. Anywhere you touch the scope, you get a Black gooey substance all over you and anything it touches. Ive had scopes with this type of finish before and never had this problem ever. Even here in our humidity. Has anyone heard of such a thing or had it happen to their scope? Im gonna try and use some cotton balls and alchohol to get it off, WD40 on a rag, goo gone, something. I asked him if his safe was out in the garage, but it is inside the house. Thought maybe the heat did it. Anyways, I got my baby back for Doomsday.
