Hey, everyone. I bought a Bushmaster M4 style rifle over a year ago. I store it locked up in the case it came in. A little while ago I was noticing little red spots on the barrel. I was thinking it was rust. I cleaned it well and put CLP all over it. I took it out again today and it's coming back. Even with a coat of CLP on it. Does anyone know what this is? How do I stop it? Thanks.
I have several handguns and none of them have this problem.
