AR Rust or copper/brass problem?
After the first time I shot my AR, I used a copper brush to brush the bolt. An when I did, the bolt turned copper color. As if the copper was rubbing off on the bolt. And I also noticed that the lip of the extractor had what looked like brass on it. Now when I look into the bolt & the extractor, it kinda looks like rust... Smooth rust, instead of flaked rust... Is this rust or copper/brass? And is it normal for brass and copper to come off on a bolt so easily? I think I'm just paranoid but I need help... Thanks in advance.

What does copper solvent or ammonia do to it? If it turns green, it is copper. If it stays the same color, it is rust.
