I have a 581 mini-14 ranch that is my pride and joy. Sending lots of rounds down range and keeping her in pristine condition does not seem possible at this point. The bluing is wearing on the bolt and the inner receiver. I have been touching it up with a bluing pen when I clean it. I shoot my mini regularly so I'm not sure that I need to keep this futile effort up. Should I keep up with this or just reblue it when it gets stored for an extended period?
