So UPS just dropped off a package. I opened it to find my new 380 conversion kit. I ordered it from Graf's. When I opened it I found this. I called Dillon and told them what happened. Their response was it's normal to get a little moisture in the boxes sometimes and for it to rust. He told me to take a little emery cloth to it and call it good. What do you guys think? Should I have demanded a new one, or is a little rust nothing to worry about? I'm not really familiar with rust, I keep pretty good care of all my stuff.
