My Mossberg 500 has been growing something on the barrel. Actually the growth is at the base of the barrel right where the collar that slides into the receiver meets the barrel. I have cleaned the gun numerous times and after a couple of weeks the white powdery stuff shows up again. The substance wipes right off and doesn’t seem to be harming anything but I was wondering what it is.
The gun is stored is stored in a safe in my garage. I have desiccant crystals in the safe and I keep them fresh. None of the other guns in the safe have anything like it on them nor does the Mossberg have this stuff anywhere else on it. I am thinking that is was some type of flux that was used to connect the barrel to the collar that is causing the problem, have you guys any ideas what it is or how I can get it to stop?
