OK, I called George at CSMC today regarding the return of my RBL for the stock correction. Asked him about the rust issue on the French gray guns. He told me that there were rust problems on the early guns, so they switched to a different type of coating during the production run. Did not say what that coating is or was, but did admit that a gun that is used a lot would have the coating wear away in 5-6 years. Then? "I guess you'd have to use some oil."
