| As I was cleaning my rifle last night, I noticed a gray film on the inside of my CMT upper. The gray film wasn't solid, the corners and other places of wear were black. As I used my Hoppies soaked Q-tip to clean around the gas tube and inside the receiver, I noticed the black parts getting bigger. It seems that this film is coming off. What is this film for? Is it supposed to come off? What should I do about it? I don't really want to take my upper apart to send the rcvr back, but I guess I will if I Have to. I'll get some pictures tonight if anyone is interested. Thanks. |
| That gray stuff is a dry film lubricant. It will come off with some lubes and cleaners. It is no big deal. I cleaned all of mine out with brake cleaner once it started to come off on the inside. It won't hurt anything, you still have hard coat anodizing underneath it. |
