Hello all. For the first time tonight I disassembled my 10/22 to give it a thorough cleaning.

Along the inside top of the receiver, the charging rod handle has worn the powdercoat down to exposed metal.

I am not worried about rust but it seems strange that this would happen.

Does anyone else have worn down powder coat along the inside of their receivers?

This is a blue rifle, not stainless, and it is fairly new: less than a year old with about 500 rounds through it.

Thanks.
