^^ I did this to my 116 WW. It cleaned up pretty good.

My Model 10 223, I took a buffer wheel on a Dremel to to the bolt body. I won't post pics or pretend to be an expert but it worked. It is possible the surface on the bolt body is nasty where the cocking pin rides. I used my imagination and buffed it.
