The front sight has been polished and readied for bluing, I cannot hot blue it as it has a brass bead, which I have been told will be damaged by the salts (even though I have successfully blued parts with brass inserts before, I don't want to push my luck)
I will have to cold blue or rust blue it



also note that the front edge of the sight is not highly polished (about 400 grit in this case). you don't want anything in your sight line polished and possibly reflecting light.

I finished polishing the rest of the bolt and reassembled it
