Rebuild for $95, but usually have a very long backlog.
^^^^^ THIS ^^^^^
I have had Redfield and Weaver scopes rebuilt by Ironsightinc. They do great work, but they had my scopes for between 12 and 15 months. If you're not in a hurry, I highly recommend them.
One note, if you decide to have the reticle changed, the German style reticle is really, really, really heavy/thick. Great for short range, low-light, conditions, but too coarse (at least for me) for anything over one hundred yards or so.
