Picked up 2 old Redfield Denver Co. scopes that I was planning to send to IronSights and have them freshen both up. Ones a 4x Bear Cub and the other is a 4-12 with the Accurange rangefinder reticle. I didn’t notice till I got home that the 4-12 is missing the screw on on the magnification ring that goes into the erecting system. Anyone know a good place where spare parts can be found or even a parts scope? Checked eBay but no luck. IronSights will go thought the scope but they state they do not have replacement parts.
