At a gunshow this past weekend, I got a Balvar scope that requires external adjustments via the mount. The only marking I see that may indicate what it is is CG9109. The scope has rings but no mount. It is a long, straight tube with no bell on the front and I think it may be a variable. I need a mount and to find out how to adjust it. Can anybody help me? BTW Ipaid $20.00 for it as a project. I want to mount it on my full stockTalo 10-22 to make a sorta replica of a Bavarian.Jeager rifle.
