Pawn Shops are typically a great place to get bent on glass,though now and again a guy might fare OK.

Leupold doesn't care who/when bought the glass and is only concerned with their goods. I purposely search for well used specimens,send them to Leupold for a clean & inspect and then rest assured that integrity is intact. It's always a gratis service.

Typically have an elevation turret installed in conjunction,but that is food for an issue seperate.
