I recently bought this Mark 4 12-40×60 with TMR reticle used off the px. Around the objective ring there is a liquid seeping out, it has a blue hue, I was wondering if anyone has one that is experiencing the same thing. This is fairly new when looking up the serial so not sure if they changed something. When I called Leupold about it they said possibly clean it with some alcohol. Just curious if anyone else has seen this. I live in Florida it could've got hot at one point and made the sealant or whatever it is liquefy a bit.
