I have a 9 month old Schmidt and Bender PMII and there is debris of some kind on what I think is the glass with the cross hair etching. It enlarges and shrinks with the reticle as the scope zooms in and out. Is this something S&B would warranty? If so I'm assuming I would have to be sent to them. Does it go to Europe or somewhere in the US? (I'm in the US) Does anyone have any experience with how long it takes S&B to return an optic sent to them for a claim?
