FYI-There is a person on Ebay from Sturgeon Bay Wi.selling Kahles NIB for too good to be true prices.I believe these scopes to be Gray Market.He has boxes for them but no instruction manual and a copy of the Warranty card.In cases like this the scopes may be authentic ,but since they were sold for German use(No manual in English)and the German warranty is not Lifetime.As a matter of fact you will have NO Warranty regardless of what you are told.The serial No.s on the scope will preclude them from being registered in the US.Soooooo if you have problems,if the factory accepts the scope for repair ITS YOUR DIME!!!!
