i have 5 of these scopes mounted on everything from a 1377 to a Ruger 10/22. i love them and they are great scopes for the price. the one mounted on my 1377 is the one in question. i noticed yesterday while outside shooting targets that it has spots on the inside of the objective lens. i am guessing it is where condensation formed and dried. it has been really hot here and i am guessing that going from an air conditioned environment to outside in the heat is what caused it. i tend to leave it out there in the shade for most of the day when i am shooting to keep it conditioned to the temperature.
Crosman said that my only option was to send it in for replacement, but this one is out of warranty. it doesnt seem to affect the "view" when using it and it is very accurate, dead on target actually.
there is a locking ring that holds the objective lens in place. would it be safe to remove that ring, clean the lens, then put it back in without damaging the scope? i dont know anything about how these are assembled so figured i better ask beforehand.
also, what is the best way to get these scopes (any scope) climatized properly when going from cold to hot or vice versa? i do not want this to happen to the other four.
