I recently acquired a 16x redfield 6400 fine cross hair scope. It is in very nice shape, but the thing is all fogged up. I was wondering if anyone can tell me a value of one that is in good working order and how sought after they are or aren't. Also is iron sight company in CO a good outfit to deal with?

Iron Sight in OK is a good company, but expect to wait 12-15 months to get your scope refurbed.

As stated above ABO is faster and cheaper, but shorter warranty.
