I want to buy an Optisan Viper 4-16x 50mm scope for Field Target, preferably with a brushed aluminum finish. Given the periodic discussion of heat retention affecting scopes during competition, I wonder if the Vipers sold in Europe are sold in either black or silver finish? I would think the silver colour would reflect sunlight and hence absorb less heat than a conventional black finish (on any scope). I see that the very expensive Schmidt & Bender and March scopes are available in brushed aluminum finish. The Optisan scopes are just now gaining popularity in the U.S. While you folks in Europe have had far more experience with the MTC and Optisan Vipers. So I ask about the finishes available in Europe, thinking that Optisan has catered more to your needs. Does anyone here have a silver Optisan Viper, and if so, from where did you buy it?
