sun

Does anyone know what sun shade tube fit the Vortex Viper 6.5-20x50 scope? Also, who sells it? Apparently, I tried the 50 mm objective sun shade tube from my Leupy and the threading doesn't fit. Any help is appreciated.

Just curious, if shooting from shaded cover mostly, is the sun shade necessary? Will glare be more of an issue with it off?

Does anyone own one? Local FFL has one for sale. The good, bad, ugly. Whats a good price for one right now? Thanks

I have ordered a new scope and it has not been delivered yet. I am hoping for some time this weekend. In the mean time to keep me occupied while I wait, I am hanging out on the boards. Most scopes that don't cost an arm and a leg usually come with a "stackable sun shade". Why would someone want...
