when the big talk of vortex viper came around i drank the cool aid.I bought a new vortex viper,and a sightron s2 big sky.both were same power.i put them both on rifles and tested them.well it was like comparing a tasco to a leupold.in every aspect the s2 won. the viper had terrible eye relief.the glass sucked at max power and was fuzzy around the edges. i sold the viper rapidly and have never touched another one of their scopes.i had a friend with me and he had a nikon buckmaster on a 220 swift that i thought was a better scope than the vortex.
