Any opinions on Vortex Viper 6.5-20 x 50 versus Viper PST 6.5-24 x 50? I like the Vortex Viper 6.5-20 x 50 because it has turret caps on elevation and windage while the Viper PST 6.5-24 x 50 does not. Even though the PST has stops which are nice, I am afraid my windage turret will unattentionally get knocked off zero in a hunting situation. I wish the PST at least had a turret cap on the wind age if not elevation.. I'm tempted to go with the Vortex Viper 6.5-20 x 50. Anyone else feel the same?
