Used vortex scopes when they first came out not looked at anything they have new. Have you had any problems with them? I was pleased with the one i used. might use one for long range gun so any clarity problems far out? what would be good long range model. i would like turrets on it. I was looking at the vortex on gunwerks website the Vortex Viper HS 4-16x50 LR or maybe the Vortex Viper 6.5-20x50 PA Matte Riflescope i saw on optics planet. any ideas.
