I currently have two Vortex scopes. My first is a Vortex Viper 6.5X20X50 Dead Hold B.D.C scope mounted on a Remington 700 HBBL, in 7.62mm . My second is a Vortex Viper PST
4X16X50 MilDot mounted on a Tikka T3, 338 win mag. I must say that I love them both. Vortex makes the best optic's for their price point I've found. I also own two Leupold M4 series scopes and would rate the quality of the Vortex glass to be comparable. Excellent optic's with a lifetime warranty.
