From hunting, to recreational shooting, to long range PRS competitions, the Vortex Viper HS riflescope line is the perfect choice. All of the premium optics in the Viper HS line feature a forgiving eye piece and increased eye relief to reduce strain on the shooter's eye and allow for longer sessions on the range or in the field. The use of XD glass and XR fully-multi coated lenses ensures superior light transmission and clarity, and increased windage and elevation travel delivers a greater adjustment range.
