Rugged, super-versatile scopes offer a 4x zoom range to make the Viper HS series ideal for any type of short- or long range hunting or shooting. One-piece, 30mm main tubes are purged with Argon gas for superior fog, shock, and waterproof performance. Fully multi-coated lenses feature extra-low dispersion glass and Vortex’s proprietary coatings gather plenty of light to give you clear, high contrast target images – even when light is fading. ArmorTek coating protects all air-to-glass surfaces from scratches and enables easy removal of debris. Side-focus parallax adjustments help to ensure a reliable impact point from 50 yards to infinity. Dead-Hold BDC (DH BDC) reticle includes hash marks to assist you windage corrections and hold-overs out to 500 yards, based on your cartridge’s ballistic performance.
