About this item

• The Viper 6.5-20x50 is built on a 30mm main tube with a hard anodized finish providing a rugged, tough hunting scope. The Dead-Hold BDC reticle is good for hunting at varying ranges where estimating hold-over would be a concern.
• Incorporating our premium, fully multi-coated, extra-low dispersion lenses brings excellent resolution and color fidelity. The XR coatings provide enhanced light gathering capability while Armortek coating protects the lenses.
• Capped reset turrets allow quick re-indexing of the turret to zero after sighting in the scope. Side knob parallax adjust allows quick and easy parallax adjustments with range numbers visible while in use.
• The fast focus eyepiece allows for quick and easy reticle focusing while the MAG-Bar allows rapid, easy changes in magnification.
• The Viper 6.5-20x50 riflescope is ideal for long range, predator/varmint, and target applications. O-ring sealed and argon purged, the Viper provides fogproof and waterproof performance.
