The Viper 6.5-20x44 is built on a 30mm main tube with a hard anodized finish providing a rugged, tough hunting riflescope. The Dead-Hold BDC reticle is good for any hunting or shooting 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.
