Viper 4-12x40 PA Riflescope

Effortlessly shrugging off recoil, moisture and darkness! The Viper's status as a premium riflescope won't be as easy to shake. Discover a riflescope with incredible performance features like premium, fully multi-coated optics with 95 percent light transmission, heavy duty Precision Force spring systems and the glass smooth Precision Glide erector system—delivering all this and more at a price that should have pulled a few more hundreds from your wallet than it did.

4-12x40 riflescope is ideal for big game, long range, predator/varmint, and target applications.
Dead-Hold BDC reticle has a customized design that helps eliminate guesswork on hold-over and windage corrections. Good for any hunting or shooting at varying ranges where estimating hold-over would be a concern.
Side knob parallax adjust allows quick and easy parallax adjustments with range numbers visible while in the shooting position.
