The Viper's Precision-Force Spring System is a patented system that uses an ultra-performance copper alloy / cobalt-beryllium spring. Not only does this greatly increase the fatigue life of the erector support system over more commonly used materials, but changes in spring pressure over time are virtally eliminated because the spring maintains a constant force throughout the entire range of motion. And, most importantly, windage and elevation adjustments are consistently smooth thanks to the spring's resistance to galling against the erector tube.
MAG-View adjustment lever allows rapid, easy changes in the magnification—even when you're wearing bulky gloves. Raised, rear-facing numbers make the referencing fast.
Fast focus eyepiece is quick and easy to use.
Pop-up dials let you easily set elevation and windage back to zero.
Audible clicks are easily counted for fast, precise adjustment of elevation and windage.
The Viper's Precision-Glide Erector System features premium-grade fluoropolymer teflon resin bushings that provide exceptional resistance to stress cracking, temperature change, corrosion, and friction-induced wear. In addition, these bushings have an ultra-low coefficient of friction for the smoothest possible operation of the magnification adjustment.
4-12x40 riflescope is ideal for Big Game, Long Range, Predator/Varmint, and Target hunting.
V-Plex reticle is the single best all-purpose hunting reticle intended for a wide variety of hunting applications.
Side Knob Parallax Adjust provides quick and easy parallax adjustments with range numbers visible while in the shooting position.
Watch the Vortex Optics Independent Riflescope Test, a two-part video, and see how well the Viper performs after being subjected to water submersion, freezing temperatures, and the abuse of heavy recoil.
