Vortex Viper 6.5-20x44 PA Riflescope
Dead-Hold BDC Reticle
Shrugging off recoil, moisture and darkness with impunity!
The Viper's status as a premium riflescope won't be as easy to shake. Discover a riflescope with incredible performance features like 95 percent light transmission and premium, fully multi-coated optics for stunning detail and color differentiation – delivering all this and more at a price that should have pulled a few more hundreds from your wallet than it did.
X-Factor Vision
Precision optics feature our exclusive XR anti-reflective coatings for exceptional image clarity, and XD premium high-density glass to provide the edge-to-edge sharpness needed to differentiate details at any distance.
XD (Xtra-low Dispersion) glass objective lens elements of extra-low dispersion glass enhance image resolution and are carefully selected and precision-crafted to exacting standards for true-to-life images of startling clarity and color accuracy.
XR coatings deliver incredible image detail with extremely high resolution and light transmission. Fully multi-coated, scratch-resistant coatings eliminate annoying, image-degrading reflections and offer extraordinary brightness for a lifetime of trouble-free lens protection.
- 6.5-20x44 riflescope is ideal for Long Range, Predator/Varmint, and Target hunting.
- 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.
Game-changing performance features.
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.
- Side Knob Parallax Adjust provides quick and easy parallax adjustments with range numbers visible while in the shooting position.
- 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 fiction-induced wear. In addition, these bushings have an ultra-low coefficient of friction for the smoothest possible operation of the magnification adjustment.
On track for a long life.
Vortex engineered the Viper riflescope to stand the test of time and rough abuse. The solid one-piece main tube of the Viper is incredibly tough and constructed out of 6061 T6 aircraft-grade aluminum. Vortex goes even further and purges the Viper with the highly-prized argon gas, targeting corrosion in an unchallenged way:
- Argon gas does not absorb or react chemically with water.
- Argon gas eliminates internal fogging.
- Argon gas maintains its protective properties over a wider temperature range.
- Argon gas does not diffuse as quickly as other elements, extending the service life of the optics longer.
