The VORTEX Viper 6.5-20x44 PA Riflescope, Dead-Hold BDC Reticle, Matte Black (VPR-M-05BDC) is ideal for big game, long range, predator/varmint, and target applications. This model scope features a side parallax, which uses an adjustment mechanism on the left side of the riflescope to fine-tune focus for the purpose of reducing parallax shooting error.
The Viper riflescope offers 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.
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.
XD (Extra-low Dispersion) glass objective lens elements made 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.
The Precision-Force Spring System uses an ultra-performance copper alloy/cobalt-beryllium spring - greatly increasing the fatigue life of the erector support system over more commonly used materials. The spring maintains a constant force throughout the entire range of motion - virtually eliminating change in spring pressure over time. And, most importantly, windage and elevation adjustments are consistently smooth thanks to the spring's resistance to galling against the erector tube.
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.
Vortex engineered the Viper riflescope to stand the test of time and rough abuse. The solid 30 mm 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.
The customized design of the Dead-Hold BDC reticle helps eliminate guesswork on hold-over and windage corrections. It is good for hunting and shooting at varying ranges where estimating hold-over is a concern.
The Viper 6.5-20x44 PA Riflescope comes with removable lens covers, dust cloth and the VIP Unconditional Lifetime Warranty.
