Vortex Optics is a family-own company operated by hunters and competition shooters. With this background, you can trust the brand to anticipate the optic needs of a wide range of shooters. The 6.5-20x50 Riflescope is a popular release from the Vortex lineup. It excels in hunting, target competition, and tactical situations. The tube is machined with computer precision from a single piece of airplane-grade aluminum. The one-piece construction makes this device extremely durable and practically immune to heavy recoil. This sportsman accessory is completely waterproof, shockproof, and fogproof. The Viper is easily adjustable to the individual shooter. The turrets on the Vortex 6.5-20x50 Riflescopes are capped. This is intended as a “set it and forget it” scope. The turrets are adjustable without tools in 1\/4 MOA clicks. Each click can be detected by hand and ear as you make the adjustment. The turret markings are simple and understandable. The Dead-Hold BDC reticle is custom designed to eliminate guesswork. Once your scope is zeroed in at the range, you can return to zero at any time. Simply pull the knobs out all of the way then turn them into position and release. You are now back to the set zero. In fact, the Viper can take countless shots with magnum loads without losing zero. The grayish tan matte ArmorTek scratch-resistant coating minimizes glare and helps act as camouflage, hiding the location of the shooter. Vortex uses a premium dielectric glass and a phase correcting roof prism that provides you with a sharper sight image. This premium high-density glass offers the shooter full sharpness. Therefore, you'll be able to define details of the target at an amazing distance. Vortex further enhances clarity with a proprietary anti-reflective coating called XR. XR anti-reflective coating, with 95 % light transmission, allows you a crisp, clear sight picture even at top magnification. The glass lenses of the riflescope have amazing clarity, even at twilight and at the maximum power setting. At its lowest power, the Viper has an exit pupil of 7.7mm, giving you excellent vision in low-light conditions. These riflescopes use the standard nitrogen flush and fill method. After flushing, anhydrous nitrogen gas is sealed into the interior of the scopes. The O-rings seal the nitrogen in and seal moisture and any contaminants out. The dry nature of the nitrogen prevents any fogging inside the scopes. Its capabilities range from 6.5x to 20x. It is suitable for a variety of long-range shooting, including hunting, tactical, and target applications. With a 50mm objective, the Viper is perfect for extreme range shots. It features a Mil-Dot reticle, which is helpful when it comes to estimating range, windage, and bullet holdover. The reticle is etched into the center of three layers of glass for reliability. The Mil-Dot subtensions are most accurate all the way up to 20x. With a side knob for parallax adjustment, it is possible to change the parallax position with range numbers visible. You can do this while remaining in the shooting position. To clean the Viper lenses, start with compressed air or an optical brush. Use optic cleaning fluid and lint free cloth accessories specifically intended for lens glass.
