Vortex Viper HS vs. Leupold VX-3 – How do they compare?

Optical Enhancements

The exterior lenses of the Leupold VX-3 have been treated with DiamondCoat 2™ – a proprietary coating that was developed by the manufacturer. This coating enhances the levels of light transmission when you look through the scope. It also improves the abrasion resistance on offer; ensuring unruly external conditions (such as harsh weather or exposing the glass to rough contact) will not lead to unwanted scratches. In simple terms, the glass lens will not scratch easily. This ion-assist based element also improves the contrast, brightness, and clarity when aiming at a target. Hunting can consist of many obstacles such as compromised vision from glare, which can negatively affect the quality of your aim if it’s not adequately resolved.

The Vortex Viper HS comes with a trademark solution when coating their lenses against external elements. They do this by implementing XD (extra-low dispersion) glass technology. The inclusion of this feature enhances anti-reflective properties within the lens, as well as increases the potential resolution available when aiming at a target. Improvement of the color fidelity on offer also encourages more crisp and sharp images when looking through the scope. In short, the lenses of the Vortex Viper have been designed to ensure you can enjoy the clearest image possible with the specs involved.

Waterproof and Fog-proof

When planning for a hunting trip, one important element you have to consider is how reliable your rifle scope is – especially in bad conditions. The weather has a tendency of sneaking up on you when you’re least prepared, ruining your trip. Both the Vortex Viper HS and Leupold VX-3 are fog and waterproof, ensuring you can still go out in harsh weather.

The Vortex Viper accomplishes this by the implementation of O-ring seals that are designed to keep out moisture, dust, or any debris from entering the interior of the scope. Argon gas purging is used to prevent any internal fogging from taking place at different temperatures. Leupold, on the other hand, does this objective by the integration of an Argon/Krypton blend that has been proven to eliminate almost all of the effects of thermal shock, as well as the diffusion of gases within the scope. This is a marked improvement from the nitrogen designs that were used by some of the previous models.

Construction and Design

Both the Vortex Viper HS and Leupold VX-3 are designed from a single block of aircraft-grade aluminum, making it hard to break or crack. This is a great advantage when going out hunting since it involves a lot of movement. Sudden movements could lead to various accidents which can subject the scope to sudden and hard impacts. The involvement of one single piece also means that elements such as water and fog will not easily penetrate the device. An anodized finish is incorporated with a matte black texture – which is a refreshing change from the usual rough edges incorporated with most scopes in this price range. Looks might not affect the performance of the scope, but it still feels good to own something with an attractive finishing. It should be noted, however, that the integration of aircraft-grade aluminum maintains a rugged edge that can withstand significant levels of recoil and impact on a regular basis.

One of the attractive features of the Leupold VX-3 is the blackened edges found around the lenses. This outline reduces the light diffusion that would occur when dealing with sunny or bright environments, enhancing the amount of useful light that can reach your eye when aiming at a target. Such issues should never be underestimated, as glare can be a great nemesis when attempting to make a great shot. The erector system incorporated with this option also enhances the holding force that can be enjoyed by up to 30%. Needless to say, a firmer grip when pulling the trigger is something that can greatly enhance the accuracy of your shots. The inclusion of this aspect reduces the backlash experienced from issues such as the recoil after a shot.

The Vortex Viper HS and Leupold VX-3 both come with generous eye boxes that ensure first-timers can reduce the risk of hitting their shot without receiving a black eye in the process. The eye box also allows you to switch targets and aim much faster than would have otherwise been possible.

Customized Dial

One of the main advantages that the Leupold VX-3 holds over the Vortex Viper is the extra step they take to satisfy customers. The manufacturers give you the chance to add a personal touch to your scope by customizing the dial. Every Leupold rifle scope containing “CDS” (Custom Dial System) in its description means that a buyer can get one free custom dial. This opportunity lets you customize your dial in terms of the exact load, velocity, and particular conditions in relation to unprecedented precision. It should be noted that this activity might extend the waiting period for your scope as compared to a normal online purchase. Some of the information you need to provide when requesting a customized dial includes the scope’s serial number, barrel length, caliber, and twist rate. You’ll also need to tell them the type of bullet you will use and its weight, among other things.

Aim and Adjustment

Aim and adjustment determines how efficiently you can change your focus from one area to another. For example, if you’re dealing with a moving object (as is mostly the case when going hunting) you’ll need a scope that can quickly switch its range on an animated object. The Vortex Viper HS has an excellent dial that makes it easy to switch to different aspects such as magnification and sight alignment when working with a tricky target. Turning the dial may not seem like a big deal until you’re faced with a situation where changes need to be made within a few seconds. The cap located on the dial ensures you get a firm grip while turning, so it’s easy to rotate the disc when targeting your quarry. Its fast-focus eyepiece moves from lock to lock in just 1 ½ revolutions, promoting one-handed adjustments.

The Leupold also shares the same features. The configuration of your rifle scope represents a micrometer style. The turret, for instance, maintains the same height throughout the total range. This means that you will be able to enjoy the same levels of visibility when exploring different rotational aspects. It should also be noted that one rotation of the dial can take you through five milliradians or minutes of angle – depending on the configurations of the scope.
