Unique Features

There are a few unique features of the Vortex Viper 4-16x44 that make it stand out from the plethora of options available on the market. 

Let’s look at them in a bit of depth:


The Vortex HST 4-16x44 has a solid construction and is made from aircraft-grade aluminum. This scope has a single-piece, 30 mm one-piece tube that allows maximum internal adjustment.

The scope body is O-ring sealed and argon-purged, which makes it fog and water-proof.


The quality of the image that an optic produces is a reflection of how well or how poorly made it is. The optics are a major aspect to consider when selecting the hunting scope to invest in.

The Vortex HS-T 4-16x44 has a multi-coated glass lens to enhance resolution and produce a clear and bright image.

This multi-coated lens construction optimizes light transmission to make the most of the lighting conditions.


The Vortex Viper HST 4-16x44 has a VMR-1 MOA reticle that works exceptionally well for target shooting at extended ranges as it is a hash-mark-based reticle with a second focal plane.

This helps maintain the reticle appearance even at longer ranges despite the magnification.

The VMR-1 reticle works wonderfully well for windy conditions and for targets on the move.

However, the Vortex Viper 4-16x44 is different from night vision scopes. The focal plane reticle isn’t illuminated, which might be a slight problem for those who use their hunting rifles in the night. 


The Vortex HST 4 16x44 comes with a number of different accessories that add to its value. In the package, you get a 4-inch sunshade that most brands provide at an extra cost.

There’s also a good-quality leather cloth to clean your scope’s lenses. You also receive protective lens caps in the package.

Glass clarity

Glass quality and clarity are two of the most important characteristics of a fantastic scope.

After all, if you have a high-end model but are unable to see your target through the glass, your scope will be essentially useless.

The Vortex Viper HST 4-16x44 not only offers a crisp and clear image, but its glass also boasts a multi-coated lens and an anti-reflective finish for improved light gathering capability.

This lens further ensures extra-low light dispersion, improving the color fidelity and resolution in your sight.

The Vortex Viper 4-16x44 further offers excellent clarity throughout the zoom range and powerful 16x magnification, allowing you to make precise shots as far out as 800 yards.

The Vortex Viper HST Scope Variants

vortex viper hs t review

The Vortex Viper HST 4-16x44 scope is available in two different variants. The difference between the two is of the objective lens diameter and magnification.

The bigger the objective lens' diameter, the greater amount of light it will gather, resulting in a brighter image.

So, in low lighting conditions, it is better to get the Vortex product with a 50 mm objective lens. The other variant has a 44 mm objective lens diameter.

Similarly, one variant has a magnification range of 4x to 16x, whereas the other has a magnification range of 6x to 24x. For long-range shooting, the variant with a higher magnification is the better choice.

Troubleshooting the Vortex Viper HST 4-16x44

Here are some common queries people have regarding the Vortex Viper HS T 4 16x44:

What Kind of Warranty Does Vortex Viper HST 4-16X44 Come With?   

The Vortex HST 4 16x44 comes with a VIP warranty, which is basically an unconditional, unlimited, and lifetime warranty. If your scope is defected or damaged, Vortex Optics will replace or repair it without any additional charge.

If the company is unable to repair the scope, it will replace it with another one in perfect working condition.

How to solve sighting-in problems

If you encounter problems with sighting-in, the issue may not be with the scope but with how you have mounted it.

So, make sure to use the correct rings and check if the base is in the right orientation.

Also, note that the base screws and rings should be tightened well when mounting the scope.
