Vortex Viper HS-T 4-16×44 Review: Is It a Good Scope?

Vortex Viper HS-T 4-16x44 Review

Are you considering getting the Vortex Viper HS-T 4-16×44 scope but…

Not quite sure if it’s the right fit for you? Want to be sure it’s worth the price you’ll pay?

Then this review is for you. Let me show you how this scope can truly help you strike like a Viper.

Overview of the Vortex Viper HS-T 4-16×44

The Viper HS-T 4-16x 44 from Vortex Optics is very easy to use for target shooting and hunting at extended ranges. 

It has a forgiving eye box and a well-designed second focal plane reticle.

While it is perfect for mountain hunting and long-range applications, I’d say that it may be a bit MUCH for general-purpose deer hunting.

About Vortex Optics

Vortex Optics logo

Vortex Optics is owned by a family of American veterans in Wisconsin.

Founded in 2002, the Vortex Optical Company has succeeded by looking into what its customers REALLY wanted.

By looking at the products currently in the market, they were able to figure out what needs to be fixed and upgraded.

With this practice, they established themselves as one of the leaders in scopes and firearm accessories.

They are also famous for their Vortex VIP Warranty, which promises unlimited, lifetime service for any problems with their products.

While the Viper line is designed in the USA, it is manufactured in the Philippines.

I talk more about this venerable brand in my Vortex versus Aimpoint guide if you want to learn more about them.

Vortex Viper HS-T Review

4.7out of 5

Glass Quality5
Eye Box and Eye Relief4

The Vortex Viper HST 4-16×44 is, overall, an amazing scope. Let’s delve deeper to understand why it deserves this score.

Construction – 5/5

Construction icon

The Vortex Viper HST 4 16×44 is made of a single solid block of aircraft-grade aluminum with a matte black finish to reduce glare.

This strong aluminum also has a hard-anodized finish for further protection and durability.

The lenses themselves have ArmorTek coating, protecting them from dirt, scratches and other damage. They allowed me to keep shooting straight despite the sparks, powder and debris flying around.

All lens elements move smoothly even when bumped with the Precision-Glide Erector System with O-ring. 

The entire scope is shockproof and can withstand recoil, even for long-range applications that involve heavier calibers and more impact.

As the entire scope is O-ring sealed and argon purged, it is completely fog proof and waterproof.

You’ll be hard-pressed to find a more durable scope at this price point! I sure am!

Weight – 4.5/5

Weight icon

The Vortex Viper HST 4-16×44 weighs 1.3 lbs.

While this may seem pretty heavy, this weight is actually quite light for a scope of the Viper’s size.

In my experience, it didn’t weigh down the rifle at all when mounted.

Adjustments – 5/5

Adjustments icon

This rifle scope features maximum windage and elevation turret rotations of 75 MOA.

Its elevation turrets are capable of accurate holds at extended ranges, and adjustments can be made using either .25 MOA clicks or .1 MRAD clicks.

The tactical-style turrets themselves use a precision-force spring system for maximum repeatability.

A great feature of this rifle scope is the CRS zero stop which makes returning to zero quick and easy.

To use this zero stop, all you need to do is uncap the turrets before adding the included shims, which will raise the turrets to return them to zero. 

However, the adjustment features don’t end there!

It also has a radius bar fiber-optic turret rotation indicator, giving you a customizable rotational stop that can be used as a tactile point of reference for turret rotations. 

These are especially useful when making adjustments to drift correction and holdover.

I’ve found that good adjustment turrets are those that move smoothly, and quickly, while producing reassuring clicks. The Vortex Viper DELIVERS!

Glass Quality – 5/5

Glass quality icon

This rifle scope has some of the BEST glass clarity and color fidelity I’ve seen in scopes of this price point.

The glass is treated with multiple coatings for enhanced light-gathering capability and extra-low dispersion. 

It makes use of XD lens elements with XR coating for an anti-reflective finish to help you really see your point of impact. 

All in all, the great glass results in clear and bright image quality for easy targeting and shooting.

I’ve found the sight picture to be exceptionally crisp and clear, almost like watching a movie!

Reticle – 4/5

Reticle icon

The Vortex Viper HS-T 4 16 x 44 has a VMR-1 MOA reticle.

A VMR-1 reticle is a simple, “no-frills” hashmark-based reticle on the second focal plane, giving accurate holds at extended ranges.

While it is most effective for moving targets and wind, I found it to be inconsistent throughout all magnification settings.

Its effectiveness varies with the magnification setting.

I would’ve liked the VMR-1 MOA reticle to be illuminated.

However, the Vortex Viper HST 4-16×44 makes up for this with a reflective quality that helps enhance visibility.

Magnification – 5/5

Magnification icon

The magnification power on this scope is quite incredible for its price. The 4-16x magnification range allows you to shoot at various distances.

You can easily opt for a wide field of view or high magnification with this range. 

When using the 16x magnification level, I’ve found that you can make shots as far as 800 yards. 

It also has a fast-focus eyepiece that allows for a sharp reticle and quick target acquisition. 

Parallax – 5/5

Parallax icon

This comes with a side focus parallax adjustment that allows you to adjust it for your required distance.

However, if you don’t see the point of parallax adjustment, it also gives you the option to just remove it completely.

I didn’t really need it during my test, but I’d recommend keeping it on just in case.

The side focus parallax adjustment is good for 50 yards up to infinity.

Eye Box and Eye Relief – 4/5

Eye relief icon

The Viper HS-T gives you 4 inches of eye relief, which is MORE than sufficient to handle the recoil of most firearms.

The 30 mm tube allows for a forgiving eye box that is good for most applications, including hunting and target shooting.

I found it comfortable even during sustained use!

Warranty – 5/5

Warranty icon

The Vortex Viper HS-T 4-16 x 44 is covered by the famous Vortex VIP warranty, the cherry on top!

You can have it repaired or replaced anytime throughout your lifetime, even with no limit, no receipt, and no questions asked.

Take note that this warranty never runs out.

This means that the warranty will still be in place even if the scope is sold to someone else.

If you want to save some money, you can buy a secondhand Viper and still have the peace of mind of a warranty.

Included Accessories

When you buy the Vortex Viper HST 4-16×44, you will get the following in the box along with your scope:

  • Sunshade
  • Flip-up lens caps
  • Lens cloth
  • CRS shims

NOTE: This does NOT come with mounting rings. 

User Reviews

If you don’t believe what I say about the Vortex Viper HST 4-16×44, let’s look at other reviews from real people who have purchased and used this scope.


This user debated between the Viper HST 4-16 x 44 and the Viper PST but ultimately decided on the Viper HS-T:

“Love this scope! After bore sighting only took about 15 rounds to be dialed in at 200 yards! I would highly recommend this product!! I will for sure be buying more Vortex products in the future for more of my rifles! 10/10 score!” – Anonymous

This reviewer mounted it onto their 338 Lapua and found that it works amazingly despite its affordable price:

“Affordable, yet you can take it to a competition and be competitive with the guys that have the 2k high end scopes. You won’t be disappointed.” – Anonymous

Frequently Asked Questions

Man looking through scope

1. Is the Vortex Viper HS-T 4-16×44 First Focal Plane?


The Viper HS-T 4- 16 x44 mm rifle scope utilizes the second focal plane (SFP).

If you want a Vortex scope without the second focal plane reticle, I recommend their Viper PST.

The Viper PST is very similar to the HS-T 4-16×44, albeit with a smaller magnification range and a first focal plane reticle.

2. What Does HST Stand For?

“HST” stands for Hunting Shooting Tactical.

This means that it is suited for hunting shooting tactical purposes, making it versatile for hunters and long-range and general shooters.

3. What’s the Difference Between Vortex Viper HST and PST?

The HST series is only available in the SFP configuration.

If you don’t want that, I recommend the PST Gen II Series, which is available in both the second and first focal plane configurations.

With the addition of the first focal plane configuration (FFP), the PST Gen II rifle scopes are better suited for tactical and long-range applications.

Additionally, the PST Gen II series has 6 available models, while the HST series only has 2 available models.

The Leupold VX 3HD 4.5-14x50mm is very similar to the Viper HS-T, but with better optics.

It has three reticle choices, and one of them is very similar to the VMR 1 MOA reticle found on the Viper HS-T. 

It also has the same eye relief as the Viper and the same dimensions. 

I have a more complete comparison of Leupold and Vortex as scope brands if you’re interested to learn more.

This is the latest installment in the PST line. It’s perfect for those who want a Viper but don’t want the SFP configuration.

While the Viper PST is extremely similar to the HS-T 4-16×44, it comes with the addition of an FFP reticle.

HOWEVER, note that this has a higher price tag than the HST.

It also has a narrower magnification range as compared to the Viper HS-T.

Bushnell AR Optics 4.5-18x40 (Illuminated Multi-Turret)

This alternative budget scope has an SFP reticle that is very similar in design to the Viper’s VMR-1 reticle with the same great glass.

While most other riflescopes only have one windage correction turret and one elevation correction turret, the Bushnell AR optics scope has five versions of elevation turrets.

Each version can adjust for the bullet drop of various cartridges.

In addition to that, this scope also has a side focus adjustment.

Final Verdict: Is the Vortex Viper HS-T a Great Scope?

YES, it is a GREAT scope! I highly recommend the Viper HST 4-1 X 44, especially for hunting purposes.

It utilizes unique technology for easier and more precise adjustments.

One such technology is the precision force spring system to allow for fine, easily repeatable adjustments.

It also has a CRS zero stop, allowing quick returns to zero in a jiffy.

The exceptional color fidelity, extra-low dispersion, and rugged durability make my images look straight out of a movie!

It is a solid and versatile rifle scope that will serve you well for many years and hunts to come. 

Best of all, it comes with the signature Vortex VIP warranty to ensure lifetime support and service, no matter what!

You’ll be hard-pressed to find a better quality scope with this magnification range and glass clarity at this price point.

I’d go so far as to say that getting the Vortex Viper HST 4 for your hunting rifles is one of the best hunting tips I can give you!
