Similarities Between Vortex Venom and Viper

Whenever we review the vortex venom and Viper, we look that there are some similarities as well as some difference 

The Venom and Viper red dot sights are very similar.  Here are some of the specification 

  • Weaver / Picatinny Mount
  • 1x Magnification
  • Offered with 6 MOA dot size
  • Under 2″ long.5.Just over 1 ounce

Differences Between Vortex Venom and Viper

Without going deep into the Viper and the Venom’s individual every one review and here in this article we are the differentiate:

  • Venom is also available with a 3 MOA dot Venom has an exposed battery holder for easy changes
  • The base of the Viper is 0.08″ lower in height and 0.1″ shorter in length.

Here To summarize the differences, the Venom is slightly larger than the Viper.  The Venom optics is also available with a smaller 3 MOA dot and the same 6 MOA dot as the Viper. The Venom must be removed to charge the battery. However, the battery for the Viper is easily accessible.

On the other side,

The Venom and the Vortex are both outstanding when it comes to performance level and durability.

They are frequently compared with the equally efficient Vortex Razor red dot because of these qualities.

Since the Venom’s red dot is little larger than that of the Viper, it is probably not suitable for small guns and is a better choice for larger firearms. If you are looking for something smaller, you probably want to go for the Viper.

The Venom optic was much expensive initially, but as the demand was raised on the Viper, their prices equalized.

You probably still search for a Viper at a lower price depending on the seller, but the difference is no greater than $50. 

Both units can be bought for less than $250, making it a reasonable investment for buyers on a budget.

One would say that the Viper is a more convenient option since the two almost have the same build, quality, controls, and battery life, and it is smaller.

Although, the decision will still depend on your personal preferences.

Durability Of The Red Dot

Both Red dots vortex venom and vortex pass with flying colors when the thing comes to their durability.

There is only a little, barely noticeable difference that makes the Viper better.

To put it into numbers, therefore, after review, we scored the  Venom red dot at 93% durability and the Viper at 96%.

We consider maintenance whenever we need to purchase something. This will not be an issue for both red dot because these are equally durable.

Quality Of The Red Dot:

The optics vortex venom and vortex, Venom 3 MOA, and the Vortex Venom 6 MOA are made of aluminum. These are well built and waterproof as well, adding up to their quality and durability.

The Viper also has an aluminum case, but it does not have the same waterproof coating as the Venom.

Therefore, both optics are fairly water-resistant and can deal with wet weather, but the Venom has the edge.

Both optics units last for a long time in terms of batteries. They are also on par when it comes to visibility.

In the end, when we summarize, both Red dots almost have the same quality.

Versatility And Usage Of The Red dot:

The other thing is versatility and usage. The Venom has a great variety of reticle options. Now we will Talk about versatility.

For example, if you install it on a rifle, you can use the small dot for precision shots. If you want the Vortex Red Dot Sight to act as a backup to the sight, you probably easily switch to the large dot.

The Viper, although, only has a large dot, making it more appropriate for smaller weapons.

The glass on both red dots has different layers of anti-reflective coating for optimal performance.

Both units can The Venom has a great variety of reticle options. After all these, we will review and we will make the feature comparison.

Feature Comparison:

Here are some feature comparison that probably helps you to decide between the Vortex Viper Red Dot and the Vortex Venom 3 MOA (or even Vortex Venom 6 MOA);

Here is the list of the comparison features.

  1. battery
  2. Dot lens and glass coating
  3. Mounting height 
  4. Size and weight
  5. Windage And Elevation Adjustment.


The battery is the most important factor when comparing any Vortex Optic sight. Both the Venom and the Viper use CR 1632 batteries, and they both have auto shut-off characteristics after 14 hours. 

The two units last as long as 150 hours when at the highest setting and as long as 30,000 hours when at the lowest. 

It is the same as whenever we are comparing the Vortex Venom with the Razor. 

There is only one difference between the batteries of the two lies in the actual placement.

Some of the type users complain about the poor design of the battery cover, which makes it difficult to close whenever we are replacing the batteries.

On the other hand, The Viper has its battery at the base of the sight. This means that you have to unmount and re-zero the red dot when you need a battery change, taking up plenty of time. 

Dot, Lens, And Glass Coating:

When it comes to both optics, the lens and the glass coating for both red dots vortex venom and Viper are very same.

So, the difference lies in the dot. Red dots are measured using Minutes of Angle (MOA), which usually indicates the dot size at 100 yards. Unless to say, this generally defines a gun’s effective shooting range. The higher the MOA, the larger the dot.

The Venom has 3 MOA and 6 MOA for dot sizes, while the Viper only has the 6 MOA option. So, as explained earlier, the Venom is suitable for both pistols and long guns. However, the Viper is more than enough for Glocks and other handguns.

Mounting Height:

The other thing is mounting height. Their ability to be mounted very low, which makes these two units very famous.

The Vortex Venom is just 0.3 inches higher than the Viper. So for both red dot sights, there will be a bit of difference between the barrel and your line of sight. 

Although, for ArmaLite Rifle platforms, you will require riser mounts for both red dot sights.

Size And Weight:

Whenever it comes to size and weight, both optics are very sane in different aspects. Without their mounts, these both have the same weight of 1.1 oz. 

Once time the mount is added, the Venom becomes 1.6 oz, and the Viper weighs 2.1 oz.  Though none of the Vortex pistol sight is unusually heavy, the Venom is the most lightweight optic.

As we discussed above, there is not so much difference among the two optics when we come to size. As after we viewed the windows, the Viper’s is a little small and vast. However, Venom’s is large and narrow. Therefore, both these optics give very good visibility to all.

Windage And Elevation Adjustment:

Both sights vortex and Viper have windage dials with 1 MOA of adjustment per click. These both optics have adjustable interior elevation as well, which limits to 120 MOA. There is one difference, and that is how the adjustments are made. Windage and elevation adjustment can be made swiftly for the Venom.

It can be very troublesome for the Viper, although. Because of the unit’s design, you will have to loosen two locking screws at the rear of the sight and remove the rear sight to make adjustments.

Vortex Viper Review

Vortex Viper Review

The Viper generally comes with a much lower profile, and it has only a 6 MOA dot option. The 6 MOA dot option makes it easier to get the targets, and the sleeker design makes the weapon more versatile in tight situations.

Due to the Viper’s sleek size, it can co-exist with suppressor height pistol sights. The multi-coated lens and anodized finish are more identical to the Venom, and the optics’ location is under control.

This model uses a CR 2032 battery rather than the CR 1632 in the Venom, making it easier to search on the Market Place.


  • Viper is Parallax Free
  • Viper is a Compact and lightweight Single-Piece framework.
  • Shockproof aluminum construction

Which one to choose? Venom vs Viper

When looking at the Vortex Venom vs Viper, it is essential to understand the durability of the red dot, and their reliability is generally identical because they are from the same manufacturer. Although, each of these red dot sights is designed for various kinds of individuals.

The Venom gives plenty of flexibility for individuals who own both long-range rifles and shotguns as well as handguns. 

Depending on what type of weapons you have, it is possible to acquire a 3 MOA dot or a 6 MOA dot model. On the other hand, the Viper is much more restrictive as it comes only in a 6 MOA dot flavor.

Except for the actual uses of both sights, the huge differences in related characteristics are the night vision systems and the battery replacement methods.

 The Venom’s battery usually can be replaced without unmounting the weapon’s sight, which is better if you don’t get it as a model that you need to move from one firearm to another firearm. 

When all this comes to the Viper, it is a low-profile frame, and it did not give sufficient space for a top-load system. You will have to remove it to perform this action.

As far as the night vision systems are concerned, the Venom also comes with an ambient light sensor that changes the brightness levels, making it better to move in and out of buildings or forested areas. 

The Viper system has to be manually set every time the lighting conditions change, which makes it much more tedious, especially if you do not need to take your eyes off the objects.

Generally, from an entirely functional point of view, the Venom can be extra useful for individuals who usually prefer to use rifles and need sights that will increase their accuracy at a distance of around 50 feet. 

On the other hand, if you own only handguns, then the Viper will be much suited to your requirements. The red dot is very easy to attach and can lower your object purchase time by a solid 2 seconds.

Regardless of which one you select, you have to keep in mind that both of them are only water-resistant. 

Both red dot sights can handle heavy rain and are rather able to withstand being submerged in water for some seconds, but if you leave your weapon in a puddle for various minutes, they probably stop working.
