Features Vortex Venom vs Viper Red Dot

1. Glass clarity and Reticle

Venom: For a crystal-clear view, the glass clarity of the Vortex Venom is made of fully multi-coated lenses. The vortex venom provides a premium wide-field lens and a multi-layered anti-reflective coating on these lenses that enhances the transmission of light. Because of the clarity offered by the vortex optics, the vortex venom red dot sight is ideal for use in both direct light and low light environments. With ten brightness levels available for the Reticle of the Vortex Venom red dot sight, you won’t have trouble maintaining your ability to see clearly while adjusting the brightness level. That’s why my favorite functions are the power and dot intensity control systems on the left side of the vortex venom red dot sight. Additionally, to protect the venom red dot, vortex optics provide a lens cover known as “Armor Tek” that prevents scuff marks, dirt, and many other wreckages from reducing the clarity of glass.

Viper: The fully multi-coated lenses on the vortex viper red dot also provide clear vision. Similar to vortex venom, Viper also has a protective lens cover called “Armor Tek” that stops scrapes and other undesirable materials from impairing glass clarity. Even though the automatic mode of the Venom is more useful, we can’t deny that the low height of the Viper makes it easier to quickly acquire the target, which enhances both my aim and speed of shooting.

In comparing the Vortex Venom and Viper red dot sights, both of these optics have extremely good glass clarity and reticles. Still, I preferred Venom’s power and dot intensity control mechanism. I was also able to choose the level of brightness I needed for any lighting situation due to the illumination’s simplicity of control.


The winner is the Vortex Venom due to its superior clarity and pinpoint accuracy.

2. Brightness Adjustment

Venom: The luminosity can be adjusted in the vortex venom up to ten levels by pressing the “Up arrow” and “Down arrow.” Additionally, it has an automatic mode that modifies Venom’s brightness in response to ambient light. That’s interesting, and perhaps it is for competitive shooting in the daytime. I would suggest sticking with manual mode for strategic use. The illumination around you, not the illumination your target is in, determines how the Reticle will move. At night, a weapon-mounted light can blur a reticle, and the automatic configuration won’t respond accordingly because the light is in front of the optic. The dot may be difficult to see and require manual adjustments if you are aiming in a dark environment while in a bright environment or vice versa. There are two models of Venom, one with a 3 MOA reticle and the other with a 6 MOA reticle.

3 MOA for > Handguns

6 MOA for > Long guns

Viper: The Viper has a luminance adjustment setting up to 10 levels, just like vortex venom. However, it lacks an automatic mode, so you must manually adjust the brightness by the light source. The Viper only has a 6 MOA dot out of the box, which makes complete sense for an optic specifically for pistols.

Both the vortex products: vortex venom and vortex viper red dot, have ten-level brightness settings, but despite sharing the same total, their actual effects differ. Compared to the Viper, the Venom offers a much brighter red dot. Both are useful in bright light conditions, but the vortex venom can intensify the brightness.

3. Eye relief

Venom: With Venom’s nearly limitless eye relief and an automatic mode, I discovered the rapid sniper scopes I was searching for in this optic. I managed to aim and shoot without getting a cheek lining while quickly recognizing my target.

Viper: The unlimited eye relief offered by the vortex viper may or may not be beneficial, depending on the circumstances. I concluded that I kept reaching for the high-rise mount because of this optic’s low-profile design (which is perfect for cut-out slides and handguns). Its eye relief depends on the mount being used, but it can also be flexible based on the user’s preferences.

There is no doubt that both red dot sights offer limitless eye relief, but it depends on various factors, such as my preference for versatility and the vortex viper’s hit-or-miss performance. I enjoy the eye relief of this optic when I use a higher mount. But when I use the Viper in its limited configuration, I’m not as fond of it.


The winner is Vortex Venom red dot sight due to its automatic mode and unlimited eye relief.

4. Durability and weight

Venom: The vortex venom red dot sight is shock-proof and water-proof. It is, therefore, appropriate for any setting and climate. Additionally, it has a lens-protecting cover (the Armor Tek) that prevents oil, scuff marks, and unwanted material from impairing its features and functions. The Venom’s superior durability characteristics can compete with the “Vortex Sparc 2” or “Vortex Strikefire 2’s” difficult strength. I adore how it is small, light, and incredibly durable.

Viper: The vortex viper is equipped for action due to its difficult durability and ability to withstand any climate. Moreover, it is water-proof and shock-proof and has a lens-protecting cover, the same as Venom (the Armor Tek), which guards against any type of humidity, dirt, and other particles from diminishing the Viper’s performance.

Vortex Venom wins the battle.

5. Source of power

Venom: The battery type for the Vortex Venom is CR1632. Depending on the luminance configuration, the lifespan of this CR-1632 battery varies from 150 hours to 30,000 hours. The battery has a range that extends to 30,000 hours on low configurations and up to 150 hours on the highest configuration. Venom’s battery compartment does not particularly enlighten me because of how snugly it is packed.

Venom’s snug-fitting compartment has only ever caused me one issue during operation. The battery fell out of the optics while I was firing bullets, rendering them useless because the screw holding the battery compartment closed became open and free. I then had to search for the battery, which I eventually did.

vortex viper battery life: A CR2032 battery, with a lifespan of 150(on highest brightness configuration)–30,000(on low brightness configuration) hours, powers the Vortex Viper. An integrated battery compartment is present in the base of the optic on the viper. To switch out the battery, you must first unmount the optic, mount it again and zero it. The Venom is remarkably more practical, but this architecture slightly enlarges the optic.

Battery TypeBattery lifeBattery PlacementBattery sizeBattery Cost
VENOMCR-1632150 TO 30,000 hoursTopSmallCheap
VIPERCR-2032150 to 30,000 hoursBottomLargeExpensive

Here, the cost of batteries is the distinguishing difference that has an impact on you. One of the key distinctions between the viper and the venom is where the batteries are placed. The venom’s top cover is detachable. As a result, battery replacement is simple and swift and doesn’t require taking the optic off.


Due to its simple battery placement, Vortex Venom wins in the end.

6. Windage and elevation

Venom: The turrets on the Venom move swiftly and smoothly, which simplifies sighting. I was delighted with how rapidly I could zero. I fired 20 rounds to zero at 25 yards during my test execution. The precision and consistency of this red dot astounded me. The zero was still holding after one hundred rounds. That is the best I can hope for! It brought to mind the Holosun 507C that I never had to re-zero while practicing shooting.

Maximum elevation adjustment for Venom: 130 MOA

Maximum windage adjustment for Venom: 100 MOA

Viper: The Viper has locking turrets, which is the only notable difference. You must first unlock the turrets, adjust, and then lock them again to make adjustments. This convenient little detail protects against unintentional adjustments.

Maximum Elevation Adjustment for Vipers: 120 MOA

Maximum Windage Adjustment for Vipers: 120 MOA

When comparing Venom and Viper, Venom lacks lockout functionality. Still, I encountered trouble with the Viper’s turrets trying to unlock the adjustments as the back sights obstructed them. I eventually had to take my rear sights off to figure out how to turn the screws from an angle. I had high hopes for the turrets of the Viper, but they fell short. I believe I wouldn’t have needed to remove my rear sights if the turret locks were placed on the top or side of the optic. Furthermore, both optics have 1 MOA of adjustment per keystroke, which is more than sufficient for a small red dot. 


Vortex Venom wins the battle.

7. Mounting

Venom: Although the Venom comes with a simple Picatinny mount, I suggest mounting this optic to the “TandemKross Shadow Rail mount.” Due to the “TandemKross Picatinny” rail’s ability to allow for a more accurate position of this red dot, it ended up being a great pairing.

Viper: I advise purchasing the “AT3 Tactical” Pro-Mount Red Dot Riser mount instead of the generic Weaver and Picatinny mount with the Viper. This mount will increase the Viper’s low-profile design to change the game and take advantage of the unlimited eye relief.

This optic will function properly with the included mount to benefit from the Viper’s low profile and increase its adaptability.


Vortex Venom wins the battle.

8. Price

Venom: For more expensive red dot sights, Venom’s price isn’t too bad. However, it is also not overpriced, making it a good option for those on a tight budget.

Viper: The vortex viper cost, making it slightly more costly than the vortex venom.

Although it’s not by much, the vortex venom and Viper are roughly at the same value.


Vortex Venom wins the battle because it is less expensive than Vortex Viper.

9. Weapon choice vs. shooting distance

Venom: Generally speaking, the Viper and Venom are better suited for pistols and rifles, respectively, because the two kinds of weapons are typically used at different ranges. The Venom might be a good choice if you shoot highly competitively with a handgun and are shooting from 50 yards and beyond.

Viper: The Viper might be a superior option, however, if you only use your rifle for home defense or for situations that typically take place within 25 yards.

In this case, it is critical to balance precision with flash detection and ranging, but individual preference also matters. Your best course of action, if both precision and quick target acquisition matter to you, is to choose the one that corresponds to the range at which you’ll be shooting, and then rehearse. Your goal will become more specific as you rehearse, and either one can be used to accomplish this successfully.


As I mentioned above, the weapons and shooting distance determine who wins.

Each also includes useful add-ons and a warranty that is unconditional for life. Both provide a distinct, large field of view. Both provide a distinct, large field of view. Which one is best for you will depend on its dimensions, architecture, and most crucially, its capabilities. Despite the fact that a vortex viper is a great option for pistols and the vortex venom is a good choice for rifles, we believe the vortex venom is a better overall choice. It should be clear by now that I would choose and recommend you to avoid Viper.


What is the difference between 3 and 6 MOA?
