Overall – EOTech XPS2 – 0

EOTech is a holographic sight with a 1 MOA ballistic dot and 68 MOA circle. This holographic sight is compact and very versatile. This can be a great option for people who like to have more rail space to mount other gadgets like a magnifier. 

The compact size of this holographic sight is due to its transverse battery adjustment. EOTech XPS2 – 0 uses single 123 batteries. The XPS2 sights do not have the night vision setting, but you can easily find those in other ranges of the same product. 

The battery is correctly sealed with an O-ring to provide utmost protection. The battery cap and latch are eliminated from the gadget to make it clean looking and light. 

EOTech holographic sight uses more complex electronics than the traditional reflex red dot sights. You will learn more about the pros and cons of both types of sights further in the article. 

Noteworthy Features 

  • Compact design 
  • Lightweight 

Now, each feature and section will be compared for both the dot sights to give you a better understanding of each of the products. You can expect a detailed explanation of important features like magnification, adjustments, structure, compatibility, and finally, the conclusion. 

Optics Comparison 

One striking feature of Holosun is that it possesses Multiple reticle systems which are extremely convenient for all the users. An individual can set the reticle adjustment according to one’s convenience and liking. 

Holosun has a 65 MOA circle with a 2 MOA dot. With Multiple reticle systems, you can choose to have multiple settings as per your liking. 

The settings can be 

  • Only 65 MOA circle
  • Only 2 MOA dot 
  • Both 2 MOA dot encircled in 65 MOA dot. 

This allows the user to have multiple options while shooting. The 2 MOA dot with 65 MOA circle is a nice combination for crisp target acquisition. The settings can be easily changed by pressing down the minus button used to set the brightness level. 

Coming to EOTech, Eotech is a holographic sight that does not produce a reflection on the front lens. As said earlier, the holographic sight employs more complex construction. Hence, it is different from conventional reflex sight. 

This holographic sight produces a grainy image which is preferred by many people. There is a slight difference between the reticle and reticle ring in the EOTech. EOTech has the 68 MOA and 1 MOA dot. 

Eotech has a slightly larger ring and a slightly smaller reticle dot. 


The magnification of Holosun and EOTech are pretty much the same. Both these sights give 1x magnification for necessary magnification. Holosun gives a crisp and clear image of the target without imparting a green or orange tint. EOTech also gives a clear target spotting at near and far distances. 

1x magnification is apt for both the gadgets as these are not specifically meant for major magnification. Reflex sights and Holographic sights both come under that non-magnifying section of the gun-sight. 


Adjustments are required for optimizing the better image production and usage of the sight. These adjustments help in achieving better image results. Hence, these are quite important. 

Holosun has 12 brightness settings which allow you to set the brightness level in correspondence with the surrounding light conditions. 

These 12 settings have 10 daylight settings and 2-night vision settings. Night vision settings are a bonus that helps a lot during night expeditions. 

On the other hand, EOTech also has 12 brightness settings but it does not have a night vision setting. However, you can find night vision settings in XPS3 variants. 

Battery – 

Battery comparison is also a very crucial aspect to look into while buying a reflex sight or holographic sight. 

Holosun has CR2032 batteries which are functional up to 50,000 hours at the brightness level of 6. Holosun has some great battery saving features that make it the best option on the market in terms of battery usage. 

Holosun has some amazing features added to the reflex sight in this battery segment. 

It has the Shake Awake feature which automatically switches it off when there is no movement. This ensures that there is no unnecessary battery drainage. As soon as it senses any motion, it turns back on. This feature eliminates the unwanted toggling on and off button. 

Another feature that is present on the Holosun is the Solar Failsafe feature. This means that that is fail-safe because it can be operated with solar power in case of battery failure. 

Collectively, these features will help in saving maximum battery and extending the battery life. 

EOTech has a CR123A battery. It is operated with a single battery that is transversely fitted. EOTech does not have any additional extra features like the Holosun, which is quite a bummer. 


Holosun is quite durable and tough because of its sight housing structure. It is made from a high-grade titanium hood that gives it the needed ruggedness and durability. 

The settings and knobs are flushed into the sight housing, which makes the knobs snap-proof. These knobs can be turned easily by a screw-driver. Every rotation corresponds to a 0.5 MOA adjustment. 

Eotech XPS2-0 has 2 aluminum hoods that give it the needed durability and toughness. Windage and elevation knobs are flushed into the sight housing. Similar to Holosun, the windage and elevation c=knobs can be adjusted with a screwdriver. 

Other features of Holosun include water-proof nature up to 1 foot in the water.  Hence, this concludes that it can resist any adverse conditions that can cause harm by water, like rain, snow, and storms. 

For EOTech, It is also water-proof but up to 10 foot in the water, which is remarkably good than the Holosun HS510C


When it comes to weight, Holosun weighs almost half in comparison to the EOTech. Holosun weighs 4.94 ounces whereas EOTech weighs 8 ounces. 

Dimensions of Holosun – 3.3″x1.68″x1.78″

Dimensions of EOTech – 3.5″x 2″x 2.4″

This clearly shows that Holosun is more compact and lightweight in comparison to EOTech XPS2 – 0 


In terms of compatibility and mounting, Holosun comes with an extra accessory that is a mounting tray or battery tray. The need to detach this tray will occur in case of battery replacement. 

The mount is easy and quick to attach. It also gives the convenience of a battery tray compartment. 

EOTech does not come with any extra mounting accessories. It can easily be mounted on Picatinny rail. 

Now that we have discussed all the important features and aspects of both the sights, let’s reach a final verdict/conclusion. 


  • Holosun comes with a multiple reticle system that gives the user the convenience of choosing any suitable reticle option. It imparts versatility to the gadget. 
  • The lens of Holosun gives a clear crisp picture whereas, for the EOTech holographic sight, it is a bit grainy image.
  • There is a slight difference in the reticle size and ring in both the sights. Holosun has a 2 MOA red reticle with a 65 MOA ring. EOTECH has 1 MOA reticle with 68 MOA circle.
  • Holosun has 12 brightness settings which include 2-night vision settings. EOTech also has 12 brightness settings but it lacks the night vision settings. 
  • Holosun is water-proof up to 1 foot in water whereas EOTech is waterproof up to 10 feet. EOTech has also passed a military-grade drop test. 
  • Holosun has two amazing battery saving features that are ‘Solar FailSafe’ and ‘ShakeAwake’. These two features help in maximum battery retention. 
  • Holosun is more compact and light-weight than EOTech. Holosun wins on the weight aspect because of its lightweight and compact size. 
  • Holosun is cheaper than EOTech and has more functional features than EOTech. 

These points will provide you a better insight into the working and features of each of the products. You can opt to buy any of these gadgets, which suit your requirements.
