Eotech XPS2 vs. Holosun HS510C – How do they compare?

Optical Features

The most significant features of a scope lie within its optical characteristics, and its ability to facilitate clear and precise vision for its user. With the Eotech XPS2, users get access to a 22mm objective lens that provides a wide field of view. This lens is made using a mix of clear glass and laminate, resulting in a hardy and highly efficient lens. For guaranteed precision, this scope promises unlimited eye relief and a non-parallax lens.

On the other hand, the Holosun HS510C comes with a wider objective lens, measuring 24mm in diameter. This results in a wider field of view for better precision. The lens is made entirely out of optical glass which has multiple layers, a characteristic that maximizes on light transmission but still keeps glare at a minimal. In addition, it is a parallax free scope that guarantees a good amount of accuracy. Further, it offers unlimited eye relief to make certain that target acquisition is easy no matter where the scope is installed on the rifle.

Since the Holosun HS510C comes with a wider lens and is made entirely of optical glass, it makes a better scope than the Eotech XPS2. 


A scope’s overall performance is put to the test when it is required to operate in different environments with the same precision and delivery. With the Eotech XPS2, you will gain access to up to an impressive 20 brightness adjustment settings which come in handy when you are hunting in different light intensities. When it comes to dot size, it features a 1 MOA red dot which is combined with a 68 MOA ring for great vision. The ring comes in handy where the target is within close range and where it is fast moving. The main down side to this device is that it does not support Night Mode, meaning that all 20 brightness levels are only relevant during the day.

Comparably, the Holosun HS510C comes with fewer brightness adjustment levels, delivering only 12 which is nearly half the number of those on the Eotech XPS2. However, 2 of these settings are compatible with night mode, making it ideal for all day and all night use. For a reticle, it presents a 2 MOA red dot, coupled with a 65 MOA ring which is slightly smaller than the Eotech XPS2’s, but effective none the less. This ring is excellent for close range targets that are fast moving.

The fact that the Holosun HS510C supports Night Vision and is made from optical glass makes it a better scope than the Eotech XPS2.


To be able to work in multiple environments, it is important that a scope be hardy and resistant to damage. This is why the Eotech XPS2 is made from rugged aluminum which makes it quite hardy. This material gives it the capacity to handle heavy impact with ease, and to keep the lens rom shattering even after numerous rounds of recoil. You can use it in heavy rain and even cross rivers with it without compromising on its quality since it is an entirely waterproof tool. Multiple O-rings keep all forms of dust from penetrating through. Most impressively, it is a fog proof device whose visual quality cannot be compromised by the internal formation of fog. When it comes to weight, this device weighs 9.0 oz.

Following suit in similar fashion, the Holosun HS510C also features an incredible build. However, it is made using both aluminum and titanium for extra strength and longevity. Also, it is a waterproof and dustproof tool that has the capacity to resist the formation of internal fog. This ensures that your vision stays clear all through. This tool weighs only 4.94 oz, making it significantly lighter than the Eotech XPS2.

The Holosun HS510C is made using a combination of aluminum and titanium, making it more resistant to impact. It is also a light scope, making it better than the Eotech XPS2.  

Battery Life

Many users, especially hunters, have a large preference for devices that have long battery lives, and this is mainly where the Eotech XPS2 falls short of expectations. It only comes with 1,000hours on its battery, and this is only on its 12th brightness level. Higher levels result in significantly shorter battery life.

The Holosun HS510C impresses in this category since it comes with up to 50,000 hours battery life. In addition, it comes with solar support which acts as backup for daytime use and in case the battery fails. This makes the Holosun HS510C an incredibly efficient scope.

Boasting a 50,000 hour battery life and solar capability, the Holosun HS510C outdoes the Eotech XPS2 by a cosmic margin to become the better scope.
