Holosun 510C VS Eotech XPS2 [Which One Is Better?]

The Holosun and EOTech are the popular manufacturers of red dot sights. So, it’s very normal to get confused while choosing a sight from these brands. Especially, when the sights like Holosun 510c and EOTECH XPS2 have the same sort of quality and functionality, the decision gets more difficult.

Hence, we have brought you a comparative discussion on these sights so that you can make a better decision while choosing a sight for your firearm. But we would suggest when you’re going through their comparisons, keep your shooting needs in consideration. This way it will be easier to find out which sight will be perfect for you. So, let’s start!

Holosun 510C

Key Features

  • Lightweight and compact.
  • Adjustable brightness.
  • Quick release mounting system.
  • Night vision device compatible.

When it comes to red dot sights, Holosun is currently one of the leading brands. Their HS510C would be a top priority for anyone looking for a red dot for their rifles. While it’s not the most expensive option in the world, it does wonder in the price bracket it’s competing.

The optic is made out of high-quality aluminum. It’s the same type of aluminum you see in high-end scopes. The entire housing is shockproof, fogproof, and waterproof. You can submerge the optic if you wish to. While I don’t necessarily recommend you do that, I certainly do recommend using it in cold weather.

An illuminated reticle and adjustable brightness make it an appealing choice for night vision endeavors as well. While it’s not the ideal choice for hunting short to medium range, you can definitely use this on a bolt-action for plinking.

Eotech XPS2

Key Features

  • Extremely durable.
  • Will work with a broken lens.
  • Lightweight and compact.
  • Suitable for entire day usage.
  • Extremely bright with maximum intensity.

When looking for an ideal compact holographic sight, Eotech will come on top. Their optics are used by civilians and law enforcement services. Their sights are quite expensive and the price tag makes sense. The care Eotech puts through behind one of these optics makes a lot of difference. Thanks to that, no clone has come close to the original.

The holographic crosshair on this optic is illuminated. You will find plenty of brightness settings to increase or decrease the intensity depending on your environmental lights.

The housing is made out of aluminum. It is also submersible if you wish to do such. The optic also comes with a mounting system that you can easily remove if you want to take off the optic and install something else. Overall, it’s one of the best budget choices if you are looking for a holographic sight for your firearm.

Holosun 510C/ EOTECH XPS2 – Differences

Even though both of the sights are good in quality, they have technical differences that can impact your shooting experience. So, we will be discussing the sights in the following terms:

  • The sights are constructed with different materials, hence, we will be looking at how they can influence the durability and performance of the sights.
  • Since the MOA circle of the sights is not the same, it may impact your target acquisition.
  • Both of them have different battery types with different battery life hours which work as one of the deciding factors for an economic purchase.
  • The brightness adjustment of the optics is not similar, so, the target visibility gets affected due to this difference.
  • The products are offered with various sorts of accessories.
  • Lastly, the sights have two different types of warranty policy.

Discussion On The Sights

While the Holosun 510c is an open reflex sight, the EOTech XPS2 is a Holographic sight. And they both work great when it comes to close target acquisition. However, depending on the shooting purposes, the preferences for the sights vary. Therefore, this discussion will show which sight you should choose according to your shooting needs (civilian or tactical).


The construction material can create a big difference in the sight’s quality. Though these two sights are crafted with high quality materials, they still have a few differences in their construction.

Holosun 510c: This model has Aluminum made housing and a Titanium hood to protect the sight lens. This makes the sight extremely durable against heavy impacts of recoils. Plus, the windage and elevation turrets are recessed into the sight housing. As a result, their adjustments don’t get changed in bumpy or rough situations.

With the 0.5 per click adjustment system, you can easily adjust the windage and elevation. To make the windage and elevation adjustments, you can use either a screwdriver or a rim of a cartridge.

In addition, the sight is submersible up to 3ft. or 1 meter. It means it also has a strong resistance against water or foggy environments.

EOTECH XPS2: On the other hand, this model has Aluminum construction in both housing and hood. Plus, it has similar windage and elevation turret placements. Its adjustment system is similar to the Holosun 510c.

However, they have huge differences in their submersion level and weight. While the EOTech XPS2 has a better water difference, the Holosun 510c has less weight than the former model. The EOTECH XPS2 is submersible up to 10ft. (3m) which is much higher than the 510c (3ft. Or 1m). But when the 510c weighs around 4.94 oz, the XPS2 weighs 9.0 oz.

However, let’s not forget, the 510c is an open sight which means the mud and debris will be more stuck to it than the XPS2. Moreover, the XPS2 model has gone through the military drop tests and got approved as a military grade sight. Hence, in terms of sight reliability, the EOTECH XPS2 weighs over than the Holosun 510c.


The reticle systems of the sights are equally good for fast target acquisition. But they have different MOA circle sizes which may matter to some of you.

Holosun 510c: Honestly one of the cool features of this model is its Multi Reticle System (MRS) where you get 3 reticle options to aim for the targets, such as:

  • A 2 MOA dot
  • A 2 MOA dot with a 65 MOA ring around it (Circle Dot Reticle)
  • A 65 MOA ring (no dot in the center)

The 2 MOA dot is always best for target acquisition from different shooting ranges. But a 65 MOA circle is what mainly enables you to aim for the targets as fast as possible. You can easily switch the reticle types by using the “-” button of the brightness adjustment. Moreover, there is another version of this which comes with a green reticle color.

EOTECH XPS2: The XPS2 has a series of holographic sights with different reticle options. This series has total 3 reticle types, such as:

  • 1 MOA dot reticle
  • 1 MOA dot with a 68 MOA ring around it (Circle Dot Reticle)
  • (2) 1 MOA dot with a 68 MOA ring around it (Circle Dot Reticle)

Since the MOA circle of this model is a bit larger than the 510c model, some shooters may prefer it more than the 510c model. However, there is a big BUT here! While the 510c offers you all these three reticle systems at a time, with the XPS2 model you need to purchase different versions of it to use different sorts of reticles.

Hence, even though XPS2 has a larger MOA circle, buying the 510c would be more beneficial for you. Because, with this sight, you will also be able to make quick aim on the targets and will have 3 reticle types in one single model.


Without a high capacity battery, a sight will never be able to support you for a long time. Hence, whenever you purchase a sight, ensure it is provided with a good quality battery.

Holosun 510c: This sight is offered with a high capacity CR2032 battery. It will help you to use the sight for up to 50,000 hours of battery life. The best part of this model is its features like Solar Power Failsafe Technology and Shake Awake Technology.

The solar panel system of the optic never lets it die in the field. Because as soon as the battery fails, this solar panel technology powers up the sight to function. On the other hand, the Shake Awake Technology works to prolong the battery life by shutting it off when it is not in motion. It can also instantly power it back when it senses movements of the sight.

EOTECH XPS2: The sight is offered with a CR123 battery which allows you to use the sight for up to 1000 hours. So, you can clearly see that the battery life of this sight is a lot lower than the 510c model. However, this is like 510c, has the automatic shutdown feature, after 4 or 8 hours of inactivity the optic can be automatically shut off.

But it can’t automatically turn itself on. You have to power it back manually. Plus, the optic can let you know if the battery is running low. If you see the reticle flash for a moment when you first turn it on, it’s a sign that the battery power is low.

All in all, the power backup is really stronger in the 510c than the XPS2.

Brightness Adjustment

The sight you’re choosing should allow you to make proper brightness adjustments. otherwise, you won’t be able to have a clear view of the targets to make accurate shots of them.

Holosun 510c: There are 12 brightness adjustment settings in the Holosun 510c. You will have 10 level settings for daylight time brightness adjustment. Plus, 2 night modes to have target visibility in low light conditions. So, this model is compatible to be used in any lighting conditions.

EOTECH XPS2: Conversely, this model has 20 daylight brightness adjustment systems. Hence, obviously, you’ll get more daylight brightness settings with XPS2. However, this sight doesn’t have night vision compatibility. It means you won’t be able to use it in low light conditions.

But since this has a compact design, it doesn’t take much of the rail space, so you can use night sights along with it. Then again you have to invest a good amount of money to purchase a night sight to have target visibility in low light environments.

Therefore, in terms of the brightness adjustment, the Holosun 510c has better settings than the XPS2. At least, you won’t need to invest extra money to have low light visibility.


The sights are provided with a certain amount of accessories. So, you can also compare that at the given price of the products, what else you are getting with them.

Holosun 510c: Following is the list of the items you will get with this sight:

  • T10 L key
  • Absolute Co-witness QD mount
  • User manual
  • CR2032 battery
  • Lens cloth

The best part of this model is if you own a rifle like AR-15, you don’t have to buy a mount separately. Additionally, it will help you to co-witness with the iron sights as well.

EOTECH XPS2: Below is the list of the accessories that are offered with this sight:

  • Quick-start guide
  • Warranty card
  • CR123 battery
  • Protective case

In addition, the sight has an attached mount which enables you to install it on any 1” Weaver or MIL-STD 1913 rails. Especially, if you have an AR-15 rifle, it will allow you to Absolute Co-witness with the iron sights.

The difference between the sights in this regard is that the 510c model has a QD mount, enabling you to quickly attach or detach the mount from the rifle.


Due to many reasons, we often face technical problems with our sights. So, if the company provides a warranty with the product, it works as an assurance that we’ve got covered with technical support.

Holosun 510c: Holosun offers 5 years of warranty for its optical system. Plus, a 3 year warranty for its illumination and electronics. Since the sight has a sturdy construction, you may not even have to use the warranty card. But the company still has got your back for a good amount of time.

EOTECH XPS2: You will get 10 years of warranty with this optic. The warranty policy covers defects in quality and material wear under regular use. Along with the military drop tests, we believe this warranty policy takes the product’s reliability to another height.

Hence, in the case of the warranty policy, the ball is in the XPS2’s court.


Before you go for the final verdict, let’s quickly take a glimpse of which sight works at its best in the factors we have discussed above.

Well, we believe you got the idea of who wins the battle here. To help you further, let’s inform you, that the Holosun 510 comes at the half price of the XPS2. So, we would say if you use civilian sorts of rifles and most importantly if you’re on a budget, the 510c is your best bet.

However, in case you want to experience something military grade, you can go for the XPS2 sight as well. But keep in mind, for that, you will need to invest a bit more than the 510c sight. So hopefully, now you will be able to make a better decision while picking a sight for your rifle. Good luck!
