One thing is for sure: Those looking at the best EOTechs for AR 15 use will surely only be buying one at a time!

These highly effective holographic weapon sights certainly don’t come cheaply. Having said that, what they do offer is a whole new insight to your shooting experience.

This means that the selection of this superb, high-end accessory needs to be carefully considered and be exactly the right fit for you.

So, let’s start off with some background information…

What’s the real difference between regular scopes and holographic sights?

Simply put, holographic sights take your viewing and accuracy abilities to a whole new level. The best quality EOTechs are far more accurate than the best regular scopes. They afford a better view, real accuracy of target sighting, and a clear focus of everything you are viewing.

A very different reticle – here’s why…

Reflector sights use what is termed as a reflected reticle system. EOTech holographic sights do not. Their reticle is recorded using three-dimensional space onto holographic film. This is part of an optical viewing window.

Using collimated light, the reticle offers an aim-point which can move with your eye position. Furthermore, because a laser is used as the light source, it means the aiming reticle can be a minuscule dot.

Example: Those with 20/20 vision will see the dot appearing around 1 MoA.

Another eyes wide open benefit!

The superior design of this reticle makes it very easy to shoot with both eyes open!

EOTech sights also compensate for any change in the laser wavelength thanks to holography grating. This means light is dispersed in the opposite direction. This results in a stable reticle regardless of temperature changes.

We’ll get into considerations of whether this type of sight is right for you at the end of the review, so now we’ll move onto the products themselves…

Top 5 Best EOTechs for AR 15 Reviews

  1. EOTECH 512 Holographic Weapon Sight

Anyone looking for their first holographic weapon sight would be wise to take a long look at this one. It surely ranks in the best first purchase EOTechs for AR 15 rifles. And this is borne out by the fact that it is the most popular in the company’s excellent range. And it is also the cheapest!

It is a durable, highly reliable, and versatile sight and provides super-fast target acquisition. Made from a long-lasting aluminum, it offers standard features that are easy to use: Exactly what you need if you are new to this type of equipment.

Windage adjustments offer a click value equal to ½-inch at 100 yards.

Ease of mounting…

It will mount directly onto a 1-inch Weaver or MIL-STD 1913 rail meaning no tools are required for such attachment. And power is provided by a choice of batteries; 2 AA’s, rechargeable batteries, lithium or alkaline.

Runtime indications

This scope can run between 600 continuous hours if alkaline batteries are used. Up to 1,000 continuous hours if lithium batteries are installed. Both assumptions are based on running the sight at level 12 brightness setting at room temperature.

In terms of brightness settings, there are 20 in total, and the incredible picture clarity is sure to impress. It is also water-resistant and submersible to a depth of 10 ft.

You have the choice of 2 colors: Black or Camo. Weight-wise it is not the lightest, coming in at 11.5 oz and it should be noted that there is no night vision capability.

EOTECH 512 Holographic Weapon Sighta
Our rating:4.6 out of 5 stars (4.6 / 5)

  • 20 brightness levels.
  • Accepts a variety of different battery types.
  • Lowest cost.
  • Excellent entry-level scope.
  • No night vision capability.
  • On the heavy side in this category.
  1. EOTECH 552 Holographic Weapon Sight

Moving up a notch, we come to the EOTech 552 model. You will find this is very similar to the 512 model just reviewed.

But there are a few extras…

The main difference is that it is night vision compatible. This is obviously important for those night hunters out there, but obviously not such an important feature if you are a daytime type.

It also mounts as standard (and without tools) on the 1-inch Weaver and MIL-STD 1913 Rails and is water-resistant up to 33 foot. Battery life equates to that of the 512 model, and the controls are also similar.

The simplicity of use is what will please many, particularly those who are new to holographic scopes.

Here’s an example of that…

There are two buttons on the rear – One to switch it on and off, the other to adjust brightness. There is then a 3rd button to activate night vision mode, which in turn offers another ten settings.

One other option to consider are EOTech’s Laser Battery Caps. These work as drop-in replacements to the sight’s battery compartment cover. They come with either red and IR lasers or just a red laser built-in.

EOTECH 552 Holographic Weapon Sight
Our rating:3.8 out of 5 stars (3.8 / 5)

  • Night vision capable.
  • 20 light settings + 10 night vision settings.
  • Water-resistant up to 33 ft
  • Only for those who need night vision capabilities.
  • Same weight as the 512 model, i.e., heavy!
  1. EOTECH EXPS2 Holographic Weapon Sight

This has to be classed in the best, mid-priced EOTechs for AR 15 use. And it features a sturdy aluminum housing that will protect it against shock and the elements. It is water-resistant up to 10 ft and weighs in at 11.2 ounces.

For power purposes, it uses one x 123 Lithium battery. This will run for up to 600 hours continuously (based on level 12 brightness setting). Twenty levels of brightness are again yours with two small buttons on the side of this sight for adding a magnifier.

Minimal rifle space taken up…

The sight mounts without tools on the 1-inch Weaver and MIL-STD 1913 Rails and takes up just two ¾-inches of rail space. This mount also offers a quick detach lever for sight locking and release.

If a compact sight without night vision is what you are after then, this certainly rates as a strong consideration.

EOTECH EXPS2 Holographic Weapon Sight
Our rating:3.7 out of 5 stars (3.7 / 5)

  • Minimal rail space taken up.
  • Quick-release lever feature.
  • Single battery.
  • Battery life is less than other reviewed models.
  • Does not offer night vision capability.
  1. EOTECH EXPS3 Holographic Weapon Sight

Another notch up on the best EOTechs for AR 15 use is the EXPS3 model.

Similar but with added features…

The EXPS3 holographic weapon sight is similar to its sister EXPS2-0 model just reviewed but offers even more.

This sight can truly be put forward as use for true ‘two eyes open’ shooting. This capability certainly offers fast target acquisition. You also have a 7mm raised base affording iron sight access in a unit weighing in at 11.2 ounces.

The other big plus…

It is night vision capable. As such, you can choose between 30 brightness levels. 20 for day time plus 10 for after dark.

Battery-wise it takes a single 123 lithium battery. On continuous use at standard brightness (level setting 12), you will get up to 600 hours of continuous use.

As with other EOTech sight designs, this one fits seamlessly onto AR 15 rails (1-inch Weaver or MIL-STD 1913). The easy-adjust quick detach lever is certainly a useful feature.

EOTECH EXPS3 Holographic Weapon Sight
Our rating:4.1 out of 5 stars (4.1 / 5)

  • Works with all 1-3 Gen. Night Vision devices.
  • 7mm raised base – Iron sights can be used.
  • Technically you have unlimited eye relief.
  • In the higher price bracket.
  1. EOTECH HHS I Holographic Hybrid Sight

Our final best-in-class EOTechs for AR 15 sight use is the Holographic Hybrid Sight (HHS). This model does offer night vision capabilities.

We’ll start with a unique feature…

Best to get off on the right foot! With that in mind, here’s something to consider:

The unique ability to switch to side mount with this sight allows quick disengagement of the attached magnifier giving you a close-range scope in no time at all.

What does this mean?

If you have a quick focus change, it is possible to respond in rapid time. This means that you will still have the chance of an accurate shot.

The scope is powered by a lithium 123 battery and at standard (setting 12) will give up to 600 hours of use.

This high-quality sight offers 4 dots as opposed to the standard 1 dot on other models.

But what does this mean to you?

It allows you to focus in for far greater accuracy. The included magnifier is considered as one of the clearest available.

While it is double the weight of the other reviewed scopes (22.4 oz), you need to remember it is packing a lot of punch.

EOTECH HHS I Holographic Hybrid Sight
Our rating:4.2 out of 5 stars (4.2 / 5)

  • Higher accuracy thanks to 4 dots.
  • Highly effective for close quarter situations.
  • If regularly shooting over 300 yards, there are better alternatives.
  • On the heavy side for some.

Best EOTechs for AR 15 Buyers Guide

 Important note – Warranty 

Rather than be repetitive in our reviews, we felt it best to mention an all-encompassing warranty.

All scopes reviewed come with the EOTECH HWS Prestige Warranty – This means they come with a 10-year limited warranty.

 Purchase considerations you need to take into account: 

  • Yes, holographic sights will help take your shooting experience to the next level.
  • No, they are not for everyone!

The cost of securing the best priced EOTechs sight for AR 15 use is not to be scoffed at. This means it is important to take into account the following considerations before committing.

 Amount of use 

Are you an occasional shooter or finding less and less time to spend with your AR 15? If so, this amount of use may very well not require the purchase and use of an EOTech holographic sight.

On the other hand, those in regular tactical situations, active competition shooters and keen hunters will benefit. A major advantage here comes from clearer, more accurate images of chosen targets.

Another important ‘use’ consideration…

Think about the need for night vision capability. Do you really need this? The reason for mentioning it is that holographic scopes without a night vision feature will cost you quite a bit less.

 Field of vision 

In many ways, this consideration will have a bearing on our first point in terms of use.

How’s the view?

This is something you need to ask yourself in terms of importance. Competition shooters and avid hunters will need clarity and a sound field of vision. Holographic sights offer this. Occasional users may not be so pressed for such a feature.

 Size of the sight 

The size of the sight and its weight can be a differentiator. While some of the larger scopes will suit, they can add unwanted weight.

Many of the smaller scopes are lighter in weight but could be beyond price acceptability. This means there could be a potential trade-off to consider.


Last but certainly not least. All sensible shooters will weigh up equipment costs before committing. This is a particular requirement when it comes to investment in the best cost acceptable EOTechs sight for AR 15 use.

EOTechs sights are not cheap. But, with regular use and the 10-year limited warranty, you will certainly get value from such an investment.

But not so if you purchase one and its main occupation is to gather dust!

 Careful consideration will pay dividends 

Once you have taken the above into careful consideration, you will be able to make a sensible, informed decision. If the benefits of owning the Best EOTechs for AR 15 use outweigh any negatives, this is what you will get a sight that really can take your shooting enjoyment to the next level.

So what are the Best EOTechs for AR 15?

There is no argument that EOTechs are the industry leaders in holographic sights. This means that selecting any of the above sights will assure you get quality, durability, improved accuracy and crisp, clear visuals.

But, in terms of hitting a best mid-price AR-15 EOTech sight, we have to plump for the…

EOTech EXPS2 Holographic weapon sight

It is one of the lightest, smallest options available. It is also geared towards giving both hunters and competition shooters satisfaction.

With 20 levels of brightness, most will find this sufficient. The only caveat here is for night owls; they would be wise to go for the night vision features offered by the EXPS3 model.
