EXPS vs XPS

Fellow gun owners, are you looking for a holographic weapon sight (HWS) for your rifle?

Everybody knows that the industry leader for that is EOTech.

But wait — EXPS vs XPS?

What are the differences besides the letter E? How are they different from older models?

They’re quite similar, but they’ve got their key differences too.

We’ve created this review of the new EOTechs just for you.

Overview of the EOTech EXPS Optics

First up: EOTech’s EXPS2 vs EXPS3.

Honestly, they’re almost identical.

EOTech EXPS2

EOTech EXPS2

BUYING OPTIONS:
» Best Price on OpticsPlanet «
» Check Price on Cabelas «
» Check Price on Brownells «

Convenience

The EXPS2’s push-button controls are on its side.

Easy to Use

It’s not only the buttons that make the E model user-friendly.

Another feature — the quick detach lever — makes it easier to use as you won’t be scrambling with an Allen key during use.

Variant Advantage

This EOTech sight is available in an EXPS2-2 version.

This holographic hybrid model promotes a ballistic dual dot reticle. This means you get the holographic sight with a fixed G33 3x magnifier.

If you’re considering getting a magnifier, this would be ideal for you since it will already be bundled in this unit. You won’t need to purchase a separate magnifier.

Clear and Unobstructed View

The EXPS2 sight comes with a 7mm riser. This increases the mounting height giving you a 1/3 co-witness setup with better sight picture and front sight.

Pros
  • User-friendly
  • Lightweight
  • Uses less rail space due to small optic
  • Allows co-witness sighting
  • More affordable price than the EXPS3
Cons
  • No night vision

This way, you have mobility and manipulation if you have other accessories alongside your HWS.

» Check Price on Amazon «

Features:

  • Dimensions: 3.8 x 2.1 x 2.5 inches
  • Weight: 9oz
  • Battery Life: Approximately 1,000 hours
  • Power: 1 CR123
  • Brightness Settings: 20 (daytime)

The XPS3 can withstand water pressure AND extreme temperatures while still working well.

Pros
  • Allows absolute co-witness of the sight and iron sights
  • Anti-glare optic lenses
  • Parallax-free
Cons
  • Requires lens tinting to avoid doubt regarding glare on target
  • Push buttons are at the rear

What Is the Difference Between XPS2 and XPS3?

Again, the main difference between the XPS2 and XPS3 sights is that the latter has night vision devices compatibility.

You will be able to see more clearly with the XPS3 as the dot is still visible.

Additionally, XPS3 is submersible up to 33 feet in depth, while the XPS2 can only be underwater up to 10 feet.

EOTech EXPS vs XPS: The Similarities

1. Performance

Both the EXPS and XPS sights are of high quality AND deliver outstanding performance.

Even if you’re a newbie, don’t fret as these products may actually improve your shooting.

PRO TIP: You can even pair your optic with backup iron sights for enhanced shooting precision.

2. Battery Life

The two models use one CR123 battery (lithium) for power.

This means battery power for about 1,000 hours straight.

3. Brightness

Both sights come with 20 settings for brightness for the red dot, giving you more versatility for various lighting environments.

4. Night Vision

Unfortunately, the XPS2 and EXPS2 sights will not give you this feature.

So if this is a must, go for the EXPS3 or XPS3 instead.

5. Lens

The EXPS and XPS sights both include anti-reflection coating to boost performance despite a frustrating glare.

6. Waterproof and Anti-Fog

The two units are certified waterproof and anti-fog.

However, do note that the EXPS3 and XPS3 can be submerged around three times deeper in depth than the XPS2 and EXPS2.

7. Eye Relief

Both the EXPS and XPS sights provide unlimited eye relief.

This is crucial as it is important for eye relief on sight to be high enough. This will prevent the top of the sight from contacting your eyebrow.

An eye relief’s distance is usually related to the magnification of a particular sight.

NOTE: Eye relief refers to the distance you should hold the shooting eye from the ocular lenses of sight to see the whole image it produces.

8. Warranty

Both sights are covered for 10 years from defects related to materials or workmanship.

EOTech EXPS vs XPS: The Differences

1. Adjustments

The push control buttons are located in different areas for the EXPS and XPS sights.

For the EXPS models, you will find them on the side. While for the XPS, they are on the rear.

The EXPS is advantageous here as the side location gives you more space for mounting accessories on the rifle, like magnifiers.

2. Mounting

A huge difference worth noting is that the E model units come with a quick detach lever, while the XPS series includes mounting screws with a traditional system.

It’s obvious here how a quick detach lever can be such a game-changer and advantageous in several situations.

3. Price

The price of the two sights is under $600.

However, the EXPS is a bit more expensive than the XPS. It’s also larger and heavier.

The price difference is small, though, so if you need a lighter and more compact unit, go for the XPS since it’s also more affordable.

If you’re looking for more affordable EOTech sights, you can consider buying the 512 or 518.

4. Size and Heaviness

The XPS is smaller than the E model units.

Consider this if you see yourself hunting on the daily for hours wherein you’ll be hauling around your rifle and other gear.

5. Reticle Patterns

The EXPS has a selection of five reticle patterns, while the XPS just has two.

6. Co-Witness

The XPS is an absolute co-witness setup. An absolute co-witness means the dot is fully aligned with the iron sights when viewed through the sight’s window.

On the other hand, the EXPS includes a 7mm riser making the viewing window lower 1/3 co-witness.

For close-range shooting, EXPS may be a better option as the iron sights won’t take up space in the window, hence a clearer field of view.
