Eotech’s Holographic Weapon Sights (HWS) include some of the world’s fastest sighting systems. They’re used by the military’s special-ops and law-enforcement. Only the shooter can view the holographic reticle and non-reflective window, which makes them different from red-dot sights. They contain no metal-coated or mirrored surfaces to reveal your location.

The 512 is more popular than the XPS2 and is widely used as a sight for night vision. It’s designed for shooting in the close to mid-range. Meanwhile, the XPS2 is designed for the same distances. However, there are still some significant differences between the two products.

Applications/Ease of Use

The XPS2 and 512 are both easy to use and mount. They also can be used with a MIL-STD-1913 or 1-in. Weaver rail. Both of the sights have been used by military personnel and law-enforcement officers, so they’ve proven their value in the field.

Let’s get to the nitty-gritty of these optics. The XPS2 and 512 are relatively basic units. They both use the company’s in-house square-shaped design. They’re also both designed for rifles and shotguns, as well as close-range shooting.

Both of these Eotech sights also feature a dynamic reticle that sets them apart from standard red dot optics. The XPS2 and 512 both include the base option of a big circle & mini dot. This system is excellent for close-range shooting and up to 200 yards. They both could be used for applications like hunting, competition, and home defense.

Setting System

Another of the main features they both share is a setting system that’s memory-based.  A basic button-push provides easy operation of this feature. After setting the optic to a particular setting, you can then switch off the optic. Then when you switch the optic back on the setting automatically returns to that figure.


One issue that’s often addressed when comparing the two items is recoil. In particular, the battery compartment of the XPS2 allegedly handles recoil better than the 512’s AA battery compartment.

There have also been reports the 512’s battery cap is less effective at handling recoil than the XPS2, and the batteries’ positioning could damage the compartment.

In fact, the XPS2’ battery cap is indeed smaller/more secure, and the AA battery is mounted sideways. This helps to keep it secure after being mounted and prevents it from moving around in the compartment. In part, these issues explain the XPS2’ higher price tag.

However, the 512 is still regarded as a quality sight and is extremely popular, and many owners haven’t experienced these recoil issues.

The 512’s popularity is evident in it usually the first thing that comes to mind when you mention its manufacturer Eotech.  It’s a highly-respected optic and was released quite a while ago.

Differences between XPS2 & 512


The XPS2 is lighter due to the slimmer design. It’s also much shorter so the owner can easily mount other accessories.

Reticle Pattern

It’s worth noting the 512 is only available in one reticle pattern. Meanwhile, the XPS2 is actually available in multiple reticle patterns. This is a major difference and something worth considering in terms of the product’s flexibility and applications.

LBC Compatibility

Eotech introduced its laser battery cap (LBC) series several years ago in 2014. They include the LBC and LBC2. The XPS2 isn’t compatible with LBCs. So, if this is a must-have feature, then you should go with the 512. You can even buy a 512/LBC bundle.

Battery Life

Let’s start with the batteries themselves. The UXPS2 uses a single battery that’s powerful yet expensive. The 512’s lithium battery life is up to 1,000 hrs. while the XPS2 has a battery life of up to 600 hours.

The significant difference is based on the XPS2 being a shorter optic. However, this also results in the drawback of a shorter battery life. This battery is also tougher to find so it might be an issue. If you buy rechargeable lithium batteries, you can boost their value.


The XPS2 and 512 are both in the under-$100 price range, so they’re good options if you want to pick a budget sight. That said, the XPS2 has a higher price tag mainly due to the battery type and related issues.

Which one is right for you? If you plan on adding an accessory like a magnifier, then the XPS2 is a good option for freeing up space. Meanwhile, if you probably won’t take that step, then the 512 is generally a better option.


What’s the bottom line? In this Eotech xps2 vs 512 comparison review, we’ve discussed the features, pros, and cons of both units. Who did it better? The two units have very similar specs and features, so it basically boils down to picking the 512’s stellar reputation or the XPS2’s accessory-friendly design. Choose wisely!
