Eotech 512 vs. Eotech 552 – How do they compare?

Optical Features and Characteristics

A scope’s lens is mostly charged with facilitating clear visuals on your target, and this is why it is imperative that its build be of high quality. For this reason, the Eotech 512 comes with a 22mm objective lens made using a mix of glass and laminate. It features multiple layers that allow for maximum light transmission as well as reduced glare. It comes with a 1 MOA rtcile and a 68 MOA ring that is ideal for use in close-range applications. In addition, it is a non-parallax lens that ensures your vision is accurate to a T. The unlimited eye relief is ideal for keeping your image in sharp focus no matter where the scope is located on the rifle or handgun. For the ultimate vision, it comes with a wide field of view.

Similarly,the Eotech 552 features a glass and laminate lens that has many layers. This characteristic is ideal for facilitating maximum light transfer during use. It also features an anti-glare coat that keeps you from experiencing extreme glare. Just like the Eotech 512, this scope comes with a 1 MOA red dot, but it has a smaller 65 MOA ring. The lens measures 22mm, and it is made to create a wide field of view. Precision during target acquisition is of paramount importance, and this is why this lens is made to be a non-parallax device that also offers unlimited eye relief.

Since the Eotech 512 comes with a slightly larger ring than the Eotech 552, it makes a better riflescope for close range shooting.

Overall Performance

Avid scope users will tell you that they prefer a device that they can use in multiple settings. This is why it is important for a scope to have many brightness adjustment levels. This is why the Eotech 512 comes with up to 20 brightness adjustment levels ideal for various light intensities. For a regular well-lit day, level 12 on the brightness scope is most ideal. On the downside, this scope does not support Night Vision, making it only ideal to use in day time settings.

The Eotech 552 matches up to expectations, delivering up to 20 brightness adjustment levels for daytime use. In addition, it comes with 10 rightness levels that are ideal for use with Night mode. With this feature, it becomes quite easy to use in during the day and even in the cover of night without a problem.

Since the Eotech 552 comes with Night Vision and 10 additional brightness adjustment levels, it outdoes the Eotech 512 where performance is concerned.


To be able to last a good deal of time, a scope has got to have a hard body. For this reason, the Eotech 512 is made using a strong aluminum casing. This feature allows for the scope to be able to handle a good deal of impact as well as multiple rounds of recoil without compromising the integrity of the lens. In addition, it is fitted with multiple O-rings which are ideal for keeping the device from being affected by water, making it entirely water and dust proof. On top of this, it comes with the capacity to resist the internal formation of fog, keeping your lens clear all through.

Similarly, the Eotech 522 features an incredibly strong aluminum body made to withstand huge amounts of impact and recoil with grace. For use in multiple environments, it is made to be water and dust resistant so that it works just as effectively in desert climates as it does in wet and humid environments. For lens clarity, it also keeps from fogging internally, making it ideal for all year use.

Both scopes feature similar constructional features, making them equal in this respect.

Battery Life

For professional use, the best scopes come with long battery lives that could last as long as 5 to 10 years. This is largely where the Eotech 512 and Eotech 552 fall short since they are unable to deliver this kind of longevity.

The Eotech comes with a 2,500 hour battery which is pretty decent. However, it does not last as long as most professionals would prefer.

In the same way, the Eotech 552 also comes with a 2,500 hours battery, a significantly short battery life, especially for people who go into the wild for days on end.

Both batteries have a considerably short battery life, setting them on equal footing.
