EOTech vs Trijicon (2023 Comparison Guide)

eotech vs trijicon
Alfred Mendoza

There’s a ton of sights in the market, and it can be dizzying to think which one is the right choice. We pitted two of the most popular and state-of-the-art sights against each other: Trijicon vs EOTech. Let’s see which one has a better edge as per your needs.

Trijicon and EOTech are equally reputable sights with unparalleled performance. However, they differ in more ways than one. The former is a reflex sight while the latter is a holographic sight. Trijicon is made from 7075-T6 aluminum, while EOTech is constructed from aerospace-grade aluminum. Trijicon’s glass has a bluish or greenish tint, unlike EOTech, which is impressively clearer.

The EOTech holographic sight features 1 MOA dot size reticle, and it’s parallax-free at about 25-40 yards. By contrast, the Trijicon reflex sight uses a 2 MOA dot reticle and can have minimal parallax shift at 25 yards.

EoTech is powered by a CR123A battery, which can last up to 600 hours of continuous use at setting 12. Trijicon runs a CR2032 battery that can last up to 50,000 hours of continuous use at day-setting 3. TheTrijicon apparently has a longer battery life than EOTech

How Are They Similar?

Both sights were designed for the same purposes: rapid target acquisition, accurate shooting, and close-quarters holdover. They are made from exceptionally durable materials and constructed based on military standards. The optics are water-resistant, shockproof, and fog-proof. Their optical surfaces are anti-glare, which provide a crisp, clear image of your target.

These two sights can withstand aggressive recoil from a high-powered rifle without undermining shooting accuracy. You can also attach a magnifier in front of them. Both are compact models that don’t take up much space in your firearm’s rails. 

  • Extremely durable
  • Good battery life
  • Accurate

Key Features


Both sights aren’t budget-friendly. However, you are paying for the quality and performance that you can’t get from their cheaper alternatives. EOTech has a much steeper price than Trijicon MRO/ACOG. Nevertheless, know that either sight is way less expensive than Aimpoint.

Weight & Size

If you need an ultra-compact and lightweight sight, either of these products is a good choice as they take up little space in your rifle.If you mount a magnifier or any accessory, these optics won’t weigh you down.

EOTech is slightly heavier and bigger. It weighs 11.2 oz. It’s 3.8’’ long, 2.3’’ wide, and 2.9’’ high. Trijicon MRO weighs around 4-5 oz with a mount. It’s 2.6’’ long, 1.7’’ wide, and 2.0’’ high.

Battery Life

Trijicon MRO/ACOG can last up to 5 years of continued use at day setting 3. It’s powered by CR2032 battery, which is quite accessible everywhere. EOTech runs by CR123A that can last between 600 to 1,000 hours. These sights are often used in combat shooting and are quite popular in the military since you don’t need to turn them on every time you use them.

Image Quality

EOTech XPS3 image quality

Both sights are made from high-quality glass lenses that can deliver a pretty clear image of your aim. EOTech has a crystal clear lens without any bluish tint, which means there’s less image distortion. By contrast, Trijicon MRO/ACOG has a bluish tint, but some think it would provide greater contrast.

If you have astigmatism, it’s better to get a holographic sight for comfortable and clearer viewing of the aim. In a red dot sight like Trijicon MRO/ACOG, the point of impact may look blurred or mishmashed.

Brightness Control

Trijicon MRO/ACOG features an ambidextrous brightness control that is easily adjustable. This optic has 8 brightness settings, including 2 night-vision compatible settings. Meanwhile, EOTech has 20 daylight brightness settings and10 dark lighting settings. With this optic on your rifle, you can stare even at the sun and still see the reticle.

Focus & Clarity

EOTech features 1 MOA red dot along with a 65 MOA optic reticle ring for range estimation. Your dot will cover 1’’ circle at 100 yards, 2’’ at 200 yards, and so on. It’s well-suited if you want to enhance the precision of your long shots. Trijicon MRO uses 2 MOA dot reticle, which means it will cover a 2’’ circle at 100 yards, 4’’ at 200 yards, and so on. This optic is better for closer or moving targets.

Further Reading:

Zoom Range

It’s important to know what optic best fits your needs. Will you be firing at closer or longer distances? Moving or stationary targets? The two optics in this review don’t magnify the field of view. But you can mount a magnifier if you like to zoom in your aim.

For long-range expeditions, check out this Bushnell Engage review.

Eye Relief

One way to test your optic’s reliability is to determine the comfortable distance between your eyes and the eyepiece.

The two optics offer unlimited eye relief. You can shoot using your rifle with both eyes open while maintaining situational awareness.

You may not need to mount a magnifier if you’re aiming at a closer distance.

Field of View (FOV)

If you want to get a maximum FOV of your target, then opt for the one with lower magnification. If you like to hunt or shoot enemies at long distances, a higher magnification would be better. EOTech and Trijicon MRO/ACOG don’t magnify the FOV; thus, your target will be the same with normal vision.

The good thing about 1x magnification is that it puts the target and sight on the same plane. Hence, your shots will be accurate. Check here for an in-depth discussion on magnification.

Trijicon MRO Pros & Cons



EOTech XPS3 Pros & Cons



Trijicon or EOTech? We Recommend…

Between Trijicon vs EOTech, we recommend EOTech XPS3 because it’s a holographic sight which delivers more pinpoint accuracy and faster acquisition of targets. It has a clearer lens without any tint. The reticle size is well-suited for both close-range and long-range engagements as well as for moving targets. Even though the battery life is shorter as compared to others, this optic offers unlimited eye relief and maximum FOV.
