Trijicon RMR vs MRO

Optics are necessary when using a firearm, but it’s tricky to pick the right one for your needs. Two of the most popular include the Trijicon RMR and MRO. This article will compare the products to determine which is the winner in the optics category.

Durability, Toughness, and Size

Some of the best items to consider when discussing optics include durability, toughness, and size. These categories influence how long the optic will last and what it will do while you are on the move.


Let’s talk more about durability, toughness, and size. These items matter and will impact the way you navigate the use of the product on the move. The winner should be tough, able to withstand extreme circumstances, and small enough to carry around without impacting your vision.

Trijicon MRO

First, the Trijicon MRO. This brand is one of the best when it comes to optics, and they are famous for their strength. The military has put the Trijicon ACOG to work for years, proving just how strong Trijicon products can be.


The MRO, which stands for “Miniature Rifle Optic”, is another powerful addition to the Trijicon lineup. It has a housing made from 7075-T6 aluminum, built to withstand any circumstances. The windage and elevation turrets sit inside the site housing, keeping them safe from breakage or unexpected spinning.


This product is also waterproof, beneficial for those who like to put themselves in chaotic circumstances. It can be submerged in up to 100 feet of water for a short time. The product is also 4.1 ounces and shockproof, able to handle the recoil from shotguns, high-powered rifles, and pistol-caliber carbines with ease.


We’ve talked about the Trijicon MRO. Now, it’s time for the durability of the Trijicon RMR.

Trijicon RMR

The Trijicon RMR, which stands for “Ruggedized Miniature Reflex Sight”, is another durable option from the Trijicon brand. It’s a miniature open-style reflex sight, designed to withstand harsh circumstances with ease.


The RMR is made from a forged military-grade aluminum alloy, designed to keep the product in top-notch shape at all times. The windage and elevation turrets are inside and recessed into the site housing, ensuring they don’t suffer damage or unexpected movement.


Most people reported quality shock and recoil handling, but there were some issues with the first iterations of this product.


The RMR Type 1 has reported troubles with the reticle flickering on and off when mounted on pistol slides. This trouble was revealed to be an issue with the battery connection, which fixed itself with the release of the RMR Type 2.


The RMR Type 2 is simple to mount and will withstand anything. It weighs 1.17 ounces and will deal with the recoil from pistol caliber carbines, high-powered rifles, shotguns, and pistol slide mounts.


However, it’s critical to note that the RMR is an open-style sight. Although this design has its benefits, it does leave a large open area where mud and other grime could make their way inside. If enough fills the system, it will block the emitter’s projection ability on your reticle.


Due to the open-sight style, we have to name the Trijicon MRO as the winner. It will remain intact for much longer.


We’ve covered the strength and size of each product. Now, let’s move forward to the lens clarity and reticle.

Lens Clarity And Reticle

The lens clarity and reticle have an impact on what you can see through your optic. If they aren’t quality, you don’t have much luck with your product on the move.


The MRO and RMR each come from a brand with a trusted history in lens clarity and reticle. However, only one product can come out on top when we put them head-to-head for your benefit.

Trijicon MRO

First up is the Trijicon MRO. It has excellent lens clarity, so users won’t struggle.


Trijicon reportedly puts a coating on their lenses to strengthen them and provide excellent contrast for viewers looking through the lens. As a result, you notice a slight blue tint when peering through the eyepiece, but it isn’t too distracting.


This product also boasts a 25mm objective lens. With that number, you get an excellent field of view.

Trijicon RMR

Again, the Trijicon RMR has excellent lens clarity. It also has a slight blue tint, but it isn’t too much for the average viewer. The RMR boasts a 3.25 dot reticle or a 6.5 dot reticle for users.


Although the Trijicon RMR does well, we have to give this award to the Trijicon MRO once again. It’s tricky to beat the 25mm objective lens for the ultimate hunting experience.

Lens clarity and reticle are critical. However, they won’t work well without battery power and excellent brightness settings.

Battery Life And Brightness Settings

The battery life and brightness setting are crucial to help users see what is going on in the lenses. If the sight has a poor battery life and bad brightness settings, it’s tricky to get value out of your investment.


Let’s talk more about the battery life and brightness offered in each product. The more you know, the easier it will be to determine which is the right choice for your life.

Trijicon MRO

The Trijicon MRO operates with a CR2032 battery. This device can power the sight for an incredible five years of continuous use if placed on daylight brightness setting three.


The system has five daylight settings, two night vision options, and one extra bright. It’s a thorough system, ready to adjust to any needs.


How does the RMR compare? Let’s see.

The Trijicon RMR works with a CR2032 battery, which will power the system for four years. It has eight daylight brightness settings, two night vision settings, and one extra-bright setting.


The Trijicon MRO is the winner here, thanks to the duration of the battery light and multiple settings. It’s a quality system.


Next, let’s talk about the additional accessories with each sight. These helps determine the value you get from the product.

Extra Accessories Included With The Optic

Next, let’s look at the additional accessories included with each product. These are bonuses on top of the optic your order, added to take the system to another level.


Extra accessories add value to your investment. Each Trijicon product offers something different to users.

Trijicon MRO

The Trijicon MRO boasts several options for users. You can invest in a version with no mount, a factory low mount, a lower ⅓ cowitness mount, or an absolute cowitness mount. There are many accessory options to select with this product.


How does the RMR compare? It has many similarities.

Trijicon RMR

The Trijicon RMR offers the same mounting options as the MRO. You can get no mount, a factory low mount, a lower ⅓ cowitness mount, or an absolute cowitness mount. It’s the same availability as the Trijicon MRO.


This category is a tie. There is no winner when considering the additional accessories with each product.


Next, let’s talk about price. This item is one of the most vital categories to many people.

Price Comparison

Price is also critical to consider. Some people aren’t willing to spend more than their budget, and that’s okay. There is something for everyone here.


The MRO is less expensive, typically by $50-$70. The RMR will make more of a dent in your pocket.


The Trijicon MRO is the winner for the price. It’s much easier to manage.


We’ve talked a lot about the RMR and MRO. Now - which comes out on top? Who wins?


Overall, the winner is the Trijicon MRO. Although both are excellent products, the MRO beats the RMR in almost every category.


If you want a scope, go with the MRO. It won’t let you down.
