It is also very aesthetically pleasing and has a matte black anodized finish while being corrosion resistant. 

Brightness Configuration:

The brightness settings of the Trijicon MRO mount have six modes, including two-night vision brightness modes, which are on the rotational dial located at the top of the scope. It is one of the Trijicon MRO features, which makes it quite ambidextrous. This also allows for the brightness adjustments without leaving grip and trigger hold.

While using it during daylight conditions, the settings 4 and 5 is ideal. When the 5 environment is not entirely satisfactory for the situation, then there is also six sets, but it’s often too overpowered. There are also two other additional settings for night vision purposes. There is less information about these two settings except that these two are essential for night time aiming of the MRO optic.

Battery life:

The battery holder has its convenient position on top of the Trijicon MRO illumination dial. The cover can be unscrewed quite easily by just using a coin and a small screwdriver. There is also a warning sign which says to install the battery correctly. If this is not followed, then it will damage the little metal teeth which are there to hold the battery securely in place.

CR2032 lithium-ion batteries are used for this scope. The Trijicon MRO battery life has a backup of 5 years, even if it is used continuously. Although if you set its brightness level to maximum, then it will drain the battery in just 25 days. However, for this to happen, its brightness should stay at settings 3. While purchasing this product, the batteries are provided free of cost. 

Aim Adjustment:

The turrets of windage and elevation adjustments can be flushed and adjusted by using a coin or a screwdriver, or just with the rim of the ammo casting. While these windage turrets are flushed, it becomes quite difficult for the user to move or brush them.

Covering these with caps is not necessary, so you don’t have to worry about losing them. All these MRO sight features make it quite superior ergonomically in comparison to other competitors in the market. 


The objective lens size of this product makes it stand out from other available optical scopes. Most of the red dot sights which are in the market have an objective lens of just 20 mm. However, the Trijicon MRO optic lens is available in 25mm which gives it an added 20% improvement of its sight picture quality.

This gives it a better and broader viewing area, thus eliminating and tunneling effect. This significantly reduces the chances of eye fatigue. The lens of this scope grants eye relief for a longer time and is easy for proper eye vision.

The-patrol variant:

There is also a new model with an improved build and more features. It was introduced to the market this year and has been on sale for several months now. It is a bit more costly than the base variant, but its additional features justify the price. In terms of looks, it is quite similar to its original model.

Features Of MRO Patrol:

Trijicon Mro Scope Review

Without the mount, this model weighs about 5.1 oz. It is also 4.1 inches longer than the original one, and because of this, the ‘patrol’ variant is a little bit heavier. Two new mro sight attachments can be installed on to this model because it has extra metal rings on the ends of each of its housings. 

  • There is a durable lens flip-up cap for protecting and covering the lens. 
  • It also has an ARD(anti-reflective device), which is capable of reducing the reflection and glare during the day time. During the night, this feature ensures that the lens reflection does not disclose your position if some kind of light falls on it. 

Another advantage of it is that this variant comes with its batteries pre-installed. While in the original one, the user had to install batteries manually. 

MRO patrol also has a quick release(QR) mount system, which is not included in the original MRO. The QR system lightens the tension between your rifle’s Picatinny tail and the mount. Because of this option, you can dismount or remount the red dot sights at a faster rate. 

Witness mounts:

Trijicon Mro Scope Review

Mounts come in two classes, which are Absolute co-witness and Lower ⅓ co-witness ones. 

Absolute co-witness:

This mount allows the optic set up in such a manner that the reticle and the Aimpoint come to the middle of the back and frontal iron sights. For short height individuals, this setup is an ideal one. The only mro problems with this setup are that the view looks a bit cluttered. This setup might not work for taller people. 

Lower ⅓ co-witness:

This mount raises the optic to a quarter of an inch from the iron sights. This setup is suitable for bigger and taller people. The rifles which have a static front and rear iron sights are ideal for this mount. 

The difference between

Aimpoint pro and Trijicon MRO

Even if these two products are quite similar in their features, but there are some apparent differences between the two. Here we will discuss Aimpoint Pro vs. Trijicon MRO key differences. 

  • MRO has a slightly broader point of view than Aimpoint pro besides its red dot of it is somewhat sharper. 
  • Aimpoint Pro has its brightness control and battery space located on the left side. This makes it difficult for right-handed individuals to adjust the Aimpoint’s brightness, whereas the MRO has its brightness rotary dial placed on the top side, which makes it easier for one-handed control. 
  • MRO has a much longer battery backup in comparison to Aimpoint pro. You can also easily find MRO’s spare battery in the market in terms of its availability. 

MRO pros and cons:

Besides so many features of this product, there are some Trijicon MRO problems. We will now look at some of its pros and cons, which are:


  • The red dot is sharp.
  • It is compact and light.
  • Has a decent battery life.
  • Easy one-handed brightness control.


  • It has a high rate of failure.
  • The old models have a slight fishbowl effect.

To conclude..

Although there are quite a lot of red dots that are available at a cheaper rate but sometimes it is wise to choose an allrounder. MRO may be expensive, but it fulfills a single combat rifle setup for any military combat or hunting situations.
