Both of the red dot optics are top-notch products. In this article, we compare Aimpoint Pro vs Trijicon MRO, where they have very different optic body types.

The Aimpoint Pro has long tube profile and the Trijicon MRO is shorter. The Trijicon MRO has the biggest field of view about 1X25mm, where the Aimpoint PRO only has 1X23 mm. In addition, both optics have great field track record.

If field of view and compactness are what you're looking for, go with the Trijicon MRO‘s.

At the end of this post, you will learn how they look, price, features, and benefits to see which one works best for you.

Practical Applications

Aimpoint PRO SWAT

The Aimpoint PRO red dot optic is probably one of the most memorable optic designs showed in movies, video games and real-life law enforcement and military unit. The PRO stands for Patrol Rifle Optic, it's ready to go optic at a budget-friendly price, which is something very appealing to law enforcement units.

The Trijicon MRO gives the shooter ambidextrous control as the knob is on top of the optic, which is easier to operate with both hands. The Aimpoint PRO will be a little more difficult for left-handed people.

The sight is similar to the Aimpoint COMP series red dot sights and it's great for flat-top AR15, M4 rifles, and it requires a 30mm ring mount, but the Aimpoint PRO comes with a factory mount to save you more money.

The Trijicon MRO is a much beefier and low profile optic, perfect for CQB and low profile rifles. It's very popular for short barrel rifles, close-range hunting rifles, and other personal defense weapons.

Objective Lens & Field of View


Aimpoint PRO VS Trijicon MRO objective lens field of view

Image Referenced GunsandAmmo

The size of the objective lens determines how much fields of view width you get. For magnified optics the bigger the objective lens the more light the scope can capture to brighten the image.

But for a non-magnified red dot optic, it works differently. The larger the objective lens the faster target pick up speed, which is very useful when shooting on the move or from improvised shooting positions.

Tilted Objective Lens

If you pay attention to both of the sights, their objective lens is off-axis and looks tilted.

The reason for that is to ensure parallax-free viewing experience and allows for the light beam from the LED emitter to bounce off the surface and reflect the reticle to the shooter.

The Trijicon MRO has a 1X25 mm diameter lens, which is much bigger than the Aimpoint PRO.

As far as looking through the optic, the MRO has a unique tapered body profile that eliminates the tube effect and it feels very comfortable.

Lens Cap Protection

The Trijicon MRO doesn't come with a lens cap, but the Aimpoint PRO does right out of the box. What I like about the Aimpoint PRO lens cover is that it see-through, meaning you can still acquire the sight if the lens cap is closed.

For a hunting scenario, this is extremely helpful and saves time engaging a target quickly without having to worry about whether your scope lens is closed or open.

Battery Life

The battery of these two optics doesn't even need to be talked about. They last a very long time without the need to change their batteries, and they're always on to keep you in the fight longer.

Trijicon MRO uses a single CR2032 battery that lasts a very long time, and it actually lasts longer than the Aimpoint PRO by 2 extra years while setting on brightness level 7.

Aimpoint PRO uses a 1/3N battery (2L76), they are rare to find unless you go to a battery store, they last a very long time for the Aimpoint. You can buy 1/3N 3V battery here on Amazon that will save you so much time out in the store looking for it.

Reticle Option

The Trijicon MRO offers 2 MOA size red and green dot selections. You can't switch between them which means you need to pick only one model. Generally speaking, the green is much easier to see under the bright sun. Personally I noticed no difference in them, and I prefer just using the red reticle.

The Aimpoint PRO only offers a 2 MOA dot size red dot.

Both of the optics have adequate brightness settings control.

  • Aimpoint PRO – 8 brightness settings, lowest 2 for night vision
  • Trijicon MRO – 10 brightness settings, lowest 4 for Night Vision

MOA Dot Size

The 2 MOA dot is a very standard dot size for a combat optic, which balances long-distance and close-range shooting applications.

Night Vision Mode

Personally I never use the night vision for the type of shootings I do. I would highly recommend checking out TNVC for more information.


Mount Options

Trijicon MRO Mount LaRue Tactical

The Aimpoint PRO accepts any 30 mm scope ring mount. When you buy an Aimpoint PRO you will receive a QRP2 mount from Aimpoint, and you can adjust the spacer to raise or lower the optic co-witness height to your preference.

However, you don't have to stick with that mount, in fact, you can go with other better mounts.

The Trijicon MRO accepts other aftermarket mounts as well.

  • Low mount
  • Absolute co-witness mount
  • Lower 1/3rd co-witness mount
  • Quick release mount

Some of the best optic mounts that I recommend for the Aimpoint PRO and Trijicon MRO is from LaRue Tactical, Scalarworks and American Defense.

Optic Accuracy

Both optics are very accurate using their 2 MOA dot size reticles. When perfect shooting fundamentals are applied, any gun with one of the optics attached will get a 1 – 2″ group at 100 yards using a 5.56mm round.

Because both optics are very rugged and strong, they work well on machine guns as well. Any repeated sharp recoil will hold the zero no matter what.

Note: in order to ensure zero, please make sure each screw on the mount is set to the exact recommended factory torque spec. You can do that with the Wheeler Torque Wrench an you can buy it here.

  • 30 mm ring mount – 15 – 20 in-lb
  • Trijicon MRO TX20 Screws – 12 – 15 in-lb on each screw

Use some red locktite

Reticle Parallax

The Aimpoint PRO has less parallax than the Trijicon MRO. Red dot sight in generally has way worse parallax issue than holographic sights due to the dot projection method.

When the target is close, the parallax shift becomes more sensitive.

As far as parallax goes, the Aimpoint PRO is a way better optic.

Check out Greeney Tactical for a detailed parallax test they have done here.


External Features

The Trijicon MRO is definitely more compact than the Aimpoint PRO, and its tapered body design gives the shooter a great view without any tube effect is a huge added feature in the optic industry. Now Vortex and Leupold are doing it with their UH-1 and LCO.

The Aimpoint PRO is an old design that is still very popular on the market.

If you're looking for compactness, go with the Trijicon MRO. If you want the old school optic looks, then go with the Aimpoint PRO.

Weight & Construction

The size of the Trijicon MRO is definitely something CQB shooters love because it's so much lighter than other optics. The MRO is shorter, lighter and can deliver the same performance as other optics. Weighting



The Aimpoint PRO and Trijicon MRO are both affordable optics on the market today. They come with a mount and the entire package is less than $600. If you're looking at these two optics tells us that you want something nice but without spending all of your money.

The Aimpoint PRO is definitely a hot selling product and the Trijicon MRO is also a great option.


Wrap Up

The Aimpoint PRO is an awesome optic that is still very popular in the gun community when when compared to the new Trijicon MRO. I had to say the Trijicon MRO is a better and newer optic for anyone getting started in shooting.

Wider field of view and fast target acquisition speed are things that are very appealing to tactical shooters and hunters. Trijicon MRO's 1X25mm objective lens and the wide field of view are perfect for hunters and range goers for many years to come.

Both optics are proven optics, but as far as size and durability go, the Trijicon MRO is a better option.
