Trijicon MRO Review: If You Don’t Have it Yet, Should You Get It?

Last Updated on January 12, 2021.

Gun owners can be just as picky about their optics as they are about their firearms themselves. And if you do a lot of shooting, then you know that not having the right product for the situation can lead to a very unenjoyable time in the field. What about when you need red-dot accuracy and fast target acquisition? Enter the Trijicon Miniature Rifle Optic.

The brand is well-known for consistently putting out quality items, but historically they’ve dealt with magnification. In 2015, however, that all changed, and this product was born.


  • High value for price point
  • Performance and quality
  • Everything needed to mount the optic is included
  • 5-minute setup
  • Wide variety of brightness settings including night vision
  • Ambidextrous operation
  • Infinite eye relief
  • Under $500


  • Has a tiny amount of magnification even though advertised as a 0-mag
  • Brightness settings may not be adequate for super bright desert environments
  • On high brightness, a red halo is visible
  • The emitter is located at the 11 o’clock position and can be visible in some lighting; proper head position can mitigate this
  • Still not a ‘budget’ product

In a word, yes. It offers several features that take it head and shoulders above the corresponding Aimpoint products that have held the market for a few years. For shooters looking for the accuracy of the red-dot optics without any magnification, the MRO is worth the buy.

For its price point – under $500 – if you don’t already own it, you should.

It is billed as a 1X optic. Its sole purpose is to offer you red-dot accuracy, and it does that job very well under a wide variety of situations, while still holding up to weather, general wear, and even abuse.

It sports eight adjustable brightness settings ranging from daylight to super bright and even night vision. Left-handed shooters will appreciate the ambidextrous control for those brightness settings, leaving your trigger hand free to keep shooting regardless of lighting.

The parallax-free aperture helps with target acquisition because the front glass is 25mm – larger than most other red-dot units. In fact, its field of vision is 44% bigger than most red-dot scopes – even the ones that cost much more.

That larger front glass makes it slightly great in size than its relative counterpart, the Aimpoint Micro. Even with the front opening, however, the overall footprint is still well within the ‘micro’ expectation.

The glass is USA-made, and are designed to produce zero reflections across all light conditions, meaning less chance of you spooking your target. The multi-coated lens also ensures that your eye gets the maximum amount of light available, giving you a better sight picture.

Lastly, it is made out of 7075-T6 aluminum – the same grade used on aircraft. That’s a significant improvement over the 6061 used in many others and ensures that it can take a beating in the field.

Our Opinion

No optic is perfect, but this Trijicon model gets close to its price point.

Even with just the ACOG-level quality, ambidextrous operation and long battery life, this product would be a solid buy. When you include the rest of its features, it becomes a must-have for shooters looking for fast target acquisition.

It just does its job with no fuss. Once it’s zeroed, it’ll stay that way, regardless of the abuse you heap on it in the field.

Even its few drawbacks, such as the halo on high-brightness settings, aren’t anything not already found in most other red-dot optics, and the placement of the emitter isn’t insurmountable either.

Other Options Worth Looking At

Even beginners looking to hone their skills can use this unit but if you’re looking for other optics, the Aimpoint Carbine Optic, or ACO, is a worthy competitor. It’s slightly lower on the price scale, under $400, but comes with nine brightness settings and up to 1-year always-on battery life.

The Aimpoint Micro T-2 is another option and is this model’s main competition – even though it’s significantly more expensive. It has an 18mm aperture, flip-up lens covers and a 2MOA dot that runs five years on one battery.
