“The only thing worse than being blind is having sight but no vision. – Helen Keller

The MRO (Miniature Rifle Optic) is a red dot-style sight introduced by Trijicon in 2015. It’s their answer to the Aimpoint style of micro red dot optics.

The first thing you notice is its large objective lens, and that feature sets the MRO apart from other micro red dots. At 25mm, its large enough to dramatically minimize the constricted feeling of “tube view” you get with other micro sights. With the objective lens of the MRO being larger than the ocular lens, the optic body is tapered such that it fits naturally to the operators vision, creating a wider field of view and reducing blind spots.

The Trijicon ACOG is well known for its durability, and if all the YouTube videos of MRO drop tests are any indication, durability is not an issue. Thus far, mine has run flawlessly!

On a related note, during a recent rifle program I had an EOTech optic fail mid-drill. Not only did it fail, but it failed in a way that prohibited the use of my co-witnessing iron sights! The EOTech is a high quality sight, and recommended. However, all optics, like all firearms, will eventually break, and this is a perfect example why all battle rifle optics should be equipped with a quick disconnect (QD) mount.  Trijicon and LaRue Tactical both make quality QD mounts for the MRO, and both hold zero when removed and reinstalled.



The MRO is available with either a red or green dot, my preference being red. However, those with some color blindness will probably see the green dot better. The battery life is said to be 5 years on the red dot medium setting; time will tell. Interestingly, the battery life with the green dot is reported to be 1 year on the same setting.

I’m looking forward to getting more time behind the MRO. So far, I’m well pleased and I highly recommend it!
