The Trijicon MRO Green Dot Sight 2 MOA is a sealed reflex sight designed to be used on rifles, carbines, and shotguns, to provide fast target acquisition. The MRO (Miniature Rifle Optic) features a 2 MOA green dot for optimal visibility in low light and transitional lighting conditions. The enlarged objective lens and tapered light path allows for a wider range of view resulting in a smaller overall size and increased situational awareness. The advanced lens coatings and electronics provide an exceptionally clear sight picture and crisp dot.

Green dot flickering

by -

Elected to go with another MRO for a .300 blackout rifle, I purchased this on 1/21 from PA and went to shoot it this past weekend and my green dot is flickering? I'd not even shot it yet and had left it on power 4 setting.. A bit concerning when thinking about reliability vs the big name competitor. Not sure if this is electrical or just needs a new battery, sure hope they last longer than 2 weeks.

Clearer glass than red model

by -

I have a red one that I didn’t like because it had a darker tint to the glass but I elected to try the green model. Much clearer glass and the green dot is easier on the eye than the red. It’s not suuuuper green.

Solid optic, Trijicon nailed this one


Glass is clear, does not have the annoying blue tint the red dot version has. The real standout feature of the MRO is its large objective lens, you can see so much more of the target than an aimpoint style dot sight. The dot on this model is more of a yellowish-green. I think it's a little more practical than the super pure green dot sights such as the holosun or EOtech because you can see past the optic a little easier (not get hung up on the intensity of the green). I love this optic and paired with the scalarworks mount looks great.

For the money


For the money you can not go wrong. I’ve got 4 CR2032 batteries. That equals 20 years of battery life. “Forged in the same fire as our battle proven acog”. I did 2 tours over seas in the infantry and always had my ACOG. When I brought it to my eye it never failed and never lost zero. Deciding to get a high quality optic on a civilian AR-15, I immediately go to Trijicon. For around $500 (including a mount) your getting the best bang for your buck. Durability, reliability, and pure quality you can not beat. Field of view is way better than Aimpoint, and battery life is better than eotech. Downside: that 20 year battery life or 5 years off of one single CR2032 is on brightness setting 3. Level 3 is perfect for indoors UNTIL you use a white light. All other brightness settings are not mentioned as far as battery life. Setting 4 is much better but it’s a gamble to leave it on 4 at all times. Have not tried night vision setting but for it to include night vision for $400 is amazing.

Great quality!

Holds zero easy to adjust worth every penny

Quality and reasonable price. I have a few of these.

Great product but not perfect

by -

I love the green compared to the red. However, the green dot isn't as much of a dot as it's more of a comma. That is my only complaint with this item. Everything else is top notch quality just like everything else I've had from Trijicon.

Worth waiting for.

I am very satisfied with this unit. I was expecting some blue tint on the glass but it is amazing clear. The larger lens collects more light and with the green dot it is very easy to use in all levels of light. I would definitely recommend this for a CQB item. Very happy. As for Primary Arms, quick shipping, good price, and a large inventory of in stock items. I plan on buying from them in the future.

Tough & Accurate


I purchased mine here from Primary Arms about three months ago, and have left the dial on 3-4 for the duration (other than when at the range in full sunlight where I turned it up to 5). I've not yet had a problem with the battery or the emitter in anyway. Still as bright as day one. I expect to get 6-12 months of use, which is fine for a device that is always on, and always bright enough to see.

I have it mounted on my .300blk pistol and it's been to the range 4 or 5 times. I've fired about 600 rounds using this optic. It only took me about 10 minutes (and to get it sighted in, then other 5 to bring the BUIS on target. I've been shooting Magtech 123gr rounds and Frontier 126gr, and this thing is a tac-driver. My brother and I can knock down clothes pins at 25 and 50 yards.

I've not had to re-zero it, yet, and I carry this thing everywhere. It's a tough little pistol build that I can throw in a bag, and go anywhere, knowing that it'll cover my keister when I need it to.

Top Red Dot

by -

The MRO is an extremely rugged optic. The Green Dot is an added feature that allows some to see the dot better. It’s easy to zero with the exposed turrets.
The ADM mount is also excellent, it easily adjusts to any Picatinny rail providing a secure mount. The lower 1/3 rd cowitness aligns well with my 3X Trijicon magnifier making for a very effective package.
