The Trijicon MRO (Miniature Rifle Optic) is a sealed reflex sight designed to be used on rifles, carbines, and shotguns, to provide fast target acquisition. It features a 2 MOA (Minute of Angle) 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” is a diagonal line.

Trijicon products are always top notch. I must have received one that made it past the QC inspection. As usual, Primary Arms customer service was outstanding and issued me an RA so I could get a replacement.
<br>Thank you for that extra information you told us during our conversation. Please let us know if there is anything else we may assist you with.

Crisp and Clear

I’ve wanted one for the longest and found it here for a great price. Optic is crisp clear and looks great on my rifle.

Perfect for AR-9 build

by -

Mixed reviews on the Trijicon MRO had me debating this along with several other Dot Optics but I'm thrilled with this! Mounted on my OD Green build the green option gives a very nice compliment to the build and great contrast for target acquisition. Paired with MBUS sights that line up perfectly.
<br>Sight picture is really clear and the slightly larger front sense helps bring in light. One thing I will note is that there is a miniscule zoom on your target, not anything that would inhibit your shooting but enough to notice. Quality product from Trijicon and for just sub $400 purchase it was really worth it.
<br>I also purchased the lens/housing cover sold by Trijicon that fits nicely, however incredibly difficult to put on since the fit is so tight (that's not ever going to come off, like, ever lol).
<br>If my AR Pistol had more room on the pic-rail I'd consider pairing with a magnifier, but chances are your favorite magnifier would work just fine with it.

Great red dot

This red dot is tough, reliable and compact. Works great on my AR pistol or rifle.
