The Trijicon MRO (Miniature Rifle Optic) has been designed from the ground up to provide the greatest possible viewing area in a compact form factor that promotes both-eyes-open shooting. This helps increase situational awareness and reduces the time needed to engage targets even in non-standard shooting positions. The best is the increased field of view comes with only a minimal size increase, keeping the Trijicon MRO a lightweight optic that won't slow you down.

Unbeatable in so many ways

Phenomenal red dot, very happy with it and when ordering having the option to pair with the mount I wanted. Primary Arms is great to deal with, super fast shipping. Thanks!

Bomb-Proof Red Dot.

When you first get the MRO you'll immediately notice how well built it is. Made from 7075-T6 forged aluminum, the thing is made to last. I paired mine with a Geissele Mount and it's rock solid. Some people complain about the tint, and it's only noticeable indoors only if you look for it. I couldn't really notice any tint outside in the daylight. The tint is not a problem for me. My only "complaint" i have is that the adjustment turrets might be a little to easy to move, i would prefer if they were stiffer. Thought they haven't moved and i doubt they ever will. If anyone is wondering i received a 130k+ serial number.

Great dot, great price


After a few weeks of searching, PA had the lowest price for the Trijicon MRO. Got it via USPS within 4 business days. Serial # is 131k+, so it is the most up to date version

Trijicon nothing else to really say

Primary shipped super fast. (I live in Louisiana, it took one day). Crisp dot, clear optic, very solid. I have one on most of my PCCs. My favorite close range optic for price and quality. You’ll be happy you got one. They also have the best prices.

Fast shipping, competitive price and quality red dot to throw on my arsenal 107. Check out mounting options as well...discounted with purchase of optic.

Double Vision

Shooting with both eyes open makes precision shots difficult due to seeing two of the target. I'm not the only one with this problem. See hoplopfheil review.
<br>I thought it might be something I got used to. However, the more I shoot with this optic, the more it bugs me.

Amazing Red Dot

I'm very happy with the MRO. Quality glass and a fantastic field of view.

Great product. Poor service.

Ordered the MRO. Trijicon quality so I have no complaints there. Unit is supposed to come with a working battery. It didn’t. Not a big deal except all my electronics don’t use those types of batteries. Contacted the store. No response. I had to go out and find some on my own. Not a big, big deal but telling.
<br>It was good to speak to you on this and please let us know if there is anything else we may help you with.
