Earlier this year I was looking for a new sight for my FS2000 I picked up last fall—I’d been using a Holosun 403C I’d borrowed off my Kriss Vector SBR but needed a permanent solution. I had intended to use my Meprolight M5 sight when I bought the FS2k but that sits too high for me—the FN has a raised rail that makes sights that work well on ARs or (especially) Tavors sit too high for me. I’d found that the Holosun sat perfectly—just a bit higher than an Aimpoint Micro, which sits a bit too low.
I’d seen a few posts about the MRO (it’s a 2 MOA sight), and I’d had good luck before with a few ACOGs and RMRs (now down to just one ACOG) so I thought I’d give it a try. The problems that the SRS had, plus a few online reports of parallax and reflection issues with the MRO gave me a bit of concern, but I thought I’d try it anyway.
The sight comes in Trijicon’s usual hard-shell case and includes the hex key, battery, manual, lens cloth, plus the traditional sticker. Lens covers or a scope coat would have been a nice addition
The first thing I noticed was that it was smaller than pictures made it look—it’s not that much bigger than an Aimpoint Micro—and at 4.1 oz it’s only 0.8 oz heavier. Here is it compared to my Micro and Holosun sights.
The objective lens is significantly bigger, though.
Mine came with the Trijicon factory low mount—nothing fancy…just a couple of hex screws. You can also see in the picture below the windage adjustment. Unlike Aimpoints there are no caps over the adjustments.
Here’s the elevation adjustment, as well as the big brightness knob. I like how easy it is to adjust, although I’d never had a problem with the Micro’s side-mounted knob. You can also see the slot for the battery cover on top of the brightness knob.
Interestingly, there are two “off” positions. One between the 2 and 3, and one below the 1. I guess the theory being that if you’re just using it in daylight use can turn it off after the 3 and have it ready again with fewer clicks.
Looking through the sight it does exhibit a bit of a “lens-y” effect that RMRs do, with maybe a slight bit of magnification. The effect didn’t bother me on the RMRs, but it is a bit more noticeable than with the Micros. There’s a slight bluish-green tint too, also similar to the Micros. One of the things I liked about the Meprolight M5 sight was the perfectly clear and distortion-free. The MRO exhibits, to my eyes, the same amount of astigmatism distortion that the Micro does—the RMR was better in this respect, but it also had a larger 3.25 MOA dot which could account for the difference.
Of course, the big claim to fame for the MRO is the larger field of view. Here it is compared to my Micro and Holosun (the greenish tint of all three sights is more prevalent in these pictures than it is with the naked eye).

The MRO does indeed have a larger field of view, but in doing a few “test sightings” with the FS2000 compared to the Micro on my Diablo it does not seem “night and day” different.
At the Range
The first range trip with the FS2000 was in May earlier this year—it was a pleasant day with temperatures about 15°C with light winds but unfortunately the black flies were out in full force. I also brought my PWS Mk107 Diablo out for comparison—it has a 2 MOA Aimpoint H1 on it. Ammunition for all shooting was 55 grain Remington FMJ from their “Freedom Bucket.”
The results were quite pleasing—I tried standing shooting at 50m and seated from a rest at 100m. The dot was very easy to pick up at brightness setting “4”—there are two brighter settings but given the brightness of the mid-day sun it’d have to be a very bright environment indeed to require it…probably something like snow or sand and bright sun.
The dot was quickly picked up…I’m not sure it’s much faster than the Micro but at least as good. There is some “lensing” in the view through the sight but it was not perceptible in use—there’s more than with the Aimpoint. The RMRs I owned had the same effect—it does not bother me. The sight did have a more noticeably bluish-green tint than the Aimpoint.
There were absolutely no spurious reflections in the sight. I even tried inducing them by standing with the sun directly behind me and aiming the rifle at the ground to maximize the amount if light behind the sight—there was nothing. I tried the same with the Aimpoint and there was a bit of a red reflection in the top left of the window—no objectionable by any means but still noticeable.
The sight adjustments were easily and accurately made—the cap-less adjustment dials are certainly convenient.
Here’s how both sight look at 100m:
Aimpoint Micro
Trijicon MRO
You can see that the Micro has a bit of lens-effect—have a look at the line where the target numbers are. The MRO has a bit more—this can be seen at the top of the backstop. As mentioned earlier, though, this was not noticed in use. The MRO exhibited less distortion at the edges than the RMRs I owned. You can also see the wide field of view with the MRO—it goes from target positions 6 to 10, while the Micro goes from targets 7 to 9. The 2 MOA dots in both sights looked identical to my eyes.
Here’s the result of the first 10 round group—it’s just a bit more than 3”, which is just a bit bigger than how well I usually do with the FS2000. I haven’t had the FS2000 out since December so I don’t feel that the sight was the issue—it was easy to hold on the sighting mark.
I’m quite happy with the sight—it worked well, and didn’t exhibit any of the negative issues I’d read.
