Mini Red Dot: Trijicon RMR06 3.25 MOA Review


Trijicon RM06 RMR on a handgun

Trijicon is famed for their tough as nails ACOG optic, which is the standard of the United States Marine Corps. Trijicon does produce a wide variety of combat and sporting optics outside of the ACOG, with the RMR being one of these optics. The RMR, or ruggedized miniature reflex sight, is a very small and compact optic designed for close range user. The RMR is small enough to be used on any platform including pistols and revolvers.


First Look Out of The Box

The Trijicon RMR comes in the box I expect for a six hundred dollar optic. It’s a plastic/polymer case with foam on the inside. It might not be a Pelican case, but it’s better than cardboard. You get the optic and the included manual, registration and warranty stuff and a lens cloth. It doesn’t have a mount, though, for anything. This may be in part to the fact this thing gets mounted on rifles with pic rails, on handguns, and even other optics. I would still think a basic pic mount could be included. The Trijicon website shows a ton of different mounting options for the Trijicon RMR.


The RMR runs off a single CR 2032 battery that is installed on the bottom of the optic. This means to change the battery you’ll have to dismount it as necessary. There is a model of RMR that uses fiber optics and tritium for a battery free optic, but my one ain’t it. The advantage is after hours of exposure in a dark environment the dot is still bright as possible.

The dot is 3.5 MOA so it’s on the smaller side of red dots, it is nice and bright and amber in color. Amber is very distinct color, not one found in nature, and it’s not often used by humans in urban settings. This keeps the dot distinctive on most backgrounds, and it’s easy on the eyes. The optic feels good in the hand, and is very well built, but weighs only 1.2 ounces with battery.

Now It`s Range Time

I took a different route with this testing and for the first time mounted the Trijicon RMR to a Glock 40 MOS in 10mm. This is a new weapon for me, and the first time I have placed an optic on it. I have some limited experience with mounting and using optics on handguns but not a ton. Mounting the optic is a bit more complicated than mounting optic on a traditional rifle. It’s simple but is a lot different. Enough so that I had to follow instructions and figure out which plate to install and how to exactly do it.


Once it was mounted a quick zeroing took place. The controls on the Trijicon are easy to dial in, but a small screwdriver makes life much easier. It’s pretty simple to see the dot as you twist the screw and observe its movement. Shoot NC targets make this a dot easier, and a lot faster to use. The shooting was done at an indoor pistol range with a max range of twenty-five yards.


The main strength of a RDS on a handgun is how fast the user can acquire a target at extended range. 25 yards with a handgun is long range shooting with a handgun for most people that aren’t professionals, myself included. Our ultimate goal was to expand to reach out the 25 yards, but we warmed up with shooting at 10 yards.

10 Yards

Starting from the low ready we attempted to get on target and place one round in the 9th ring or better of a standard NRA pistol target in under 1.5 seconds. This is not a difficult challenge, but it’s not exactly easy. I feel it’s a good baseline.

The first few times I found tricky, I am used to iron sights and out of instinct I was looking for the iron sights. I found them since the Glock MOS system retains the irons. This threw me off several times. Not an optic issue, a training issue. What was an optic issue was finding the small 3.5 MOA dot. When it comes to close range speed shooting the bigger the dot the better with handgun style optics.

It took an extra half-second or so to find the small 3.5 MOA dot on the Trijicon. Of course, with practice speed and accuracy improved. What the dot really helped was one handed shooting, and even more so with off-handed shooting. I was faster with the dot and optic with one hand than I was with iron sights.

20-25 Yards

Once we backed the target to 20 and 25 yards you start to see how much an improvement the dot is over iron sights. The small 3.5 MOA dot makes seeing and hitting the target at this extended range much easier, and faster, and follow up shots were faster. Like most indoor ranges this one wasn’t well lit, so the glow of the Trijicon RMR’s dot stood out very well, better than standard iron sights could hope to.

The lenses are clear, but this isn’t that important since you are using both of your eyes and the lenses clarity isn’t that important. We fired three hundred rounds of full powered 10mm loads and the dot stayed zeroed the entire time. We fired 20 powerful hunting hand loads and had the same result. This RMR can take the back and forth force of heavy recoil very well.

The Trijicon RMR is a great little optic while I chose to use it on a handgun it would be a solid optic for a shotgun or carbine designed for close range. The few drawbacks I could find was the fact I have to remove the optic to change its battery, and the optic is limited for close range use.

  1. This is very disappointing. I saw this at the 2008 SHOT show and was relaly excited about it. I worked for a company at the time and tried to convince them to make a gun in that caliber, but they decided it would be too difficult and wouldn’t sell well enough. Now Aguila has all this ammo everywhere and nobody to buy it. T/C listed it in their catalog that year, and even listed that as an available caliber on their website, but then they got bought out, and I’m sure the project got scrapped. Too bad.
