I often get questions about which RMR a
buyer should add to their pistol. There is no easy answer. It depends
on what the end user wants as each has advantages and liabilities. We
can divide existing Trijicon RMRs into three groups.
First is the Dual Illuminated units.
These are comprised of the RM03 (13 MOA Amber Dot), RM04 (7 MOA Amber
Dot), RM05 (9 MOA Amber Dot), RM05G (9 MOA Green Dot), RM08 (13 MOA
Amber Triangle), and RM08G (13 MOA Green Triangle). They are all within
a few dollars of each other, but the Dual Illuminated are the lowest
cost RMRs. They can be identified by the grey plastic shroud that wraps
around what some call the "cat ears" on the RMR.
The advantage of these is that they will
never need a battery since they run on fiber optics that gather
existing light and fuse it onto the dot or triangle. In reduced light
where the fiber optic has collected nothing, an internal tritium element
powers the dot. For some of our customers that tend to travel in the
Third World where batteries are simply not available, we suggest this
option. The fiber optic is a passive unit that will last forever, and
the Tritium should last a decade or so.
This is not without disadvantages
however. We have found that if shooting from a darkened environment
into a lit environments (say a dark room into a lit hallway...or from a
darkened house out into the sunlit exterior), there is an effect called
washout. What happens is that there is not sufficient light to activate
the fiber optic, and it is not sufficiently dark to activate the
tritium. The dot does not disappear, but it is quite faint.
As well, when operating with a weapon
mounted light, or any of the flashlight shooting systems, as soon as the
flashlight is turned on, the shooter will experience that washout
effect. This is of course immediately nullified by the shooter
transitioning to the iron sights seen in coincidence with the dot, but
the effect can be a liability under the mentioned conditions.
Second are the two LED Constant On
models, the RM01 and RM02, in 3.25 MOA, and 6.5 MOA respectively. They
are identified by no grey plastic shroud and instead slick black sides.
These are constant on all the time and have an internal brightness
monitor that increases or decreases brightness according to ambient
conditions. This is a great feature and most will find this a "best
buy" unit in either MOA. The batteries will last a good long time, but
we recommend they be changed once a year. Pick a date and change the
One thing that I have experienced with
the Constant On LED Models is that in the mile high AZ wilderness, with
the ultra bright sunlight, oftentimes the RM01/RM02 is not as bright as
I'd like it. But that is the only drawback, if it can be called that.
And that brings us to the RM06 and RM07 (3.25 MOA and 6.5 MOA
These are like the Constant On LED
models and share all their characteristics with the addition of an
On-Off Switch that resides on the sides of the RMR. This allows me to
increase the brightness or to decrease it. I will refer you to the
manual for details, but suffice to say that I can increase the
brightness to a high level so it is exceedingly visible even at high
noon on a cloudless day at 7,000 feet. Yet, I can also make the dot
nearly invisible unless I am using my PVS-14 night vision unit.
Similarly, I can simply shut the unit off for travel, or for iron sight
training should I wish to do so. These are the most costly of the RMR
That is it in a nutshell. Which ones do
I use? I have a couple of RM06 on some Glock 17s intended for long
range shooting, and RM07 on my Glock 19s.
