In Summer 2022, I picked up a Glock 48 at a local pawn shop. My plan was to mill the gun for an optic, and to see how much performance difference there is between a midsize gun, and the newer generation of slimline guns. However, I had to decide on what optic to use. As a long time fan of the Trijicon RMR, I decided to give the RMRcc a try. Since early Fall of 2022, I've been testing the RMRcc, and have a fair bit to say. So what is the RMRcc, and how well did it perform?
What is the Trijicon RMRcc?
Well, the RMRcc is the Ruggedized Miniature Reflex (for) Concealed Carry. It's a slightly smaller RMR, made for use on thinner guns. With the advent of the SIG P365 and the Glock 43X/48, a new generation of smaller optics became popular. However, most full size optics will not fit on these guns, without the use of massive adapter plates. As such, smaller optics have become the norm for these guns.
Released in late 2020, the RMRcc was Trijicon's first entry into the micro-RDS scene. I've been jokingly referring to this optic as the "80% scale RMR", or the "left in the dryer a little too long" optic. When you look at the RMRcc, what you get is an RMR, but shrunken down.
There are two models of RMRcc offered, the CC06 & CC07. The 06 is a 3.25 MOA red dot, while the 07 is 6.5 MOA. MSRP is $699, however, retail is a lot closer to $375-$450. Dimensionally, both optics measure 1.8" x .95" x .97", and with 7075 aluminum housing, weigh 1 ounce. Again, tiny optic, so tiny size.
I purchased a CC06 from Eurooptic in July of 2022, paying $410.00 for my unit. At the time, Trijicon was running a $100 mail-in rebate, so my total cost was only about $310.00. The optic shipped with the standard massive Trijicon box, with a sealer plate included. What are the features of the RMRcc?
The optic footprint is essentially a smaller RMR footprint. We've got two recoil bosses, and two screws that mount transversely into the slide. Now, the footprint isn't the same as the RMSc or Holosun K series, so keep that in mind. Controls are the same as the standard RMR, with buttons on either side, and zeroing adjustments in the same locations. Again, this is a smaller scale RMR, so you'd expect this.
One of the slight oddities of the RMRcc are the adjustments. When zeroing, the turrets move in 1 MOA adjustments. However, you only get a tactile "click" every 3 MOA of adjustment. Don't know why they did this, but I'll cover zeroing later. Internally, this is a Type 2 optic, meaning that it has fairly beefy internals, and an auto adjusting brightness mode. Thankfully, this can be turned off.
Speaking of brightness, the CC has 8 brightness settings. 6 are for daytime use, with 2 for night vision use. What drew me to the RMRcc was that it could get as bright as the standard RMR, a feature that I really, really utilize. Like its larger brother, the CC is powered by a single bottom mounted 2032 battery, with an advertised battery life of 3 years. Now, battery life advertisements are BS, as manufacturers generally give a number based on a brightness setting that is too low. I swap all of my RMR batteries annually, and we'll cover my experience here later on.
Window size is slightly smaller than a standard RMR. Despite the large "forehead" on the RMRcc, when mounted, it doesn't effect use. The blue notch filter is the same hue as the full size optic, which I dig. At risk of sounding like a broken record, this is just a shrunken RMR.
Since I began with a standard Glock 48, I mailed off my slide to Battle Werx to have it cut for the optic. I did this in September of 2022, and have been using the gun since November of 2022. So, I've got some time with it. How easy is this optic to zero, and how usable is it?
Getting On Target
The milling work done by Battle Werx was quite well done, and as such, a rubber mallet is needed to get the optic on the gun. Now, that's great, as it eliminates the optic cut as a variable for keeping the optic zeroed. As per standard for all of my RMRs, I use a sealer plate, and apply a slight amount of blue Loctite to the threads of the screws, and torque them down to specification.
Zeroing the RMRcc is an easy process. While there is only a tactile "click" every 3 MOA, I didn't find it to negatively impact zeroing the optic. I've had to zero the optic once, and then confirm zero two more times since then. Overall, the zeroing process is about the same as a standard RMR. I pulled the optic from the gun twice, with each battery swap only requiring minor adjustment to return to zero.
In use, the RMRcc performs like an RMR. I've done some of my best shooting with the RMRcc on my G48, and the RMRcc did not get in the way of doing so. For me, a piece of quality gear is something that does not impede your ability, or your growth of ability. While the window size is slightly smaller, the crispness of the reticle and ability to get extremely bright work wonderfully here. While moving from an RMR on a Glock 17 to an RMRcc on the 48, there's basically no mental hurdles to overcome. Both have the same controls, same batteries, and same look through the window.
All of the shooting that I've done with my 48 has been with the RMRcc attached. At no point did I feel like the optic was impeding my ability. A full playlist of my recorded drills can be found here. While I don't have it on camera, the RMRcc performed well under NVGs. With my PVS-31s, I was able to accurately shoot the G48. The NVG settings were honestly too dim for quick use, but the bottom of the visible settings worked like a charm.
So, I've been happy with the performance of the optic. However, was it durable during my testing?
Every Day Carry
I carry a gun daily. Yeah, shocking news. However, I really do mean daily, and I mean all day. From when I'm up in the morning, till I go to sleep, I'm armed. During the last year, the 48 has been one of three primary guns that I've carried daily, and at this point, is the one with the most hours on my person. I covered this in my EDC update over this Summer, but regardless of being in regular clothing, or at the gym, that 48 has been on me. By extension, the RMRcc has been along for the ride too.
I've had no failures whatsoever on the RMRcc. It has never died, had reticle flickering, or any sort of breakages. I've got a couple of small dents in the housing due to bumping into things, however, nothing that has really hurt the optic. At time of writing, I'm at about 8000 rounds of 9mm through the G48. This includes the NPE Counter Robbery course in April of 2023, and Tests & Standards in July 2023. With shooting use and the G-forces applied to the optic, I'm quite happy with this.
Now, I have swapped my battery twice now. The "three year" battery life is optimistic. However, I've been quite happy with the battery life. From November 2022 till April 2023, I had the RMRcc at max brightness 95% of the time. I have very good vision, and when using a white light or shooting in harsh sunlight, I like a bright, large dot. As such, my battery life was only about 6 months. Now, the optic didn't just die, it just stepped down to the second highest setting, and stayed strong there. I later swapped the battery again in July 2023, as I swapped all of my RMR batteries on the 4th of July.
The highest brightness setting on the RMRcc is extremely bright. Like, one of the brightest settings I've seen on any optic. I like that, however, it does impact battery life. On the second highest setting, the reticle is still very bright, but the battery lifespan is more expanded. The blue notch filter tint really allows that second setting to work well in most conditions. Would it be better if the battery compartment didn't require removing the optic to swap? Totally, but I'm used to this design, and don't find it the hurt my use of the optic.
Why Choose the RMRcc?
The RMR was my first foray into the MRDS scene. My first RDS handgun was a VP9 that I had ATEi mill for me back in 2019. As time went on, and I used the RMR more and more, I found myself liking it more and more. While there are some parts I don't like (really just the battery location), I've generally got no qualms with the RMR. From the clarity of the reticle, the blue notch filter helping with contrast, the common footprint, and the ubiquitous durability, the RMR has been my preferred MRDS. When it came time to get an optic for the G48, the RMRcc was a simple choice for me.
While there are a ton of great compact MRDS out there, the RMRcc just ticks more boxes for me. Durability is extremely important for me, as I'm using my firearm daily, and shooting a ton. While I've generally had good experiences with the common Holosun K series, I've also gotten a defective 507K in the past. I've yet to have a defective Trijicon RMR, and I've owned a half dozen of them over the last decade. I've got a Type 1 RM06 with close to 25,000 rounds of 9mm on it, and it's still going strong too.
This isn't meant to rag on Holosun, as they generally make great optics. However, I trust Trijicon more due to years of perfect service with their optics. While I could have saved a good chunk of money and gotten the 407/507K, the RMRcc is something that I'm glad I ponied up the extra cash for. Now, I'm not a Trijicon fanboy, as the SRO is an optic that I despise, and the ACOG is something that I really dislike. The RMR series (barring the dual-illuminated) is the best thing Trijicon makes, and the RMRcc falls right in line.
In my year of use, the RMRcc has been fantastic. Aside from the need for a battery change at a faster interval, I'm ecstatic with this optic. It's an RMR, but smaller. Now, would I recommend it? Certainly! It's about the same price as an RMR, with about the same performance as one too.
Now, how does it stack up against other options on the market? Well, it's certainly better than the SIG & RMSc optics that exist. In regards to the Holosun micro series, I think that the RMRcc is better made. Between the higher QC, and better durability, I prefer the RMRcc. However, the 407/507K, and newer EPS are quality optics. The biggest decision for most people is going to be handgun related. Since the RMRcc uses it's own footprint, it cannot fit on popular pistols, like the 43X/48MOS without an adapter. The Holosun's direct mount, which is a big selling point.
I went out of my way to mill my Glock 48 for the RMRcc, and I'm glad that I did so. However, this was considerably more expensive to do, rather than to get an MOS gun, and a Holosun to mount. I'm happy that I did so though. If you want an RMR, but tinier, the RMRcc is there for you.
