Optics Mounting & Servicing

Like it or not, pistol optics are here and they’re here to stay. It wasn’t all that long ago that we had very limited choices in terms of pistol optics. One of the original pistol optics which paved the way for other companies to follow is Trijicon and their RMR. Trijicon as a company is widely known for producing some of the most robust optics in the industry and particularly for military and police options. Their ACOG prism optic has been used for decades now with great success and it’s actually one of my favorite optics the military has ever fielded despite having an annoyingly short eye relief requiring the optic to be set back considerably in order to be useable. But this article is about pistol optics specifically.

The Trijicon RMR was my very first pistol optic. Mine is the RM06 version with a 6MOA red dot, but now they have a bunch of different variants including green dot versions which I sure hope to get one of those to use someday soon. Brownells carries and sells the complete Trijicon catalog so next time I’ll look to them again for my Trijicon RMR. My Trijicon RMR has done everything that I’ve asked of it and more. It’s been beat around, dropped etc…and has always held zero. I have it mounted up on a very early Glock clone build I did using a Brownells exclusive Polymer 80 frame with a Grey Ghost Precision slide and barrel. This pistol shoots like an absolute dream with the Overwatch Precision trigger and Parker Mountain Machine compensator. Backup iron sights are also from Trijicon.


Since I’ve owned this since around 2018, what kind of maintenance and service have I had to do on this particular optic? Well it does use a CR2032 battery like many other optics do, but does require the removal of the optic to replace when needed. Since I do not use this pistol for defensive use, I typically wait for the battery to die and once it does, I break out my tools and replace it. If it was one a defensive pistol, then I would replace it pro action an annual schedule. Replacing the battery is very straightforward and with the help of my Brownells manga tip screwdriver set, I can remove the optic very easily. Re installing however is a bit more tricky as the screws should not be over tightened. When re installing the screws, I use my Wheeler FAT torque wrench to torque to 15inch pounds. Blue or purple Loctite is also recommended to keep the screws in place. Be sure to properly clean and de grease the screws before re installing. One other thing I like to do whenever I install an optic is to draw a witness line on each screw. This gives me the peace of mind that I can take a Quick Look to check that my optic screws are still tight and not loosened.

Pistol optics are a game changer in my opinion and totally change the shooting experience. If you haven’t tried one out by now, definitely do so! Just remember that you have to maintain them a little bit if you want them to work when you need them to.
