Let’s Dive into Trijicon RMR Dual Illuminated RM05 1×16 mm 9 MOA Reflex Sights
The Trijicon RMR Dual Illuminated RM05 1×16 mm 9 MOA Reflex Sights is a compact optic designed for rapid target acquisition on pistols and other small firearms. This red dot sight, manufactured by Trijicon, utilizes a combination of fiber optics and tritium for reticle illumination, ensuring a bright and clear aiming point in various lighting conditions without the need for batteries. I wanted a reliable, always-on optic for my carry pistol, and the RMR RM05 seemed like the perfect solution.
I was looking for something that didn’t rely on batteries, and the dual illumination system of the Trijicon RMR promised just that. Upon unboxing, the RMR felt incredibly robust. The forged aluminum housing exuded quality, and its compact size was immediately appealing.
I considered the Leupold DeltaPoint Pro and the Aimpoint Micro S-1, both excellent red dots. However, I ultimately chose the Trijicon RMR due to its reputation for durability and battery-free operation, critical for a defensive firearm. My first impression was one of cautious optimism. I was excited about the prospect of a reliable optic, but slightly apprehensive about potential washout issues in bright conditions, which I’d read about.
Real-World Testing: Putting Trijicon RMR Dual Illuminated RM05 1×16 mm 9 MOA Reflex Sights to the Test
First Use Experience
I first tested the Trijicon RMR at my local outdoor range. The weather was sunny with clear skies. Mounting the RMR on my Glock 19 was straightforward using a compatible adapter plate.
The 9 MOA dot was easy to acquire indoors and in shaded areas, providing a clear aiming point. However, as the user reviews suggested, I quickly noticed that the dot became difficult to see against bright targets in direct sunlight. While not completely washed out, it required conscious effort to locate the reticle.
The sight picture was clear and the adjustments for windage and elevation were precise and easy to make with a small screwdriver (thankfully, I brought one). After about 100 rounds, the sight remained securely mounted, and the zero held true.
Extended Use & Reliability
After several months of consistent use, the Trijicon RMR has proven to be a dependable optic. The forged aluminum housing shows no signs of wear, despite regular carry and occasional bumps. Cleaning the lens is simple. A quick wipe with a microfiber cloth removes any smudges or debris.
Compared to my previous experience with battery-powered red dots that required constant battery checks and occasional replacements, the RMR provides peace of mind. However, the washout issue in bright sunlight remains a limitation that I’ve learned to mitigate (more on that later). It is more of a consideration than a crippling defect.

Performance & Functionality
The Trijicon RMR Dual Illuminated RM05 1×16 mm 9 MOA Reflex Sights excels in rapid target acquisition, particularly in low-light conditions. The 9 MOA dot is large enough to be easily seen, yet small enough to provide reasonable accuracy at moderate distances.
The absence of an on/off switch is both a blessing and a curse. It’s always ready to go, but you can’t manually turn off the illumination. The dual illumination system is generally effective, but the dot can wash out in bright sunlight, requiring the shooter to adjust their aiming technique or shield the optic. While the RMR performs admirably in its intended role, the washout issue is a significant weakness.
The RMR meets expectations for durability and reliability but falls slightly short in terms of brightness in certain lighting conditions.
Design & Ergonomics
The build quality of the Trijicon RMR is exceptional. The forged aluminum housing feels incredibly solid, and the optic is surprisingly lightweight. The compact size minimizes bulk on a pistol slide.
The RMR is undeniably user-friendly. There are no buttons to press or settings to adjust. However, the lack of brightness control can be frustrating in bright conditions. The learning curve is minimal; simply mount it, zero it, and start shooting.
Durability & Maintenance
The forged aluminum construction and tempered glass lens suggest excellent longevity. The RMR is designed to withstand harsh conditions and heavy use. Maintenance is minimal, requiring only occasional cleaning of the lens.
The fact that it is waterproof to 66ft is reassuring, though I’ve not tested it to that depth.
Accessories and Customization Options
The Trijicon RMR Dual Illuminated RM05 1×16 mm 9 MOA Reflex Sights ships in a box, and includes basic mounting screws. A Picatinny rail adapter, various mounting plates for different pistol models, and protective shrouds are available separately. I added a Trijicon sealing plate to ensure a watertight seal between the optic and my slide. The RMR is compatible with many aftermarket iron sights designed for co-witnessing.
