Let’s Dive into Trijicon RM63 RMR Mount Sealing Plate
The Trijicon RM63 RMR Mount Sealing Plate is a small but vital component designed to protect your investment. Manufactured by Trijicon, this stainless steel plate creates a waterproof seal for your RMR (Ruggedized Miniature Reflex) sight when mounted on a pistol slide, specifically when a direct milling solution is used. The plate prevents moisture and debris from entering the battery compartment, ensuring reliable performance in harsh environments.
My journey to acquiring the Trijicon RM63 RMR Mount Sealing Plate began after I had my Glock 19 slide milled for a direct RMR mount. While the direct mount offered a lower profile and enhanced co-witnessing with my iron sights, it created a gap exposing the RMR’s battery compartment – a vulnerability I couldn’t ignore, knowing my Glock would be exposed to the elements, as I use it both for everyday carry and backcountry excursions.
Upon receiving the Trijicon RM63 RMR Mount Sealing Plate, I was immediately impressed by its simple yet robust design. The matte black finish of the stainless steel plate blended seamlessly with my RMR and Glock slide, and the plate felt solid and well-machined, inspiring confidence in its ability to withstand the rigors of daily carry and demanding environments.
While several aftermarket sealing plates are available, I opted for the Trijicon RM63 RMR Mount Sealing Plate due to Trijicon’s reputation for quality and reliability. I considered a few universal sealing plates, but I felt the Trijicon offered the best and most precise fit for my specific RMR.
Initially, I was relieved and satisfied; the exposed battery compartment was now protected from the elements and the overall fit and finish gave me the confidence I needed to use my pistol in adverse conditions. It’s a small piece, but its importance to the overall reliability of my RMR setup cannot be overstated.
Real-World Testing: Putting Trijicon RM63 RMR Mount Sealing Plate to the Test
First Use Experience
I first tested the Trijicon RM63 RMR Mount Sealing Plate at an outdoor shooting range during a particularly wet and muddy day. The plate was subjected to rain, mud splatters, and general grime from handling the firearm. Despite these conditions, the RMR’s optic remained clear and functional, demonstrating the plate’s ability to effectively seal out moisture.
The Trijicon RM63 RMR Mount Sealing Plate proved easy to install. Once installed, I could confirm that the plate provided peace of mind without hindering the RMR’s operation.
Extended Use & Reliability
After several months of consistent use, including daily carry and multiple range trips, the Trijicon RM63 RMR Mount Sealing Plate has held up remarkably well. There are no visible signs of wear or corrosion. The plate continues to provide a reliable seal against moisture and debris.
Maintaining the Trijicon RM63 RMR Mount Sealing Plate is incredibly simple. Regular cleaning of the pistol is all that’s required to keep the plate in good condition. This experience significantly outperforms previous setups where I lacked a sealing plate and had to regularly clean and dry the RMR’s battery compartment.
