First Thoughts on the RMR Dovetail Mount For Glock
The RMR Dovetail Mount For Glock promises a simple and effective way to add a red dot optic to your Glock without the need for expensive slide milling. This inexpensive mount from an unknown manufacturer replaces the rear sight, providing a platform for mounting an RMR-pattern red dot sight. I was intrigued by the potential of this product, specifically its affordability and ease of installation.
My aging eyes needed a boost, and I was struggling with iron sights on my Glock 19. I wanted to explore the red dot world without permanently altering my firearm. Several options exist, including complete slide replacements and having a gunsmith mill my existing slide. These were either too expensive or time-consuming. I was looking for an affordable and easily reversible solution. The RMR Dovetail Mount For Glock seemed to fit the bill perfectly.
Upon receiving the mount, my first impression was a mix of curiosity and skepticism. The mount itself is a small piece of metal, seemingly made of steel, coated in a black finish. The weight was negligible. Build quality seemed adequate for the price point. Compared to a milled slide or a dedicated RMR-cut slide, it felt less robust, but that was expected. Other options I considered were the Strike Industries RMR mount and the Dueck Defense RMR mount. The Strike Industries option had mixed reviews regarding its durability, while the Dueck Defense was significantly more expensive.
My initial feeling was cautiously optimistic. While the RMR Dovetail Mount For Glock didn’t exude premium quality, the simple design and low price made it a worthwhile gamble to try out a red dot on my Glock. I was excited to see if it could provide a stable and reliable platform for my RMR without breaking the bank.
Real-World Testing: Putting RMR Dovetail Mount For Glock to the Test
First Use Experience
I tested the RMR Dovetail Mount For Glock at my local indoor shooting range. Installation was straightforward, requiring only a Glock sight pusher tool. I replaced the factory rear sight with the mount and secured it tightly. I then mounted my Trijicon RMR to the mount using the provided screws. The entire process took less than 15 minutes.
I shot approximately 200 rounds of 9mm through my Glock 19 with the RMR mounted using this system. Initially, the mount seemed secure, and the RMR held zero reasonably well. However, after about 100 rounds, I noticed a slight shift in the point of impact. Closer inspection revealed that the mount was beginning to loosen within the dovetail. Recoil was definitely a factor. This was disappointing, but not entirely unexpected given the price point.
Extended Use & Reliability
After several weeks of use and approximately 500 rounds fired, the RMR Dovetail Mount For Glock continued to loosen after each range session. I tried various methods to secure it, including using thread locker on the dovetail and RMR mounting screws. While these helped temporarily, the mount would still eventually work its way loose.
The black finish showed minimal wear and tear, but the constant re-tightening of the screws started to damage the screw heads. Maintaining the mount required frequent checks to ensure it was secure. This became tedious and ultimately made me question its reliability for serious use. Compared to my experience with a milled slide on another pistol, the RMR Dovetail Mount For Glock was significantly less reliable and required constant attention.
Breaking Down the Features of RMR Dovetail Mount For Glock
Specifications
The RMR Dovetail Mount For Glock is designed to fit Glock pistols that utilize a standard rear sight dovetail. The mount is designed to accept RMR-pattern red dot sights.
The mount is constructed from what appears to be steel with a black finish. Its weight is negligible, adding minimal bulk to the pistol. The mounting screws for the RMR are included.
The use of steel should theoretically provide adequate strength. However, the method of attachment (dovetail only) is inherently less stable than a milled slide. The black finish is purely cosmetic and offers minimal protection.
Performance & Functionality
The RMR Dovetail Mount For Glock performs its primary function – providing a mounting platform for an RMR – but with caveats. Its biggest weakness is its tendency to loosen over time due to recoil. This impacts accuracy and reliability.
The mount’s simplicity is its greatest strength. Installation is quick and easy, and it allows users to experiment with red dot sights without permanent modifications. However, the lack of a robust locking mechanism or recoil lug makes it unsuitable for high-volume shooting or duty use. It ultimately falls short of expectations for a truly reliable RMR mounting solution.
Design & Ergonomics
The design is minimalist and functional. The low profile of the mount helps to minimize the overall height of the RMR setup. It’s difficult to tell the metal type.
The low profile is a benefit, but the mount’s tendency to loosen outweighs this advantage. The lack of any ergonomic considerations makes it purely a functional piece. There is no learning curve to using it.
Durability & Maintenance
The RMR Dovetail Mount For Glock‘s durability is questionable in the long term. The metal seems sturdy enough, but the loosening issue compromises its overall lifespan. Expect to replace it if you shoot frequently.
Maintenance involves regularly checking and tightening the mounting screws. The finish is easy to clean, but the damaged screw heads will eventually need replacement. It’s not designed for repair beyond simple screw replacements.
Accessories and Customization Options
The RMR Dovetail Mount For Glock comes with the necessary screws for mounting an RMR optic. There are no other included accessories. No customization options exist for the mount itself.
It is only compatible with RMR-pattern red dot sights. Due to its simple design, there are no aftermarket accessories designed specifically for it.
Pros and Cons of RMR Dovetail Mount For Glock
Pros
- Affordable entry point to RMR optics on Glocks.
- Easy and quick installation.
- No permanent modifications to the pistol required.

Who Should Buy RMR Dovetail Mount For Glock?
The RMR Dovetail Mount For Glock is perfect for budget-conscious shooters who want to experiment with red dot sights on their Glock without committing to expensive slide milling or replacement. It’s suitable for occasional range use and getting a feel for RMR optics.
This product should be skipped by anyone who requires a reliable and durable RMR mounting solution for serious use, such as duty carry or competitive shooting. Those shooters would be better served by a milled slide or a higher-quality mounting system.
A must-have accessory is a high-quality thread locker. A Glock sight pusher tool is also required for installation.
Conclusion on RMR Dovetail Mount For Glock
The RMR Dovetail Mount For Glock offers an inexpensive and easy way to try out a red dot sight on your Glock. However, its tendency to loosen under recoil compromises its reliability and makes it unsuitable for serious use.
The price is certainly justified for what it is – a temporary solution for experimenting with RMR optics. But be prepared to upgrade to a more robust mounting system if you decide to stick with a red dot sight.
I would only recommend it with strong reservations. It’s a good starting point, but not a long-term solution. If you’re curious about RMR optics, give it a try, but be prepared to invest in a better solution down the road. Consider the RMR Dovetail Mount For Glock as a stepping stone, not a destination.
