First Thoughts on the MNT SHTGN RIB UNIV RMR
The MNT SHTGN RIB UNIV RMR promises to be a game-changer for shotgun enthusiasts looking to modernize their aiming solutions. Red dot sights have become increasingly popular on pistols and rifles, but shotguns have often been left behind due to mounting challenges. This mount, designed by an unknown manufacturer but clearly aiming for broad appeal, attempts to bridge that gap by offering a universal solution for attaching an RMR-pattern optic to a shotgun rib. For a price of $34.49, it sits within the budget-friendly category, which immediately sparks questions about build quality and overall effectiveness.
I’ve always been a proponent of improved accuracy, and the ability to quickly acquire targets is crucial in dynamic shooting scenarios. My need for this product stemmed from a desire to enhance the versatility of my trusty 12-gauge for both hunting and defensive applications. I was seeking a stable and low-profile mounting solution for my RMR without requiring permanent modifications to my shotgun.
Upon unboxing, the MNT SHTGN RIB UNIV RMR appeared surprisingly compact and lightweight. The black finish seemed durable enough, though I initially questioned how well it would hold up to repeated recoil. The design looked relatively straightforward, implying an easy installation process, but the lack of any immediately apparent instructions was a minor cause for concern.
Compared to other potential solutions like saddle mounts or gunsmith-installed rails, the MNT SHTGN RIB UNIV RMR offered a non-permanent, significantly cheaper alternative. I chose it specifically for its promised universality and ease of installation, hoping to avoid the expense and potential damage associated with professional gunsmithing. My first impression was cautiously optimistic; the low price point made me slightly skeptical, but the design seemed promising.
Real-World Testing: Putting MNT SHTGN RIB UNIV RMR to the Test
First Use Experience
My initial testing of the MNT SHTGN RIB UNIV RMR took place at my local shooting range, utilizing a variety of shotgun loads ranging from light target rounds to heavier buckshot. I mounted it on my Benelli Nova, carefully following the instructions I found online after the initial packaging lacked any. The first few shots with light target loads felt stable, and the RMR held zero reasonably well.
However, the situation quickly deteriorated with heavier loads. After only a handful of buckshot rounds, the mount began to loosen, requiring frequent re-tightening. The intense recoil of the 12-gauge proved to be a significant challenge for the mounting system, even though I tightened it to what felt like the reasonable maximum.
Ease of use was initially high, installation was relatively simple. The loosening, however, drastically reduced the ease of use. The biggest surprise was how quickly the recoil impacted the mount’s ability to stay secure.
Extended Use & Reliability
After several weeks of use and multiple range sessions, the MNT SHTGN RIB UNIV RMR showed noticeable signs of wear. The finish began to chip around the mounting screws, and the screws themselves started to show signs of stripping, despite careful tightening. Durability was a major concern.
The mount requires constant monitoring and re-tightening, making it unreliable for any serious application. Cleaning was straightforward enough, simply wiping down the mount after each range session. The mount did not live up to my expectations based on other mounting solutions.
Breaking Down the Features of MNT SHTGN RIB UNIV RMR
Specifications
The MNT SHTGN RIB UNIV RMR is designed as a universal mount, intended to attach any RMR footprint red dot sight to the rib of a shotgun. It boasts a base that adapts to the RMR pattern footprint. The product information makes no mention of specific materials or gauges of shotguns it is specifically suited for. This lack of clear specification is a significant drawback.
The fact that it is supposed to be ‘universal’ is a double edged sword. It suggests broad compatibility, but also implies compromises in fit and stability compared to a mount designed for a specific shotgun model.
Performance & Functionality
The mount’s primary function is to provide a stable platform for an RMR optic on a shotgun. In theory, the MNT SHTGN RIB UNIV RMR facilitates faster target acquisition and improved accuracy, particularly in dynamic shooting scenarios. Unfortunately, the mount’s tendency to loosen under recoil significantly undermines its effectiveness.
Its biggest weakness is its inability to maintain a secure hold on the shotgun rib, especially with heavier loads. While it initially positions the optic, the constant need for adjustment renders it unreliable. It falls short of expectations, as a reliable mount is paramount for any serious application.
Design & Ergonomics
The MNT SHTGN RIB UNIV RMR features a low-profile design that keeps the optic close to the bore axis. This is generally beneficial for maintaining a natural cheek weld and sight picture. The build quality, however, feels somewhat lacking.
The materials used appear to be inexpensive, and the overall construction doesn’t inspire confidence. There is a slight learning curve, initially figuring out optimal placement, but once mounted, the optic sits well.
Durability & Maintenance
Given its performance in testing, the long-term durability of the MNT SHTGN RIB UNIV RMR is questionable. The screws are prone to stripping, and the finish wears easily. Maintenance is minimal, requiring only occasional cleaning.
However, its inherent instability means that regular disassembly and re-tightening are almost guaranteed, leading to accelerated wear and tear. The low initial cost is offset by its likely short lifespan.
Accessories and Customization Options
The MNT SHTGN RIB UNIV RMR doesn’t come with any additional accessories beyond the mounting hardware itself. The only customization option is the choice of RMR-pattern optic to install. While it should theoretically be compatible with any RMR footprint optic, its universal design doesn’t cater to any specific brand or model.
Pros and Cons of MNT SHTGN RIB UNIV RMR
Pros
- Low Price point.
- Easy Initial Installation.
- Low Profile Design.
Cons
- Unreliable under Recoil.
- Poor Durability.
- Limited Customization.
Who Should Buy MNT SHTGN RIB UNIV RMR?
The MNT SHTGN RIB UNIV RMR might be suitable for casual shooters using light target loads and seeking an extremely inexpensive way to experiment with red dot sights on their shotguns. It may also be useful for someone needing a temporary solution before investing in a higher quality mount.
This is not for hunters, tactical shooters, or anyone relying on their shotgun for self-defense. Anyone needing a durable and reliable mount should skip this product. A threadlocker would be a must-have accessory.
Conclusion on MNT SHTGN RIB UNIV RMR
The MNT SHTGN RIB UNIV RMR promises a lot but ultimately falls short in delivering a reliable and durable mounting solution for RMR optics on shotguns. While the low price is attractive, the mount’s inability to withstand recoil and its questionable build quality make it a poor investment for serious shooters. The price is not justified given its performance issues.
I would not personally recommend this product for anyone seeking a dependable optic mounting solution. The constant need for adjustment and the risk of failure outweigh the initial cost savings. Save your money and invest in a higher-quality mount for reliable performance and peace of mind.
