The Story of My Time with the Evolution Gun Works Trijicon RMR Sight Mount
My quest for a more streamlined sight setup on a few of my handguns led me directly to the Evolution Gun Works Trijicon RMR Sight Mount. For years, I’d been sticking with iron sights, but as my proficiency grew, so did my curiosity about red-dot optics. The problem was integrating them without costly slide milling or extensive modification, especially on firearms where I wanted to retain the option of quickly reverting to iron sights. This particular mount promised a direct swap for the rear sight dovetail, which sounded like a brilliant, non-permanent solution.
The product description immediately caught my eye with its simple premise: replace your rear sight with this mount, and you’re ready for a Trijicon RMR or compatible optic. It sounded almost too good to be true. My initial impression upon unboxing was positive; the mount felt solid, well-machined, and the 7075 Aluminum construction hinted at durability without adding significant weight. I had briefly considered other solutions, like universal plates that clamp onto Picatinny rails, but those often add bulk and height, and many require specific slide cuts. This EGW mount, however, offered a more integrated and elegant approach. A sense of practical optimism washed over me – this felt like the right piece of the puzzle.
Real-World Testing: Putting Evolution Gun Works Trijicon RMR Sight Mount to the Test
First Use Experience
My initial testing grounds were my usual range days, specifically focusing on a couple of polymer-framed pistols that didn’t come with factory optic cuts. The installation process was straightforward: remove the existing rear sight, slide the EGW mount into the dovetail, and secure it. On one pistol, it drifted in with minimal persuasion; on another, it required a gentle tap from a nylon punch, a common occurrence with dovetail installations. The key here was the ease of this swap. Within minutes, I had transformed a standard pistol into a red-dot-ready platform.
I mounted a Trijicon RMR and a Holosun 507C onto the respective mounts. The fit was snug, and the included mounting screws, when torqued correctly to the recommended 15 inch-pounds, felt secure. I made a point of testing in conditions that mimicked a busy day at the range: rapid fire drills, some exposure to dust kicked up from the firing line, and even a light misting from an unexpectedly sprung water cooler. The mount held firm, and critically, the red-dot sights themselves maintained their zero through all of it. The paper trick mentioned in the instructions for easier RMR removal proved surprisingly useful, preventing accidental Loctite bonding to the optic itself.
Extended Use & Reliability
After several months of consistent use across various training classes and casual range visits, the Evolution Gun Works Trijicon RMR Sight Mount has proven to be remarkably reliable. I’ve put hundreds of rounds through firearms equipped with these mounts, and there has been no discernible shift in zero. The 7075 Aluminum shows only minor cosmetic scuffs from being handled and sometimes placed on rough surfaces, but its structural integrity remains completely uncompromised.
Cleaning is as simple as cleaning the rest of the firearm. A quick wipe-down with a solvent and a soft cloth is all that’s needed. There are no complex mechanisms to worry about, and because it replaces a solid rear sight, its durability is directly tied to the dovetail it occupies. Compared to other solutions I’ve used in the past – cheap universal plates that flex or proprietary mounting systems with finicky screws – this EGW offering is a breath of fresh air in terms of longevity and consistent performance. The ability to uninstall it and re-install the original rear sight in under five minutes is also a major plus for firearms that see dual-duty.
Breaking Down the Features of Evolution Gun Works Trijicon RMR Sight Mount
Specifications
The Evolution Gun Works Trijicon RMR Sight Mount is precisely engineered for its intended purpose. Its core material is 7075 Aluminum, a robust alloy known for its high strength-to-weight ratio, making it ideal for firearm accessories that need to be both durable and lightweight. The mount utilizes a Dovetail Mount Type, designed to fit snugly into the existing rear sight dovetail cut on compatible firearms. This specific optic cut is for the Trijicon RMR, Trijicon SRO, and other optics with the same footprint, ensuring a secure interface.
The mount comes with essential Included Accessories, namely 2 6-32 Flat Head Screws for attaching the red-dot sight to the mount. Installation instructions explicitly state the need to torque these screws to 15 inch-pounds, a critical step for ensuring optic retention and preventing damage. The screws themselves require a 5/64 inch Allen wrench for tightening, a common size for optics mounting. The product also specifies compatibility for specific firearm models, such as the MPN:49503 for Desert Eagle Pre-2017 and MPN:49501 for Baby Desert Eagle Post-2006, highlighting the importance of selecting the correct version for your firearm.
Performance & Functionality
The primary function of the Evolution Gun Works Trijicon RMR Sight Mount is to provide a stable, reliable platform for mounting a red-dot sight where a standard rear sight would normally reside. In this regard, it performs exceptionally well. The secure dovetail fit, combined with the proper torquing of the optic’s mounting screws, results in a solid platform that resists recoil and vibration. I experienced no “walking” of the zero, even after hundreds of rounds fired on various platforms.
Its strength lies in its simplicity and directness. It doesn’t add unnecessary complexity or height beyond what’s needed to interface with the RMR footprint. The slight setback of the optic is generally manageable for most shooters, often allowing for a usable co-witness with suppressor-height iron sights if you retain them (though the design implies replacing the rear sight entirely). The main drawback, inherent to any rear-sight-replacement mount, is the loss of the traditional iron sight sighting plane unless auxiliary sights are added. However, for its intended use as a dedicated red-dot mount, its functionality is superb.
Design & Ergonomics
The design of the Evolution Gun Works Trijicon RMR Sight Mount is functional and utilitarian. Machined from 7075 Aluminum, it feels solid and precise. The finish is typically a matte black anodizing that blends well with most firearm finishes. Ergonomically, it’s designed to be a direct replacement, so there are no grip surfaces or controls to interact with on the mount itself. Its profile is low, minimizing the added bulk to the firearm.
The precision of the machining is evident; the dovetail is cut to tight tolerances, ensuring a secure fit without excessive force. The recess for the optic is clean and well-defined, preventing any wobble or misalignment. The inclusion of a set screw on some variations (though not explicitly detailed for all models, it’s often a feature) can add an extra layer of security against movement, particularly in high-recoil applications. While not aesthetically flashy, its design prioritizes function and reliability, which is precisely what one looks for in a component like this.
Durability & Maintenance
Given its construction from 7075 Aluminum and its simple, solid design, the Evolution Gun Works Trijicon RMR Sight Mount is built for longevity. Under normal use and proper installation, it’s a component that should outlast many firearms it’s mounted on. The anodized finish offers good scratch resistance, though like any firearm accessory, it can show wear if subjected to abuse.
Maintenance is virtually non-existent. Beyond occasional cleaning to remove carbon fouling or debris that might find its way into the optic’s mounting area, there’s little to do. The critical factor for durability is correct installation, particularly the torque specification for the optic’s mounting screws. Over-tightening can strip threads or damage the optic, while under-tightening can lead to zero loss. The set screw, if present, should also be checked for tightness periodically. I haven’t encountered any failure points, and the design is inherently robust, making it a very low-maintenance accessory.
Accessories and Customization Options
The Evolution Gun Works Trijicon RMR Sight Mount comes with the essential hardware needed for its direct application: 2 6-32 Flat Head Screws for attaching the red-dot sight. The primary “customization” aspect comes from selecting the correct mount for your specific firearm model and the choice of optic itself. EGW offers variations of this mount for different pistols and optics patterns, so ensuring you have the correct part number for your firearm’s dovetail is crucial.
While the mount itself isn’t customizable, its purpose is to enable customization of the firearm’s sighting system by allowing the use of various red-dot sights. For those who still desire iron sights, the use of suppressor-height sights can often allow for a lower-third co-witness through the RMR window, though this depends on the specific firearm and optic used. The ability to easily remove the mount and reinstall a standard rear sight provides a level of modularity that is highly valued.
