Leapers UTG Pro Super Slim RMR 45 Degree Angle Mount Review

How I Used the Leapers UTG Pro Super Slim RMR 45 Degree Angle Mount and What I Found

As someone who has spent over a decade navigating the intricacies of gear across diverse environments – from the demanding ruggedness of the outdoors to the precise requirements of a lab and the unforgiving nature of field work – I’ve developed a keen eye for what truly performs. The Leapers UTG Pro Super Slim RMR 45 Degree Angle Mount landed on my bench with a reputation for being an accessible, budget-friendly option for adding a red dot optic to a firearm. My interest was piqued by its promise of a low-profile, durable solution for secondary aiming devices, particularly in conjunction with LPVOs (Low Power Variable Optics). The scenario that prompted this investigation was a desire to streamline my rifle setup, specifically aiming to integrate a backup red dot sight without adding excessive bulk or compromising my primary optic’s field of view. I had been looking for a way to achieve a quick transition from magnified to unmagnified sighting, a common need for tactical and competitive shooting scenarios. Initial impressions revealed a surprisingly robust construction for its price point, machined from aircraft-grade aluminum with a matte black anodized finish. While I considered a few other, more expensive options, their bulk and higher cost made them less appealing for this particular application. My first reaction was a sense of cautious optimism; could this affordable mount truly deliver on its promises of secure zero hold and user-friendly integration?

Real-World Testing: Putting **Leapers UTG Pro Super Slim RMR 45 Degree Angle Mount** to the Test

First Use Experience

I put the Leapers UTG Pro Super Slim RMR 45 Degree Angle Mount through its paces on my primary training rifle, a platform I regularly use for dynamic shooting drills and extended range sessions. Testing involved mounting it to a standard Picatinny rail system, attaching a Trijicon RMR footprint optic, and cycling through various shooting positions and transitions. The mount performed admirably under typical range conditions, demonstrating a solid connection to the rail with its Torx locking screw. Initially, the installation was straightforward, with the included hardware making the process relatively intuitive.

However, a slight quirk emerged during the initial setup. While the mounting holes for the RMR were precisely machined, I encountered a minor fitment issue with my specific rifle’s accessory rail. This necessitated a slight modification by grinding down one of the rail slots to achieve a perfect, wobble-free engagement. This is not necessarily a fault of the mount itself, but rather a testament to the inherent variations in rail manufacturing tolerances across different firearm platforms. Despite this minor adjustment, the mount secured the optic with impressive stability, and the height placement was, frankly, perfect for co-witnessing over a weapon-mounted light.

Extended Use & Reliability

After several hundred rounds and countless transitions between my LPVO and the secondary RMR, the Leapers UTG Pro Super Slim RMR 45 Degree Angle Mount has held up remarkably well. There have been no discernible shifts in zero, and the mount remains firmly attached to the rifle. The matte black anodized finish shows only the faintest signs of handling marks, a testament to its durability under regular use. Cleaning and maintenance are as simple as wiping down the firearm; there are no complex mechanisms to worry about, and the aluminum construction resists corrosion.

Compared to previous experiences with similar, albeit often more expensive, offset mounts, this UTG Pro model has been a pleasant surprise. It hasn’t exhibited the loosening issues that some budget alternatives can develop over time, nor does it feel overly heavy or bulky, which is a critical consideration for a super slim design. It has proven to be a reliable workhorse, performing its intended function without complaint, which is precisely what one hopes for in a piece of equipment that needs to be dependable under pressure.

Breaking Down the Features of **Leapers UTG Pro Super Slim RMR 45 Degree Angle Mount**

Specifications

The Leapers UTG Pro Super Slim RMR 45 Degree Angle Mount is meticulously machined from 6061-T6 Aircraft Aluminum, a material renowned for its excellent strength-to-weight ratio and corrosion resistance. This construction ensures durability without adding unnecessary mass to your firearm setup. The mount features a Matte Black Anodization, providing a non-reflective finish that is both aesthetically pleasing and resistant to scratches and environmental wear. Its overall dimensions are 1.78 inches in length and 1.02 inches in height, contributing to its “super slim” profile which is crucial for maintaining a low optical axis.

Weighing in at a mere 1.4 oz, this mount is exceptionally lightweight, a significant advantage for firearms where every ounce counts. The attachment method is a standard Picatinny mount, ensuring compatibility with a wide range of modern rifle platforms. Crucially, it is designed to accommodate the RMR footprint, making it ideal for a variety of popular red dot sights. The low profile Torx locking screw base, coupled with squared recoil stops, is a key feature designed to provide a secure zero hold, resisting the impact of recoil that can often dislodge lesser mounts. The product comes as a New unit, ready for immediate installation.

Performance & Functionality

The primary function of this offset mount is to provide a stable and correctly positioned platform for an RMR-style red dot sight, allowing for rapid secondary sighting. In this regard, the Leapers UTG Pro Super Slim RMR 45 Degree Angle Mount performs exceptionally well. The mounting interface for the RMR itself is precise, and the engagement with the Picatinny rail is solid, thanks to the Torx screw and recoil stops. This secure fit means that once zeroed, the optic stays put, even after hundreds of rounds downrange.

The ideal positioning it offers is a major strength. It sits the RMR at a height that is perfectly usable as a backup to a magnified optic, clearing the objective bell of an LPVO without raising it to an uncomfortable or unwieldy level. The transition from your primary optic to the RMR is smooth and almost instinctual, which is paramount in dynamic shooting situations. While the mount itself doesn’t have inherent “weaknesses” in its core function, its success is also dependent on the optic it holds; a poorly made RMR will still perform poorly, regardless of the mount. However, for its intended purpose, it functions flawlessly.

Design & Ergonomics

The design of the Leapers UTG Pro Super Slim RMR 45 Degree Angle Mount emphasizes minimalism and efficiency. The use of significant lightening cuts is evident throughout its construction, reducing bulk and contributing to its featherlight weight. This attention to detail in its design not only enhances its tactical appeal but also ensures it won’t negatively impact the balance of your firearm. The matte black anodized finish is not only practical for reducing glare but also feels smooth and professional to the touch, indicating a decent level of finishing for its price.

Ergonomically, the mount is unobtrusive. Its low profile means it rarely interferes with hand placement or charging handles, which is a common issue with bulkier accessories. The Torx screw head for securing it to the rail is accessible, and the included installation tools make the process straightforward. While there’s no complex “ergonomic grip” to speak of, the smooth, clean lines and lack of sharp edges contribute to a positive user experience during installation and subsequent handling.

Durability & Maintenance

Durability is clearly a focus for this mount. The 6061-T6 Aircraft Aluminum is a solid choice for a component subjected to the stresses of recoil and environmental exposure. After extensive use, I’ve observed no signs of cracking, deformation, or structural compromise. The anodized finish has proven to be resilient, resisting minor abrasions and typical handling that would mar lesser coatings.

Maintenance is virtually non-existent. A quick wipe-down with a clean cloth is all that’s typically needed to keep it looking and functioning its best. The internal components of the mount are minimal, reducing potential failure points. The only maintenance concern would be ensuring the Torx screw remains tight; however, the squared recoil stops significantly aid in maintaining zero, reducing the need for constant re-tightening. For its intended use as a durable, long-lasting component on a firearm, this mount appears built to last.

Accessories and Customization Options

The Leapers UTG Pro Super Slim RMR 45 Degree Angle Mount comes with a thoughtful selection of included items to facilitate installation. Notably, it includes RMR® Mounting Screws specifically designed for attaching your red dot optic to the mount. Furthermore, it also comes with Installation Tools, which is a significant plus for a budget-oriented accessory, ensuring you have everything you need right out of the box.

While the mount itself isn’t highly “customizable” in terms of altering its core design, its compatibility with the RMR footprint is a major advantage. This allows users to select from a wide array of RMR-style red dot sights from various manufacturers, including Trijicon, Holosun, and others that share the footprint. The Picatinny attachment also ensures it integrates seamlessly with most standard rifle rail systems. The key “customization” here lies in the optic you choose to pair with this solid mounting base.
