Trijicon RMRcc Lower 1/3 Co-Witness Mount w/Q-LOC Technology Review

First Impressions of Trijicon RMRcc Lower 1/3 Co-Witness Mount w/Q-LOC Technology

The Trijicon RMRcc Lower 1/3 Co-Witness Mount w/Q-LOC Technology promises a robust and reliable mounting solution for the popular RMRcc red dot sight. As someone who’s spent countless hours tweaking and perfecting optic setups, I was eager to see if this mount lived up to the Trijicon name, known for its unwavering quality and durability. The promise of a quick-release system, combined with a lower 1/3 co-witness, immediately piqued my interest, suggesting a blend of tactical efficiency and practical functionality.

My journey to find the perfect RMRcc mount began with frustration. I was struggling to find a mount that offered both a secure and repeatable zero, while also providing a usable co-witness with my iron sights. Other mounts felt flimsy or lacked the quick detach capability I desired for versatility.

Upon unboxing, the Trijicon RMRcc Lower 1/3 Co-Witness Mount immediately impressed me with its solid feel. The 6061-T6 aluminum construction felt incredibly sturdy, and the black finish was clean and professional. Compared to some cheaper mounts I’ve used in the past, this one felt like a serious piece of kit.

I considered mounts from Scalarworks and Midwest Industries, both reputable companies. However, I ultimately chose the Trijicon mount for its Q-LOC technology, which seemed to offer a more secure and user-friendly quick detach system. My initial impression was one of cautious optimism; I was excited to test its claims of rock-solid repeatability and ease of use.

Real-World Testing: Putting Trijicon RMRcc Lower 1/3 Co-Witness Mount w/Q-LOC Technology to the Test

First Use Experience

I first tested the Trijicon RMRcc Lower 1/3 Co-Witness Mount at my local outdoor range, mounting it on my AR-15 pistol chambered in 9mm. The weather was typical for early spring: cool, slightly damp, and with a persistent breeze. Installation was straightforward; the Q-LOC system allowed me to attach and detach the mount from the Picatinny rail in seconds, without any tools.

The lower 1/3 co-witness provided a clear sight picture, with my iron sights sitting neatly in the lower portion of the optic window. Even in the slightly overcast conditions, the RMRcc’s dot was easily visible. I did experience a slight shift in point of impact after the initial mounting, but after a quick re-zero, it held true for the rest of the session.

Extended Use & Reliability

After several weeks of regular use, including multiple range trips and a weekend training course, the Trijicon RMRcc Lower 1/3 Co-Witness Mount has proven to be incredibly reliable. There are no noticeable signs of wear and tear, despite repeated mounting and dismounting. Cleaning is simple; a quick wipe down with a microfiber cloth is usually all it takes.

Compared to my previous experience with a budget mount that constantly loosened and lost zero, the Trijicon mount is a game-changer. It consistently returns to zero after being removed and reattached, inspiring confidence in its performance. This mount has far exceeded my expectations.

Breaking Down the Features of Trijicon RMRcc Lower 1/3 Co-Witness Mount w/Q-LOC Technology

Specifications

• Manufacturer: Trijicon. Trijicon is a well known brand in the industry.
• Color: Black. The black color blends well with most firearms.
• Co-Witness: Lower 1/3. This provides a clear field of view while still allowing for backup iron sight use.
• Fabric/Material: 6061-T6 Aluminum. This provides a lightweight and durable platform.
• Optic Cut: Not Applicable. The mount is a standalone Picatinny mount.
• Red Dot Sights-Footprint: RMRcc. This is specifically designed for the smaller RMRcc.
• Housing/Frame Material: 6061-T6 aluminum. The material is durable.

These specifications contribute directly to the mount’s performance and user experience. The 6061-T6 aluminum ensures strength without adding unnecessary weight, while the lower 1/3 co-witness provides a practical balance between red dot visibility and iron sight accessibility. The Q-LOC system adds convenience and reliability.

Performance & Functionality

The Trijicon RMRcc Lower 1/3 Co-Witness Mount performs its job exceptionally well. The red dot sits securely and remains zeroed even after repeated removal and reattachment. Its strength lies in the Q-LOC system, which provides a fast, tool-less, and repeatable mounting solution.

While the mount is excellent overall, the one area for potential improvement might be the height. Some users with specific iron sight configurations might find the lower 1/3 co-witness to be slightly too high or too low, although that is subjective. However, the mount meets and exceeds my expectations.

Design & Ergonomics

The mount’s design is clean, functional, and unobtrusive. The 6061-T6 aluminum construction feels robust, and the weight is minimal, adding almost nothing to the overall weight of the firearm. The rounded edges prevent snagging on gear or clothing, enhancing comfort during use.

The mount is incredibly user-friendly, requiring no specialized knowledge or tools for installation or removal. The Q-LOC lever is easy to manipulate, even with gloved hands. The learning curve is non-existent.

Durability & Maintenance

Given its 6061-T6 aluminum construction and the Trijicon name, I expect this mount to last for many years. The simple design minimizes potential failure points, and the black finish is resistant to scratches and corrosion. Maintenance is minimal, requiring only occasional cleaning.

Accessories and Customization Options

The Trijicon RMRcc Lower 1/3 Co-Witness Mount itself doesn’t come with any accessories beyond the necessary hardware for attaching the RMRcc. However, its compatibility with any Picatinny rail opens up a wide range of customization options. Of course, it requires an RMRcc red dot sight, but other than that, it’s largely self-contained.
