First Thoughts on the Trijicon RMR Quick Release 1/3 Co-Witness Mount Black 1.80″
Red dot sights have revolutionized shooting for me, especially in fast-paced scenarios. After years of using various mounting solutions, I was still searching for the perfect blend of rock-solid stability, quick detach capability, and a comfortable co-witness height. Then, I found the Trijicon RMR Quick Release 1/3 Co-Witness Mount Black 1.80″.
My biggest issue was swapping optics between rifles; zero was never consistent after remounting. I needed a quick-release mount that would allow me to move my Trijicon RMR between different platforms without losing zero and provide a usable backup sight picture. The promise of a lower 1/3 co-witness with my iron sights was especially appealing.
The mount arrived in typical Trijicon packaging, clean and professional. The black anodized finish looked incredibly durable, and the quick-release lever felt solid and well-machined. It had a reassuring weight that spoke to the quality of the materials.
I considered other mounts like the Scalarworks LEAP/04 and the American Defense AD-RMR, but the Trijicon mount’s reputation for ruggedness and the established reliability of their quick-release mechanisms ultimately won me over. I was also drawn to the simple, clean aesthetics of the Trijicon mount.
Initially, I was excited about the potential for a consistent zero and a clear field of view. I was also cautiously optimistic about the quick-release mechanism, hoping it would live up to the hype. My initial excitement was mixed with the usual apprehension about whether it would truly perform as advertised in real-world conditions.
Real-World Testing: Putting Trijicon RMR Quick Release 1/3 Co-Witness Mount Black 1.80″ to the Test
First Use Experience
I first tested the Trijicon RMR Quick Release 1/3 Co-Witness Mount Black 1.80″ at my local outdoor range, mounting it on my AR-15 pistol. I focused on rapid target acquisition drills and zeroing the RMR after each detachment and reattachment. It was a sunny day with a slight breeze, perfect for shooting.
The mount held zero surprisingly well after multiple detachments and reattachments. The lower 1/3 co-witness was perfect. It gave me a clear view through the RMR, with the iron sights sitting neatly in the lower portion of the optic window, ready for immediate use if needed. The quick-release lever was intuitive and easy to operate, even with gloves on.
No issues arose during the first range session. I was pleasantly surprised by how securely the mount locked onto the Picatinny rail. The RMR felt rock solid, and there was no noticeable wobble or movement.
Extended Use & Reliability
After several months of regular use, the Trijicon RMR Quick Release 1/3 Co-Witness Mount Black 1.80″ has held up remarkably well. I’ve used it in various conditions, including rain, mud, and dusty environments during several training sessions. The mount has consistently maintained its zero and quick-release function.
There are no visible signs of wear and tear, aside from a few minor scratches on the anodized finish. I attribute this to the mount’s robust construction and the high-quality 7075 Aluminum. Cleaning is simple; a quick wipe down with a cloth is all it takes.
Previously, I used a cheaper, fixed mount that constantly lost zero and was a pain to remove. The Trijicon mount drastically outperforms that previous experience, providing unparalleled reliability and ease of use. The consistent zero retention and quick detach feature have made a huge difference in my shooting experience.
