The Trijicon RMR Quick Release 1/3 Co-Witness Mount Black 1.80″ Made a Bold First Impression
The Trijicon RMR Quick Release 1/3 Co-Witness Mount Black 1.80″ promised to be the solution I needed for effectively mounting my Trijicon RMR to my AR-15. I had been running an older, fixed-height mount that offered no co-witness with my iron sights, making for a cluttered sight picture and a reliance solely on the optic. I was excited to try this quick-release mount for its potential to quickly remove the RMR if needed and its lower 1/3 co-witness capability.
I had been searching for a reliable quick-release mount that wouldn’t break the bank. I had considered Scalarworks and American Defense Manufacturing (ADM) mounts, but the Trijicon offering seemed to strike a good balance between quality and price. I was particularly drawn to the Trijicon name and reputation for ruggedness and durability.
Upon unboxing, the mount felt solid and well-constructed. The black anodized finish was clean and even, and the quick-release lever felt robust. It had a satisfying click when locking into place. The weight felt appropriate, not too heavy to add unnecessary bulk to the rifle, but substantial enough to inspire confidence.
Compared to my previous fixed mount, the Trijicon mount appeared far more refined. Its quick-release mechanism felt far more secure than some of the cheaper options I’d seen online. My initial impression was excitement and a sense of relief that I had potentially found the perfect solution.
Real-World Testing: Putting Trijicon RMR Quick Release 1/3 Co-Witness Mount Black 1.80″ to the Test
First Use Experience
My first test of the Trijicon RMR Quick Release 1/3 Co-Witness Mount Black 1.80″ was at an outdoor shooting range. The mount was installed on my AR-15 flat top receiver, and I ran several drills to assess its zero retention and ease of use. I specifically focused on the quick-release feature.
The weather was sunny and dry, providing ideal shooting conditions. The mount held zero perfectly throughout my initial testing. The quick-release lever was easy to operate, even with gloves on, and the RMR could be removed and reattached within seconds.
I did notice that the lever required a bit of force to fully lock into place. However, this reassured me that it wouldn’t accidentally disengage during use. The lower 1/3 co-witness was exactly as advertised, providing a clear sight picture with the iron sights visible in the lower portion of the RMR window.
Extended Use & Reliability
After several months of regular use, the Trijicon RMR Quick Release 1/3 Co-Witness Mount Black 1.80″ has proven to be incredibly reliable. I’ve used it during multiple range trips, in varying weather conditions (including light rain and dusty environments), and it has consistently performed without issue. There is no discernible play or wobble after repeated removal and reattachment.
The finish has held up well, with only minor signs of wear around the quick-release lever. The mount is easy to clean with a simple wipe down using a damp cloth and gun solvent. Compared to my previous mount, this Trijicon model offers far greater versatility and peace of mind.
The quick-release mechanism continues to function flawlessly. It provides confidence that the RMR can be removed quickly if the optic fails or if I need to switch to iron sights. The mount has exceeded my expectations in terms of durability and performance.
