What Makes Trijicon RMR/SRO Full Co-Witness Mount w/ Trijicon Stand Out?
The Trijicon RMR/SRO Full Co-Witness Mount w/ Trijicon is a purpose-built solution for shooters seeking a seamless integration of their red dot optic with their iron sights. Trijicon is renowned for its rugged and reliable optics, and this mount aims to extend that reputation to the mounting system itself. What immediately caught my eye was the promise of a full co-witness, allowing for instant transition between optics and iron sights in critical situations.
I was looking for a way to modernize my AR-15 without sacrificing the redundancy of iron sights. I wanted a rock-solid mounting solution that wouldn’t break the bank, but still offered the Trijicon level of quality I’ve come to expect.
Upon unboxing, the mount felt substantial, a testament to the 7075-T6 aluminum construction. The matte black anodized finish looked clean and professional. The quick-release mechanism appeared robust and easy to manipulate, promising tool-less installation and removal.
I considered other mounts from companies like Scalarworks and Midwest Industries. However, the Trijicon mount offered a more streamlined design and a slightly lower price point, while still delivering the full co-witness feature I desired. It felt like the optimal balance of cost, features, and brand reputation.
My first impression was overwhelmingly positive. The mount felt well-made and thoughtfully designed, sparking excitement for the prospect of a truly integrated sighting system. It seemed like a significant upgrade from my previous, less refined mounting solution.
Real-World Testing: Putting Trijicon RMR/SRO Full Co-Witness Mount w/ Trijicon to the Test
First Use Experience
I first tested the Trijicon RMR/SRO Full Co-Witness Mount at my local outdoor shooting range. The weather was slightly overcast, but dry, providing decent visibility for dialing in the optic. I mounted the mount on my AR-15 flat top receiver with a Trijicon RMR optic and Magpul MBUS Pro flip-up sights.
The mount performed flawlessly under controlled conditions. The full co-witness was immediately apparent, with the RMR dot sitting perfectly atop the front sight post when the iron sights were deployed. This allowed for rapid target acquisition and confident transitions between sighting systems.
Installation was incredibly easy, thanks to the tool-less quick-release mechanism. However, I did need to apply a fair amount of force to ensure the mount was securely clamped to the Picatinny rail. Initially, I was concerned about the height over bore, but after a few shots, it felt intuitive, particularly when moving between targets at varying distances.
Extended Use & Reliability
After several range trips and one carbine course, the Trijicon mount continues to perform admirably. There are no signs of loosening or shifting, even after hundreds of rounds fired. The mount has maintained its zero consistently, proving its reliability under recoil.
The matte black anodized finish shows minimal signs of wear, even after being exposed to typical range debris and handling. Cleaning is straightforward, requiring only a quick wipe down with a lightly oiled cloth. Overall, it has exceeded my expectations in terms of durability and ease of maintenance.
Compared to my previous mount, a generic riser block, the Trijicon RMR/SRO Full Co-Witness Mount offers a vastly superior experience. The full co-witness is a game-changer for quick transitions. The Trijicon mount is noticeably more stable and reliable.
