Trijicon MRO Adapter 1.663″ Black Review

First Thoughts on the Trijicon MRO Adapter 1.663″ Black

The Trijicon MRO Adapter 1.663″ Black is a seemingly simple piece of kit, but it plays a crucial role in optimizing the performance and usability of the Trijicon Miniature Rifle Optic (MRO). This adapter elevates the MRO to a lower 1/3 co-witness height, providing a more natural and comfortable sight picture for many shooters. This ensures a seamless transition between the optic and iron sights.

I’ve always been a proponent of co-witnessing optics with iron sights, but achieving the right height can be a frustrating endeavor. Standard mounts often leave the optic too low or too high, compromising both speed and accuracy. Finding an adapter that provided the correct height without sacrificing durability and stability was paramount.

Upon receiving the Trijicon MRO Adapter 1.663″ Black, I was immediately impressed by its solid construction and clean finish. The black anodized aluminum exudes quality, promising resistance to the elements and demanding field conditions. Its lightweight design was also a welcome surprise.

Compared to some other MRO mounts I’ve used, this adapter seemed less bulky and more streamlined. Many aftermarket mounts either compromise on aesthetics or durability. I chose the Trijicon adapter because I trust their reputation for building robust and reliable products.

My initial impression was one of cautious optimism. While the adapter appeared well-made, the true test would be how it performed in real-world scenarios. I was eager to mount it on my rifle and see if it truly delivered on its promise of a perfect lower 1/3 co-witness.

Real-World Testing: Putting Trijicon MRO Adapter 1.663″ Black to the Test

First Use Experience

I tested the Trijicon MRO Adapter 1.663″ Black at my local outdoor shooting range. The weather conditions were sunny and dry, providing ideal visibility for zeroing the optic. I used my AR-15 platform rifle chambered in 5.56 NATO.

The adapter was extremely easy to install, requiring only a few minutes to mount both the adapter to the rail and the MRO to the adapter. The lower 1/3 co-witness was immediately apparent, providing a clear sight picture without obstructing my view when using the iron sights. The raised optic improved my head position, and reduced strain during rapid target acquisition.

There were no immediate issues after the first-time use. The adapter felt rock solid, and maintained zero throughout the initial testing session. The height was perfect for my cheek weld, and allowed for quick and accurate shots.

Extended Use & Reliability

After several weeks of regular range sessions and a couple of weekend training courses, the Trijicon MRO Adapter 1.663″ Black has proven to be incredibly durable and reliable. There are no visible signs of wear and tear. The finish still looks pristine.

The adapter remains securely mounted to my rifle’s rail and shows no signs of loosening or shifting. I have cleaned the rifle and adapter several times, and the adapter is easy to wipe down and maintain. The black anodized finish resists scratches and corrosion.

Compared to other lower quality optic mounts, this adapter has far exceeded my expectations. It maintains zero consistently, and provides a stable platform for the MRO optic. This gives me confidence in its performance under any conditions.
