First Thoughts on the GEISSELE SPR PRN MRO 1/3 CO-WIT DDC
The GEISSELE SPR PRN MRO 1/3 CO-WIT DDC – that’s a mouthful, but it represents a serious piece of kit for those serious about their optics mounting solutions. Geissele Automatics is known for its unwavering commitment to quality and precision, and this mount seems to be no exception. It promises a rock-solid platform for the Trijicon MRO, placing it at a lower 1/3 co-witness height, and finished in their signature Desert Dirt Color (DDC).
I’d been searching for a lower 1/3 co-witness mount for my MRO on my go-to AR-15 build. I wanted something bombproof that wouldn’t shift zero under hard use. I was torn between this Geissele mount, a Scalarworks LEAP mount, and a Midwest Industries QD mount. Ultimately, the Geissele’s reputation for ruggedness and the appealing DDC finish swayed me.
Out of the box, the GEISSELE SPR PRN MRO 1/3 CO-WIT DDC exudes quality. The DDC anodizing is flawless, and the machining is incredibly precise. It feels substantial, instilling confidence that it can withstand serious abuse. My first impression was excitement; this mount looked like exactly what I needed.
Real-World Testing: Putting GEISSELE SPR PRN MRO 1/3 CO-WIT DDC to the Test
First Use Experience
My first opportunity to truly test the GEISSELE SPR PRN MRO 1/3 CO-WIT DDC was at a two-day carbine course at a local range. The course involved a lot of movement, transitions, and rapid target acquisition. The mount held the MRO securely throughout, with no loosening or shift in zero.
The weather was typical for early summer: hot and dusty. The DDC finish proved surprisingly resistant to scratches and held up well to the grit and grime. The lower 1/3 co-witness was perfect, allowing for comfortable use of the MRO while still providing access to my iron sights if needed. There was no need to adjust to the mount; it felt intuitive from the start.
Extended Use & Reliability
After several months of regular range trips and one particularly brutal hunting trip in the mountains, the GEISSELE SPR PRN MRO 1/3 CO-WIT DDC has proven to be incredibly reliable. There are no signs of wear and tear beyond some minor cosmetic blemishes. I clean my rifles regularly, and the mount is easy to wipe down and keep free of debris.
Comparing it to my previous experience with a cheaper, no-name mount, the difference is night and day. That old mount would constantly loosen, and I had to retighten it regularly. The Geissele mount, in contrast, remains rock solid and inspires confidence. It definitely outperforms my expectations.
