My first impression of Meprolight MPO Pro-S Closed Emitter 3 MOA Red Dot
The world of red dot optics is saturated, but when Meprolight throws their hat in the ring, you pay attention. The Meprolight MPO Pro-S Closed Emitter 3 MOA Red Dot promises rugged reliability and versatility, traits that resonate deeply with my experience in the tactical and outdoor gear realm. I was eager to see if this optic could truly live up to the legendary durability associated with Meprolight’s earlier offerings while providing the advanced features demanded by modern shooters.
For years, I struggled with open emitter red dots, constantly battling rain, snow, and debris obscuring my sight picture. This led me to search for a closed emitter system that didn’t compromise on clarity or field of view, especially in adverse conditions. The Meprolight MPO Pro-S caught my eye because of its enclosed design, selectable reticle, and reputation for toughness, all at a price point that didn’t break the bank.
Unboxing the MPO Pro-S was immediately reassuring. The optic felt solid and well-built, a compact little brick of anodized aluminum; its weight of 1.4 ounces felt significant enough to inspire confidence but light enough to not unbalance a pistol slide. The finish was clean and even, and the included battery was a welcome touch. Compared to the Trijicon RMR and Holosun 507K, both of which I have extensive experience with, the MPO Pro-S seemed to prioritize ruggedness over sleekness, a trade-off I was willing to explore.
My first impression was one of cautious optimism, I was excited to see if the Meprolight MPO Pro-S Closed Emitter 3 MOA Red Dot could actually deliver on its promise of rugged reliability and versatility.
Real-World Testing: Putting Meprolight MPO Pro-S Closed Emitter 3 MOA Red Dot to the Test
First Use Experience
I mounted the Meprolight MPO Pro-S on my Glock 19, taking advantage of its RMSc footprint. My initial testing took place at my local outdoor range, under a variety of lighting conditions from bright sunlight to overcast skies. The optic performed flawlessly right out of the box. The dot was crisp and clear, and the automatic brightness adjustment worked surprisingly well, quickly adapting to changing light conditions.
During the first range session, a sudden downpour provided an unexpected test of the MPO Pro-S’s weather resistance. While other shooters scrambled for cover, I continued firing, and the optic remained unaffected. Water beaded off the lens, and the sight picture remained clear. There was a slight adjustment needed to familiarize myself with the reticle selection; I found that the 3 MOA dot was ideal for precise shots, while the 33 MOA ring proved useful for rapid target acquisition at close range.
Extended Use & Reliability
After several months of consistent use, the Meprolight MPO Pro-S has proven to be remarkably durable. I’ve subjected it to regular range sessions, carried it during several hunting trips in dense brush, and even accidentally dropped my pistol (holstered, thankfully) onto a gravel surface. Aside from a few minor scratches on the housing, the optic has shown no signs of wear or performance degradation. Cleaning has been simple; a quick wipe with a microfiber cloth keeps the lens clear of dust and debris.
Compared to other red dots I’ve used, the MPO Pro-S stands out for its consistent performance and robust build quality. It’s not the flashiest or most feature-packed optic on the market, but it’s a reliable workhorse that inspires confidence in any situation. The battery life has also been impressive; I’m still on the original CR1632 battery, and the dot remains bright and clear.
