The Meprolight MPO-DF 3.5 MOA Open Pistol Sight w/RMR Footprint Made a Bold First Impression
In the world of pistol optics, finding a balance between quality, durability, and affordability can feel like searching for a unicorn. Enter the Meprolight MPO-DF 3.5 MOA Open Pistol Sight w/RMR Footprint. This red dot sight from Meprolight promises to deliver performance and reliability without breaking the bank, and as a seasoned outdoor and tactical gear specialist, I was eager to put it to the test.
My aging eyes were struggling with iron sights on my Glock 19, particularly in low-light conditions. I needed a red dot that offered a clear and crisp aiming point, rugged construction, and wouldn’t require a second mortgage to acquire. The Meprolight MPO-DF seemed to check all the right boxes, with its RMR footprint, 3.5 MOA red dot, and automatic/manual brightness control.
Unboxing the MPO-DF revealed a compact and well-made optic. Its weight felt reassuringly solid without being overly bulky, and the finish appeared durable and resistant to scratches. The sight came neatly packaged, giving an immediate impression of quality.
Compared to other budget-friendly red dots like the Sig Sauer Romeo5 or the Holosun HS403B, the Meprolight stood out with its dual brightness control system. While those other optics are solid choices, I wanted the flexibility of both automatic and manual adjustment for different lighting scenarios. I chose the Meprolight due to the promise of a robust build quality from a reputable manufacturer, and I was hoping to discover a hidden gem in the budget-friendly optic market.
My initial impression was positive. The sight felt well-built, the dot was crisp and clear, and the controls were intuitive. This Meprolight MPO-DF 3.5 MOA Open Pistol Sight w/RMR Footprint seemed like a solid piece of kit.
Real-World Testing: Putting Meprolight MPO-DF 3.5 MOA Open Pistol Sight w/RMR Footprint to the Test
First Use Experience
I first tested the Meprolight MPO-DF at my local indoor shooting range. The environment allowed me to zero the optic precisely. The range offered varied lighting conditions to assess the effectiveness of both the automatic and manual brightness adjustments.
The Meprolight MPO-DF 3.5 MOA Open Pistol Sight w/RMR Footprint performed admirably. The 3.5 MOA dot was easy to acquire, even for my aging eyes, and the brightness adjusted quickly and effectively in response to changing light levels. The manual override was useful for dialing in the perfect brightness for specific targets and preferences.
No major issues arose during the initial range session. I was particularly impressed with how well the optic maintained zero after the first 100 rounds. The quick target acquisition with the Meprolight was an improvement over my iron sights, noticeably increasing my speed and accuracy.
Extended Use & Reliability
After several months of use, the Meprolight MPO-DF continues to hold its own. I’ve put roughly 1,000 rounds through my Glock 19 with the optic mounted, and it has consistently maintained zero. There are no signs of loosening or shifting.
I’ve subjected the sight to some moderate abuse, including carrying the pistol in a Kydex holster during outdoor training sessions. The Meprolight MPO-DF 3.5 MOA Open Pistol Sight w/RMR Footprint shows only minor cosmetic wear. The lens remains scratch-free. Cleaning the optic is straightforward. A simple wipe with a microfiber cloth is all that’s needed to remove fingerprints or debris.
Compared to a higher-end Trijicon RMR I’ve used on other pistols, the Meprolight doesn’t quite match the same level of refinement and durability. However, for the price, it far exceeds my expectations and delivers reliable performance. It is an extremely cost effective alternative!
