Let’s Talk About Magpul Industries MBUS Pro LR Top Mounted
The Magpul Industries MBUS Pro LR Top Mounted sight is a robust, all-steel back-up sighting solution designed for the modern sporting rifle. Magpul is a trusted name, and this offering promised enhanced accuracy and durability over standard polymer back-up sights. I was looking for a low-profile, reliable back-up sight that wouldn’t break the bank, but still offered long-range adjustability.
Years of relying on standard A2 front sights and detachable carry handles left me wanting a more streamlined sighting system. I needed something that wouldn’t interfere with my primary optic but was instantly available if the need arose. The MBUS Pro LR seemed to hit that sweet spot.
Unboxing the MBUS Pro LR, the first thing that struck me was its solid, weighty feel. The all-steel construction is immediately apparent, inspiring confidence in its ability to withstand abuse. The Melonite finish gives it a sleek, matte black appearance that blends seamlessly with the rifle.
I considered other options like the Troy Industries folding battle sights and the Knights Armament Micro BUIS. Ultimately, the Magpul offered a better value proposition with its combination of steel construction, low profile, and long-range adjustability, all at a more accessible price point. The Troy sights, while excellent, were significantly more expensive.
My initial impression was overwhelmingly positive. The sight exudes quality and feels like a significant upgrade over polymer alternatives. I was excited to get it mounted and zeroed.
Real-World Testing: Putting Magpul Industries MBUS Pro LR Top Mounted to the Test
First Use Experience
I first tested the Magpul Industries MBUS Pro LR Top Mounted at my local range during a qualification session. Conditions were relatively mild, with clear skies and a slight breeze. I mounted the sight on the Picatinny rail of my AR-15’s upper receiver, behind my primary red dot optic.
The MBUS Pro LR proved intuitive to use. Deploying the sight is quick and positive, snapping into place with a satisfying click. Adjusting the windage and elevation was also straightforward, with clearly marked graduations.
The only initial hiccup was getting used to the smaller aperture compared to my usual sights. However, after a few practice shots, I quickly adapted. The elevation adjustment wheel for 200-600 meter distances worked perfectly, allowing for easy zeroing.
Extended Use & Reliability
After several months of regular use, the Magpul Industries MBUS Pro LR Top Mounted continues to perform flawlessly. There are no signs of loosening or play. The Melonite finish has proven remarkably resistant to scratches and wear, even after numerous trips to the range.
Cleaning is simple: a quick wipe down with a lightly oiled cloth is all it takes to keep the sight in top condition. I haven’t experienced any issues with corrosion or rust, despite occasionally exposing it to damp conditions.
Compared to the plastic back-up sights I’ve used in the past, the MBUS Pro LR is a clear winner. It offers superior durability, more precise adjustments, and a far more confident shooting experience. The peace of mind knowing I have a dependable back-up sighting solution is invaluable.
