Let’s Talk About Magpul MBUS Rear Flip-Up Back Up Sight Gen 2, – 1 out of 9 models
The Magpul MBUS Rear Flip-Up Back Up Sight Gen 2 is a ubiquitous piece of kit in the AR-15 world, and for good reason. It’s a low-cost, durable, and reliable back-up sight that offers a practical solution for those running optics or anticipating optic failures. These sights provide a quick and easy transition to iron sights, ensuring you stay in the fight when your primary optic goes down.
I decided to give the Magpul MBUS Rear Flip-Up Back Up Sight Gen 2 a try because I was looking for a lightweight and reliable back-up sighting system for my AR-15. I wanted something that wouldn’t break the bank but would still offer decent performance in a pinch. My primary optic is great, but Murphy’s Law exists, and having a dependable back-up is crucial.
My first impression upon unboxing was that the MBUS sight felt surprisingly solid for being made of polymer. The construction seemed robust, and the flip-up mechanism felt positive and secure. It’s lightweight, which is a huge plus since I’m trying to keep my rifle as maneuverable as possible.
Compared to similar polymer sights from other manufacturers, like some offerings from UTG or ProMag, the Magpul MBUS sights seemed to have a higher level of fit and finish. I considered Troy Industries’ metal flip-up sights for their bomb-proof reputation, but the price difference was significant, and for a back-up, I felt the MBUS offered the best balance of cost and functionality. I was definitely excited to try it out at the range.

First Use Experience
I first tested the Magpul MBUS Rear Flip-Up Back Up Sight Gen 2 at my local outdoor shooting range on a bright, sunny day. The rifle was zeroed at 50 yards, and I wanted to confirm the MBUS sight’s zero and usability. Initial adjustments were straightforward using a small flathead screwdriver.
The sight performed admirably even after leaving the rifle in direct sunlight. Acquiring the target was quick and intuitive, and the windage adjustments felt positive with audible clicks. I did encounter a slight issue in that the detent knob was a little stiff at first, requiring a bit more force to turn than expected, but it loosened up with a few adjustments.
Extended Use & Reliability
After several months of regular use, the MBUS sight continues to hold up well. There are no noticeable signs of wear and tear, despite being exposed to varying weather conditions. I have used it in temperatures ranging from 30°F to 95°F.
