Let’s Dive into Magpul Industries MBUS Rear Flip-Up Back Up Sight Gen 2
The Magpul Industries MBUS Rear Flip-Up Back Up Sight Gen 2 is a ubiquitous sight in the AR-15 world for good reason. Magpul has built a reputation for reliable, affordable, and well-designed polymer products, and the MBUS Gen 2 rear sight is a prime example. Its low profile, spring-loaded deployment, and windage adjustability make it a strong contender for anyone needing a backup sighting system.
My journey to this sight began with a growing collection of AR-15s, all sporting various optics. I realized that a red dot or holographic sight is amazing, until the battery dies, or the optic takes a hit. I wanted a reliable, low-profile backup that wouldn’t break the bank.
Unboxing the MBUS Rear Sight Gen 2, I was immediately struck by its simple, clean design. The polymer felt robust, not cheap, and the spring-loaded mechanism snapped the sight into place with a satisfying click. It felt solid, despite its light weight.
Compared to metal back up sights, which I’ve used extensively from companies like Troy and Midwest Industries, the MBUS Gen 2 felt less bulky and more streamlined. Ultimately, I chose the Magpul sight for its value and reputation. The price point made it an easy decision, as I wanted to outfit multiple rifles.
My first impression was overwhelmingly positive. I was excited to see how it performed at the range. The promise of a reliable backup sight, without sacrificing weight or aesthetics, was a compelling one.
