Magpul MBUS Rear Flip-Up Back Up Sight Gen 2, – 1 out of 10 models Review

Let’s Talk About Magpul MBUS Rear Flip-Up Back Up Sight Gen 2, – 1 out of 10 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. Magpul has a reputation for durable, functional, and affordable accessories, and the MBUS Gen 2 rear sight generally lives up to that reputation. Its simple design, polymer construction, and spring-loaded flip-up mechanism make it a popular choice as a secondary sighting system.

I was looking for a reliable, low-profile rear sight to complement a red dot optic on my patrol rifle. If the optic failed, I needed something I could quickly deploy and trust. I wanted something lightweight and durable, without breaking the bank.

My initial thought was, “This is surprisingly light.” The polymer feels robust, but the overall weight is minimal, which is important when you’re already carrying a heavy load. The flip-up mechanism felt positive and quick, snapping into place with a satisfying click.

I considered the Troy Industries folding rear sight and the Midwest Industries Combat Rifle Sight. Ultimately, I chose the Magpul MBUS Rear Flip-Up Back Up Sight Gen 2 because of its reputation for reliability and its significantly lower price point. I wanted functionality and dependability, not necessarily high-end features.

I was cautiously optimistic. I’d heard good things about the Magpul MBUS Rear Flip-Up Back Up Sight Gen 2, but I’ve also learned over the years that not everything lives up to the hype. I was hoping for a simple, reliable back-up sight, and so far, my first impression hinted that it could perform as intended.
