The Magpul MBUS Pro LR flip-up rear sight for AR-15 platforms combines proven MBUS Pro ergonomics with elevation adjustment capability to extend your aiming range. If you're running a dedicated optic but want a reliable backup sight, or you're setting up an iron-sight-only AR carbine, the Pro LR bridges the gap between close-quarters speed and distance precision. The all-steel construction delivers durability that outlasts plastic, and the tool-free adjustments mean you dial in your zero without fumbling for hex keys or screwdrivers.
What sets the Pro LR apart is the elevation adjustment wheel—a feature that lets you dial for targets at variable distances without switching sights or accepting fixed-distance compromises. Deploy the sight and it sits at standard AR sight height; stow it and the positive detents keep it low enough that it won't snag in your pack or catch on gear. This flip-up design works on any Picatinny rail and resists corrosion, which matters if your rifle sees field use, hunting conditions, or regular shooting in less-than-ideal weather.
Magpul built the Pro LR in the USA, and the steel construction combined with no-tool adjustments and a compact profile makes it a smart choice whether you're running it as a primary sight system or backing up a primary optic on a carbine, service rifle, or hunting platform.

Frequently Asked Questions
Will the MBUS Pro LR fit my AR-15?
Yes, it mounts on any MIL-STD-1913 Picatinny rail system, which is the standard rear rail on modern AR-15 receivers and uppers.
What's the difference between the MBUS Pro LR and other flip-up rear sights?
The Pro LR includes an elevation adjustment wheel, allowing you to dial for different target distances without switching sights or settling for a fixed-range compromise. The all-steel construction also provides greater durability and corrosion resistance than polymer alternatives.
Can I use this sight with an optic mounted on my rifle?
Yes. The MBUS Pro LR works as a backup iron sight behind a primary optic, or as a standalone rear sight system. When stowed, its low profile won't interfere with optic mounting or sight picture.
Do I need special tools to adjust elevation?
No. The elevation adjustment wheel requires no tools—you can dial in adjustments by hand in the field or at the range.
