Magpul MBUS Pro Rear Sight – Folding Iron Sight

The Magpul MBUS Pro Rear Sight gives AR platform shooters a dependable back-up sighting option when a primary optic goes down or when a compact folding iron sight is needed for close to mid-range work. It's built for duty use, competition, and range rifles alike, offering a low-bulk profile that stays out of the way until you need it.

This rear sight is machined from case-hardened steel and finished with a Melonite QPQ coating for serious resistance to wear and corrosion. Windage is adjustable via a low-profile knob with no tools required, and positive detents lock the sight at standard AR sight height when deployed or fold it flush when stowed so it never snags.
