Magpul MBUS Gen 2 FDE Picatinny Rear Sight

The Magpul MBUS Gen 2 Rear Sight in Flat Dark Earth is the Gen 2 rear backup sight in color-molded tan polymer. It pairs with an FDE MBUS front or works behind a fixed front sight base. It flips up from either side or by pressing the top.

A spring and detent hold it upright but let it fold under impact, which protects the sight if the rifle is dropped. The dual apertures give a large opening for close work and a smaller one for precise shots. Windage is set with a detent knob.

Folded, it is 2.6 inches long and sits low enough to stay under most optics. For a lower folded profile, the MBUS 3 rear is the newer option. The FDE color matches tan Magpul furniture. Find tan MBUS front sights in our optics and rangefinders.
