Magpul MBUS Rear Folding Sight Black for AR-15/M16

The Magpul MBUS Rear is a folding back-up sight designed for AR-15/M16 platforms and most weapons equipped with a 1913 Picatinny rail. Its dual apertures, polymer construction, and windage adjustment provide a practical sighting option for compatible setups.

The spring-loaded sight can be activated from either side or by pressing the top release. Protective wings shield the dual, same-plane flip apertures, and the sight can be folded with either aperture selected. It is not suitable for mounting to a railed gas block because of excess heat concerns, and it is not compatible with MOE Hand Guards. Made in the USA.
