OVERVIEW
The MBUS (Magpul® Back-Up Sight) is a low-cost, color injection molded, folding back-up sight. The dual aperture MBUS Rear Sight is adjustable for windage and fits most 1913 Picatinny rail equipped weapons, but is specifically tailored to the AR15 / M16 platform.

- Protective wings shield the dual, same plane flip apertures
- Sight can still be folded with either large or small aperture in position
- Detent knob easily and positively adjusts windage
- Polymer construction provides light weight and resists operational abuse
