Magpul MBUS Gen 2 Rear Sight: Reliable Back-Up Optics
The MBUS (Magpul Back-Up Sight) represents a straightforward approach to defensive rifle sighting: a durable, affordable folding rear sight that works when you need it.

- Spring-loaded flip-up mechanism easily activated from either side or via top release button
- Windage adjustment via detent knob for precise zero
- Protective wings shield the apertures from damage
- Folds flat when not in use, even with either aperture selected
- Color injection-molded construction for durability and corrosion resistance
- Made in the USA
Technical Specifications
The sight is specifically tailored for AR-15 and M16 platforms and fits standard 1913 Picatinny rails. Adjustment rates are:
- 0.7 MOA per click with a 14.5" sight radius
- 0.5 MOA per click with a 20" sight radius
Important Mounting Notes
The MBUS rear sight cannot be mounted to railed gas blocks due to heat concerns. It is compatible with standard receiver-mounted Picatinny rails. The front MBUS must be mounted to a railed fore-end on the same plane as the receiver rail and is not compatible with MOE Hand Guards.
A proven choice for shooters who value simplicity and reliability.
