Magpul MBUS3 Flip-up Sights

Combination of the MBUS Pro & MBUS


The Magpul MBUS (Magpul Back Up Sights) has been an industry standard when it comes to flip up iron sights. Magpul created the MBUS 3 as essentially a combination of all the best features of the MBUS and MBUS Pro. The MBUS 3 features a spring loaded flip up design, tool-less adjustments, streamlined profile, multiple aperture options and a lightweight polymer construction. 

The MBUS 3 work great as back up sights but can also work as a primary sighting system.
