The original Magpul Back Up Sights (MBUS) were well loved for their combination of functionality and affordability. Now Magpul has released the second generation of the MBUS. Like the originals, the Gen 2 MBUS front and rear sights will be very reasonably priced and be molded in variety of the typical Magpul colors.
The Gen 2 MBUS improves on the original by adding a detent to the front sight so that the front sight post is locked in place. Both the front and rear have been made lower in profile so that they work with a wider variety of optics.
Both the front and rear MBUS can be found on Magpul’s website and should be on dealer shelves shortly.
