Magpul MBUS 3 Front Sight – Flat Dark Earth


The Magpul MBUS 3 front sight combines the best of both worlds from Magpul’s line of back up sights. The low profile and minimalist design from the MBUS Pro combined with the lightweight impact resistant polymer of the original MBUS sights give you a cost effective and feature packed solution for mounting flip up sights on your rifle. When folded, the MBUS 3 sight is only .44” high and only 1.15” wide, so it sits on slimmer rails without overhanging. Additionally, the Magpul MBUS 3 front sight features the same spring-loaded technology that can be deployed by the press of an ambidextrous button.

    First set of mbus3 backup sights and so far it’s a huge improvement over the 2nd gen. Very slim design and the tool free adjustment was a perfect addition.
