The Magpul MBUS Gen 3 Front AR-15 Back-Up Sight is a lightweight and low-profile backup sighting solution designed for the AR-15/M4 platform. Crafted from impact-resistant polymer, this front sight combines the sleek profile and tool-free design of the MBUS Pro with the affordability and spring-loaded flip-up mechanism of the original MBUS series.

Optimized for free-floated handguards, the MBUS Gen 3 Front Sight features a slim design that folds down to just 0.44 inches above the rail, occupying minimal rail space when stowed. The elevation adjustment drum allows for easy, tool-free adjustments, eliminating the need for specialized tools.
