The Magpul MBUS 3 Front Sight combines the proven durability and reliability of the MBUS line with a more compact, streamlined profile. Made from impact-resistant polymer with corrosion-resistant hardware, it’s built to withstand harsh conditions while remaining lightweight and low-profile when folded.
This front sight features a spring-loaded ambidextrous release for quick deployment and can be activated from either side. The elevation adjustment is completely tool-free, allowing easy zeroing in the field without specialized gear.
Optimized for Picatinny rail mounting, the MBUS 3 Front Sight is compatible with most AR-15/M4/M16 platforms and co-witnesses with most red dot optics. It sits low when folded to reduce snagging and interference, and the protective wings shield the sight post from impact.
