The Magpul MBUS 3 Front Sight (MAG1166-FDE) is a compact, rugged, and lightweight backup sight designed for AR-platform rifles and carbines. Finished in Flat Dark Earth for enhanced camouflage and aesthetic appeal, this sight is built from impact-resistant polymer, offering exceptional durability without adding unnecessary weight. It features a low-profile design that sits closer to the rail when folded, making it ideal for use alongside optics. The spring-loaded mechanism allows for fast, ambidextrous deployment at the push of a button, while the tool-less elevation adjustment and dual-width front sight post provide precise aiming control. Compatible with all MIL-STD-1913 Picatinny rails, the MBUS 3 Front Sight is a reliable and modern solution for shooters who demand performance and versatility in any environment.
