The Magpul MBUS 3 Front Sight delivers enhanced target acquisition and improved sight picture over standard polymer backup sights. This third-generation design incorporates user feedback and engineering refinements to create a more robust and precise aiming solution for AR-15 and M4 platforms.
What Makes This Different
The MBUS 3 features a redesigned sight post geometry that provides a cleaner sight picture and faster target alignment compared to previous generations. The enhanced spring-loaded detent system ensures positive lockup in both deployed and folded positions, while the streamlined profile reduces snag hazards during weapon manipulation. Constructed from impact-resistant polymer, this sight maintains zero retention through repeated deployments and environmental exposure.Key Features
