Product Overview
The Magpul MBUS 3 Front Sight is a low-profile, spring-loaded flip-up sight for AR-15 platforms. Designed to be the most compact MBUS yet, it sits just 0.47 inches above the rail when folded and deploys to standard A2 front sight height.
Tool-free elevation adjustment. Push-button activation. Polymer construction with steel-reinforced hardware points for durability. Compatible with all MIL-STD-1913 Picatinny rail systems.
Works as a backup for optics or as a standalone iron sight. Fits setups requiring minimal rail space or clearance under magnifiers, lasers, or lights.
