Magpul MBUS Flip-Up Backup Sights - MPIMAG247OD

The Magpul MBUS Flip-Up Backup Sights (MPIMAG247OD) are spring-loaded auxiliary aiming systems designed for AR-15 and M16 platform rifles equipped with Picatinny rail handguards. These backup sights provide a reliable secondary sighting option when primary optics are compromised or unavailable, making them essential for both professional operators and trained shooters who require fast target acquisition.

Constructed from color-injected polymer, the MBUS delivers minimal weight at 0.13 lbs while maintaining durability in field conditions. The flip-up design allows for quick deployment, and the dual aperture sight provides versatility in target acquisition without requiring batteries or electronics.

This sight configuration is ideal for operators using modern optic setups—such as red dots, LPVOs, or magnified scopes—who need a mechanically-indexed backup solution. Common deployment scenarios include duty rifles, patrol carbines, competition platforms, and training systems where backup iron sights are crucial for mission success.
