Magpul MBUS Pro Sight Rear Black

The Magpul MBUS Pro Sight Rear in Black is a professional-grade backup iron sight designed for modern tactical rifles and carbines. Engineered for law enforcement, military, and civilian operators who demand reliability when primary optics fail, this rear sight bridges the gap between affordability and durability. The MBUS Pro platform has proven itself across thousands of deployments, earning trust among users who understand that backup sights aren't optional—they're essential redundancy.

Built from reinforced polymer with a steel witness line and fully spring-loaded design, the Magpul MBUS Pro Sight Rear delivers rapid target acquisition without the weight penalty of all-steel alternatives. The sight features a precise aperture mechanism with audible and tactile feedback, allowing consistent zero maintenance and confident adjustments under stress. Its low-profile footprint—measuring just 3.25 inches in length and weighing only 0.16 pounds—ensures minimal interference with co-witness or absolute co-witness setups while maintaining exceptional durability in high-round-count environments.

This rear sight pairs seamlessly with the Magpul MBUS Pro Front Sight to form a complete backup system, offering true 1913 Picatinny rail compatibility across AR-platform rifles, carbines, and other MIL-STD equipped firearms. Whether mounted on mid-length, carbine, or rifle-length uppers, the MBUS Pro Sight Rear performs identically in field conditions. Operators favoring primary red dot or LPVO optics will appreciate the versatility—flip the sight up only when needed, or maintain it in permanent co-witness position for immediate iron sight capability without optic dependency.
