The MAGPUL Gen3 MBUS Front Back-Up AR15 Sight in Olive Drab Green (MAG1166-ODG) incorporates the best features, strengths, and value of their original MBUS and MBUS Pro Sights in a feature-packed back-up sight system.
Significantly reduced in size from the MBUS, it sits at just 0.44” high when folded and 1.15” at its widest point. Its aesthetics are derived from the MBUS Pro, but the MBUS 3 Front Sight is constructed of an impact-resistant polymer, making it lightweight and highly durable. Featuring the same spring-loaded technology as its predecessor, they can be deployed with an ambidextrous push-button. The MBUS 3 sits at standard AR height when deployed.
The MBUS 3 Front Sight includes toolless elevation adjustments and a dual-width enhanced front sight similar to the MBUS Pro.
