The MBUS 3 incorporates the best features, strengths, and value of our 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 .44” when folded and 1.15” at its widest point. Constructed of our impact-resistant polymer, it’s lightweight and extremely durable and its aesthetics and features are derived from the MBUS Pro line. With the same spring-loaded technology as its predecessor, it can be deployed with an ambidextrous push-button. It sits at standard AR-height when deployed and includes a rapid-select rear aperture system for changing conditions.
