Magpul MBUS 3 Front Folding Back Up Sight OD Green

The MBUS 3 represents the next generation in Magpul’s MBUS (Magpul Back-Up Sight) line, combining the best features and value from the original MBUS and MBUS Pro Sights into a comprehensive back-up sight system. The design is significantly more compact than the standard MBUS, measuring just 0.44″ high when folded and 1.15″ at its widest point. Drawing its aesthetic from the MBUS Pro, the MBUS 3 Front Sight is built from impact-resistant polymer that keeps weight down while delivering exceptional durability. An ambidextrous push-button activates the same spring-loaded deployment mechanism found on previous generations. When deployed, the MBUS 3 sits at standard AR-height. The front sight includes tool-less elevation adjustments and a dual width enhanced front sight matching the MBUS Pro design.
