The MBUS (Magpul® Back-Up Sight) is a low-cost, color injection molded, folding backup sight, designed to work as a standalone iron sight or co-witnessing rear sight for improved target acquisition and consistent field performance in the event of a dead battery or cracked lens with your red dot or reflex sight. Impact-resistant polymer construction provides superior corrosion resistance and easily withstands years of use and abuse for improved reliability, while the spring-loaded design delivers rapid deployment in fast-action tactical scenarios. Better yet, the dual aperture MBUS Rear Sight is adjustable for windage and fits most 1913 Picatinny rail-equipped firearms.
