It’s the Magpul Back-Up Sight (MBUS) – an economical injection-molded polymer folding sight that’s certain to become your best friend whether you make it your primary or secondary aiming mechanism!
This windage-adjustable rear sight fits most 1913 Picatinny rail-equipped firearms (although it is specifically designed for the AR-15/M16 platform). Press the top of the spring-loaded sight to watch it pop into action. Count on its protective wings to shield its dual same-plane flip apertures. Easily adjust for windage thanks to the MBUS’s intuitive detent knob!
Don’t worry about damaging Magpul’s proven impact-resistant polymer construction. And thanks to its inherent detent and spring pressure, the sight reliably remains erect *but also* folds under the force of impact. In other words, you don’t have to be very careful with the MBUS. It takes a licking and keeps on ticking! If the PMAG has already won your respect, then the MBUS is a natural addition to your rifle.
