The modern marksman may need a replacement to a rear sight assembly or simply just an aperture for reference on where to aim. Built for rugged outdoor use, your rear sight is used to help keep you aligned with a target.
About this Sight System: The MBUS (Magpul Back-Up Sight) is a low-cost, color injection molded, folding back-up sight. The dual aperture MBUS Rear Sight is adjustable for windage and fits most 1913 Picatinny rail-equipped weapons, but is specifically tailored to the AR-15/M16 platform. This rear sight is equipped to be spring-loaded and built with a polymer construction giving it great adaptability and resistance.
Rear Sight: The rear sight is winged/hooded to protect the rear aperture and adjustment dials from rough use and environmental conditions.
Flip-Up: Spring Loaded - The MBUS rear sight uses a spring-assisted deployment solution to properly engage and align the sights when needed for use.
Construction: Polymer - This sight system is constructed from a high-strength reinforced polymer blend improving impact resistance and reducing glare.
