    The MBUS (Magpul Back-Up Sight) is a low-cost, color injection molded, folding AR 15 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 AR15/M16 platform.

    Made in U.S.A.

    Features

    • Impact resistant polymer construction provides light weight and resists operational abuse
    • Spring-loaded flip up sight easily activated from either side or by pressing the top
    • Detent and spring pressure keeps sight erect but allows for unobstructed folding under impact, etc.

    • Protective wings shield the dual, same plane flip apertures

    • Detent knob easily and positively adjusts windage
