    Product Description

    The Magpul 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 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.
    • Clamps to MIL-STD-1913 Picatinny/STANAG 4694 receiver rail and provides the same height-over-bore as standard A2 irons
    • Protective wings shield the dual, same plane flip apertures
    • Sight can still be folded with either large or small aperture in position
    • Detent knob easily and positively adjusts windage

    Specifications:

    • Weight, w/ hardware: 1.3 oz.
    • Height above rail, stowed: ~0.51 in.
    • Center of aperture to top of rail: 1.42 in.
    • Length, stowed: 2.6 in.
    • Length, deployed: 1.5 in.

      Great Rear Sight

      Posted by Raphael on 3rd Jul 2018

      At first I was a little skeptic about polymer sights since I have a pair of Troy sights on my AR, but these held up really great. I have them on my KSG and was a little worried about the kick throwing them off. Stayed in place perfectly. Would definitely recommend.

      Pretty standard rear sight, light weight due to the polymer construction. Fast shipping.

      Magpul MBUS Rear Sight

      Posted by Michael in Tulsa on 4th May 2018

      I already have one of these on my 5.56 upper, bought a .300 Blackout upper and needed a rear sight for it. I like having the iron sights along with any scope I might use. Price was excellent, best I could find via the internet. Shipping was fast! Will look at Arms Unlimited next time I want to purchase firearm accessories.
