    Product Description

    The MBUS (Magpul Back-Up Sight) is a low-cost, color injection molded, folding back-up sight. The MBUS Front Sight is adjustable for elevation and fits most 1913 Picatinny-railed hand guards, 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 most any MIL-STD-1913 Picatinny/STANAG 4694 railed hand guard* and provides the same height-over-bore as standard A2 irons
    • Protective wings shield the spring-locking A2 front sight post
    • Elevation adjustment tool included, but most aftermarket A2 front sight adjustment tools may be used as well

    Specifications:

    • Weight, w/ hardware: 1.2 oz.
    • Height above rail, stowed: ~0.51 in.
    • Length, stowed: 2.6 in.
    • Length, deployed: 1.5 in.
     
    ELEVATION ADJUSTMENT
    ~1.6 MOA (1.886"/100m) per click with a 14.5" sight radius
    ~1.2 MOA (1.367"/100m) per click with a 20" sight radius
     
    *NOTE: Cannot be mounted to a railed gas block due to excess heat issues. Front MBUS must be mounted to a railed fore end on the same plane as the receiver rail. Because of this the sight is also not compatible with MOE Hand Guards.

      Nothing But Good Things to Say

      Posted by Pete Sake on 18th Aug 2020

      Prices are good, shipping is fair and inventory seems to be better than other sites I’ve used in terms of having the items actually in stock.

      Slow shipping

      Posted by Unknown on 2nd Aug 2020

      Product itself is as expected and functions perfectly, the reason for the 3 stars is due to the extremely slow shipping process. My order took two weeks to be received from the order date

      Strong reliable sights

      Posted by Joseph Maddux on 23rd Jun 2020

      these are great sights, especially given that they are polymer. I recommend Magpul sights always as a strong base set of sights.

      Cheaper alternative

      Posted by Antonio D. on 21st Aug 2019

      I now have both the pros and polymer. Very nice fit and finish. The spring assist is quite nice. No issues thus far.
