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.

    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.

    Great front 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.
