    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.

      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.

      Ordered front sight for my AR15 and am delighted with my purchase. Would definitely recommend Arms Unlimited to anyone wanting to buy guns, parts, or accessories.
