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.


An elevation adjustment tool is included, but most aftermarket A2 front sight adjustment tools may be used as well.


FEATURES

  • Spring-loaded flip up sight
  • Easily activated from either side or by pressing the top
  • Protective wings shield the spring-locking A2 front sight post
  • Impact resistant polymer construction provides light weight and resists operational abuse
  • Detent and spring pressure keeps sight erect but allows for unobstructed folding under impact, etc.
  • Compatible with most MIL-STD-1913 Picatinny / STANAG 4694-railed hand guards* and provides the same height-over-bore as standard A2 irons
  • Made in the USA.



SPECS

  • Position: Front
  • Height above rail, stowed: ~0.51 in.
  • Length, deployed: 1.5 in.
  • Length, stowed: 2.6 in.
  • Weight, w/ hardware: 1.2 oz.



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.

Solid quality
First time I purchased a polymer sight.This went on my 9mm ar9 pistol that I use just for range plinking.The polymer sight is of good quality, easy to mount, easy to adjust.The adjustment key is also polymer.BTW, a "steel" adjustment key will no work on this sight.So...don't lose the polymer key that is included.I don't know how "tough" the sight would be under a range "run 'n gun" type of shooting where the firearm would get a lot of bumping and banging against wood and\or metal objects. ...Read more

Good budget front sight
This is a great budget front sight.It is not the BEST front sight out there by any means, but it is good enough for casual shooting or a budget build.
