The MBUS (Magpul® Back-Up Sight) is a budget-friendly, colorful injection molded, collapsible 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.

  • 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
  • Made in the USA

All service and warranty issues must be directed to, Magpul.
