Magpul MBUS Sight - Front, Olive Drab Green

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.

Made in the USA.

• 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

  • Polymer construction provides light weight and resists operational abuse

• DETENT AND SPRING PRESSURE KEEPS SIGHT ERECT
