MAGPUL MBUS 2 FRONT BACK-UP SIGHT ZWART

MAGPUL MBUS 2 FRONT BACK-UP SIGHT BLACK 

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.

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
