Magpul MBUS Gen 2 Flip-Up Rear Sight – Stealth Gray
The MBUS (Magpul® Back-Up Sight) is a low-cost, color injection molded, folding back-up sight. The dual aperture MBUS Rear Sight is adjustable for windage and fits most 1913 Picatinny rail equipped weapons, 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 rail 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
