The new MBUS (Magpul Back-Up Sight) GEN 2 is a low-cost, color injection molded, folding back-up sight. The MBUS Front Sight is adjustable for elevation and fits most Picatinny-railed hand guard equipped weapons, but is specifically tailored to the AR15/M16/M4 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

NEW Features for GEN 2
* Reduced size for greater optics compatibility
* Spring-locking front sight post holds consistent elevation
