The new MBUS (Magpul Back-Up Sight) GEN 2 is a 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.
NEW Features for GEN 2: Reduced size for greater optics compatibility. Spring-locking front sight post holds consistent elevation. (For Real Fire-Arms) NOTE: Cannot be mounted to a railed gas block due to excess heat issues.Front MBUS must be mounted to a railed fore end on the same plane as the receiver rail. Because of this the sight is also not compatible with MOE Hand Guards.

Lightweight reinforced polymer construction.
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.
