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.
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 not compatible with the MOE Hand Guard.
