MBUS 3 Front Back-Up Sight – Black

The MBUS 3 (Magpul Back-Up Sight) is a low-cost, injection-molded, folding back-up sight representing an evolution of the original MBUS and MBUS Pro systems. Manufactured from impact-resistant polymer, it is lightweight, durable, and reduced in size without sacrificing performance. The MBUS Front Sight features elevation adjustability and fits most MIL-STD-1913 Picatinny-railed hand guards, with a design tailored specifically to the AR15/M16 platform. Made in U.S.A. Note: The product cannot be mounted to a railed gas block due to excess heat issues and must be mounted to a railed fore-end on the same plane as the receiver rail. It is incompatible with MOE Hand Guards.
