Description

The MBUS 3 (Magpul Back-Up Sight) is a low-cost, injection-molded, folding back-up sight. It is a further evolution of the original MBUS and MBUS Pro back-up sight system.

The new iteration is manufactured from impact-resistant polymer, making it lightweight and durable at the same time. It is reduced in size but does not mitigate the performance of the previous versions.

The MBUS Front Sight is adjustable for elevation. It fits most MIL-STD-1913 Picatinny-railed hand guards but is specifically tailored 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. 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 incompatible with MOE Hand Guards.
