This 2 piece Generation 2 MBUS sight set (Magpul Back-Up Front and Rear Sight) is a low-cost, colored injection molded, folding back-up sight set. Front and Rear included with front sight adjustment tool.

These are GEN2 Sights. Front and Rear included.

The MBUS Front Sight is adjustable for elevation and fits all mil-spec 1913 Picatinny rail equipped weapons, but is specifically tailored to the AR15/M16/M4 platform.

PLEASE NOTE: Front Sight 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 top rail.

The Rear sight incorporates the familiar dual aperture and is adjustable for windage and fits most 1913 Picatinny rail equipped weapons, but is specifically tailored to the AR15/M16 platform.

All colors are available:  Black, Flat Dark Earth (FDE),  ODGreen and Foliage Green.
