PLEASE NOTE: We are working on a photo of the Magpul MBUS in their Dark Earth color. In the meantime we have used the picture of the black model for illustration purposes.

The MBUS (Magpul Back Up Sight) is designed as a low cost folding back up iron sight.

Ambidextrous spring-loaded mechanism is extremely intuitive and positive.

In the lowered position, it fits under most EOTech and Aimpoint magnifier setups.

The MBUS fits all Picatinny rail equipped weapons, but is specifically tailored to the AR15/M16/M4 platform.

Dual aperature, adjustable for windage.
