Magpul MBUS 3 Rear Sight – Flat Dark Earth

MAG1167-FDE -MBUS Value Meets MBUS Pro Features

The next evolution in our MBUS (Magpul Back-Up Sight) line, the MBUS 3 incorporates the best features, strengths, and value of our original MBUS and MBUS Pro Sights in a feature-packed back-up sight system.

Significantly reduced in size from the MBUS, it sits at just 0.55” high when folded, 1.38” at its widest point, and weighs a scant 30 grams with hardware. Its aesthetics are derived from the MBUS Pro, but the MBUS 3 Rear Sight is constructed of our impact-resistant polymer, making it lightweight and extremely durable. They have the same spring-loaded technology as its predecessor, so they can be deployed with an ambidextrous push-button.

WHEN DEPLOYED, the MBUS 3 Rear Sight sits at standard AR height and includes a windage adjustable, rapid-select aperture system.
