Magpul - MBUS® 3 Sight – Rear, Various Colors

MBUS Value Meets MBUS Pro Features.

The MBUS 3 Rear Sight is the next evolution in Magpul’s MBUS (Magpul Back-Up Sight) line, combining the best features of the original MBUS and MBUS Pro Sights into a versatile and lightweight back-up sight system. Significantly smaller in size than the original MBUS, it measures just 0.55” high when folded and 1.38” at its widest point, weighing a mere 30 grams with hardware.

It deploys with ambidextrous push-button functionality, sitting at standard AR-height when flipped up. Additionally, the MBUS 3 Rear Sight features windage adjustment and a rapid-select aperture system, offering quick and precise sight alignment for any situation.
