Original price was: $94.99.Current price is: $89.99.


The next evolution in the Magpul MBUS (Magpul Back-Up Sight) line, the MBUS 3 incorporates the best features, strengths and value of the 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 0.44” high when folded and 1.15” at its widest point. Its aesthetics are derived from the MBUS Pro, but the MBUS 3 Front and Rear Sight is constructed of Magpul’s impact-resistant polymer, making it lightweight and extremely durable.

Featuring the same spring-loaded technology as its predecessor, they can be deployed with an ambidextrous push-button. The MBUS 3 sits at standard AR-height when deployed.

The MBUS 3 Front Sight includes tool-less elevation adjustments and a dual width enhanced front sight similar to the MBUS Pro.

Made in the USA.
