The next evolution in Magpul’s MBUS (Magpul Back-Up Sight) line, the MBUS 3 incorporates the best features, strengths and value of Magpul’s 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 0.47” high when folded, 1.38” at its widest point, and weighs a scant 25 grams with hardware. Its aesthetics are derived from the MBUS Pro, but the MBUS 3 Front 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 Front Sight sits at standard AR-height when deployed and includes tool-less elevation adjustment of a dual width enhanced front post similar to the MBUS Pro.
MBUS 3 Sights will be available in Black, Flat Dark Earth, and OD Green.
Made in the USA.
