Magpul's MBUS 3 sights are the next evolution in the Magpul Back-Up Sight lineup. The MBUS 3 combines the strength and value of the original MBUS with the aesthetics and profile of the MBUS Pro. Significantly reduced in size from the MBUS, this front sight 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 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.
