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, 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 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 Rear Sight sits at standard AR-height when deployed and includes a windage adjustable, rapid-select aperture system.
