The Magpul MBUS 3 Rear Sight is significantly reduced in size from the MBUS sitting 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 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 rapid-select aperture system.
Made in the USA.
