The MBUS 3 Rear Sight is the next evolution in Magpul's sight line, offering a blend of the best features from the original MBUS and MBUS Pro, with a compact size and impact-resistant polymer construction.
It features a rapid-select aperture system, is 0.44” high when folded, and achieves standard AR-height when deployed, with ambidextrous push-button deployment for ease of use.
The sight is designed for attachment to M1913 Picatinny rails and is made in the USA, available in Flat Dark Earth color for AR-15 style rifles.
