Introducing the next evolution in our MBUS line, the Magpul MBUS 3 Back-Up Sights. Merging the best features, strengths, and value of the original MBUS and MBUS Pro Sights, the MBUS 3 offers a highly efficient and reliable back-up sight system for your outdoor needs. The MBUS 3 is significantly reduced in size from the original MBUS, sitting at just 0.44 inches high when folded and 1.15 inches at its widest point. Drawing aesthetic inspiration from the MBUS Pro, these sights are crafted from impact-resistant polymer, ensuring they are both lightweight and exceptionally durable. Features include the established spring-loaded technology of previous models, allowing for quick deployment via an ambidextrous push-button. The rear sight sits at standard AR-height when deployed and includes a rapid-select aperture system for swift target acquisition. Designed for durability and ease of use, the Magpul MBUS 3 Back-Up Sights are your perfect companion for any shooting excursion.
