The Magpul MBUS Back-Up Rear Sight in black is a combat-proven auxiliary sight system designed for tactical rifle platforms where primary optic failure or battery depletion demands immediate recalibration. This rear sight provides a reliable secondary aiming solution when your primary optic goes dark, making it essential for military and law enforcement units.
Engineered with a spring-loaded flip mechanism, the MBUS rear sight deploys with positive mechanical feedback and locks into position with audible and tactile confirmation. The precision-machined sight aperture and U-notch design ensure repeatable accuracy, making it effective at intermediate to extended ranges. Its durable polymer construction resists impact and corrosion, while the black finish minimizes glint.
Professional operators and serious civilian shooters mount the MBUS rear sight on picatinny rail systems as an always-ready backup to optics-dependent rifle configurations. This sight is particularly recommended for AR-15, AR-10, and other Picatinny-equipped rifles, providing a practical solution for dynamic environments.
