Magpul MBUS Pro Back-Up Sight Rear

The Magpul MBUS Pro Back-Up Sight Rear is a rugged, all-steel folding rear sight built for dependable backup sighting when your primary optic is not in use. Its low-profile design stays out of the way when folded, while the deployed sight provides standard AR sight height with tool-less windage adjustment.

Built with a QPQ nitride finish for durability and corrosion resistance, the MBUS Pro Rear Sight attaches to M1913 Picatinny rails and uses positive detents to secure the sight, windage knob, and aperture window in position. The flip-up/down aperture gives users wide and narrow sight picture options for close-range, low-light, and longer-distance aiming references.
