The MBUS Gen 2 rear sight deploys from a flat folded position to a vertical aperture with a spring-loaded push-button, then folds flat when not in use to leave the primary optic’s field of view unobstructed. The aperture rotates to provide a smaller precision aperture and a larger emergency aperture for fast close-range acquisition. Windage adjustment is tool-assisted for zeroing to match the paired front sight. The MBUS Gen 2 rear mounts to any standard Picatinny rail and pairs with the MBUS Gen 2 front sight for a complete polymer BUIS set.
