The NcStar MARDRS AR-15 Rear A2 Backup Iron Sight delivers reliable aiming capability when primary optics fail. This flip-up backup sight features dual aperture settings for versatile shooting applications across different ranges and lighting conditions.
What Makes This Different
The MARDRS incorporates a traditional A2-style dual aperture system with modern flip-up convenience. Unlike fixed rear sights, this unit folds completely flat when not needed, preserving a clean sight picture through primary optics. The dual aperture design provides both a large peep hole for close-range work and a smaller precision aperture for extended distances. Spring-loaded detents ensure positive lock-up in both deployed and folded positions.Key Features
