Ultradyne USA C2 Folding Combo Aperture Sight – Precision Rear Iron Sight for AR-15 Platforms

The Ultradyne C2 Folding Combo Aperture delivers dual-aperture flexibility in a low-profile folding iron sight. Features both a precision 0.070" aperture for target work and a larger 0.200" aperture for rapid acquisition in defensive scenarios. The tool-free folding mechanism deploys quickly and locks securely, making it ideal for co-witnessing with red dots or as a standalone backup sight system.

Mounts to any MIL-STD-1913 Picatinny rail via a spring-loaded clamp mechanism that requires no additional tools. Precision-machined from 17-4 stainless steel with a corrosion-resistant black oxide finish. Designed for AR-15/M16 platforms and compatible with standard A2 height front sights. The low-profile design folds flat when not in use to avoid snagging on gear or obstructing optic housings.
