The Ultradyne C2 Flip-Up Aperature Front Sight packs all the high-quality features Ultradyne is known for into a lightweight, compact front sight. Fully machined from the perfect combination of 416 SS and aircraft aluminum to maximize strength and weight. Sighting in is a breeze with the fully adjustable windage and elevation knobs. The 12 MOA aperture gives the advantage of lightning-fast target acquisition while improving accuracy. Improved accuracy is created by the enhanced clarity and reduction of parallax due to the optical characteristics of the C2 dual aperture. In addition, the C2 enables the shooter to see 100% of the target, not cover it. This promotes proper shooting techniques and allows the shooter to focus on the only thing that matters, the target!
