Ultradyne C2 Front/rear Aperture

The Ultradyne C2 Front/Rear Aperture sight system delivers precision optics engineered for shooters who demand both accuracy and adaptability. Built from 416 stainless steel and aircraft aluminum, this dual-aperture configuration provides the versatility of switchable sighting options without the weight penalty that compromises handling. The rear sight features a positive-click windage knob with integrated aperture storage for the .070-diameter ghost ring, allowing shooters to transition between aperture sizes based on lighting conditions and engagement distance.

Both front and rear sight elements offer independent windage and elevation adjustability, enabling precise zero establishment and compensation for ammunition variance. The compact design—dimensioned at 9 inches in length and weighing just 0.25 pounds—minimizes sight radius loss while maintaining the mechanical advantage needed for repeatable adjustments. The combination of stainless steel primary components and aluminum construction delivers corrosion resistance critical for duty carry or field use while keeping overall package weight negligible. The machined construction tolerances characteristic of Ultradyne USA ensure positive click detents that hold zero through recoil cycles.

This sight system is purpose-built for shooters operating in varied light environments—patrol officers transitioning between indoor and outdoor spaces, precision rifle competitors, or trained civilians running modern rifle platforms who prioritize iron sight redundancy. The dual-aperture design accommodates different shooting distances and lighting without accessory swaps; the wider ghost ring improves target acquisition in low light, while the smaller .070 aperture delivers precision at distance. Operators who value mechanical reliability independent of batteries or electronic systems will recognize the C2 as a refined alternative to single-aperture fixed sights.
