Ultradyne C2 Offset Fldng Cmb Aprtr

The Ultradyne C2 Offset Folding Combo Aperture is a fully machined rear sight system engineered from 416 stainless steel and aircraft aluminum to deliver maximum strength without excess weight. This compact sight solution integrates dual aperture functionality—combining a ghost ring option with a dedicated .070 aperture storage integration—into a design optimized for modern tactical rifles and precision platforms where real estate and weight discipline matter. The rear sight features a positive-click oversized windage knob that serves dual duty as secure storage for the smaller aperture when the ghost ring is in active use.

The C2 combo system includes full windage and elevation adjustability on both front and rear components, enabling shooters to dial in precise zero without external tools. The dual-aperture design accommodates both close-quarters engagement profiles and longer-distance target work, allowing rapid transition between aperture sizes depending on lighting conditions and distance. At 0.31 lbs and measuring 4 x 1.25 x 9.25 inches, the folding geometry minimizes profile when stowed and maintains low-profile compatibility with common optic mounting systems. Material selection—specifically the combination of 416 stainless for corrosion resistance and aerospace-grade aluminum for weight efficiency—reflects the engineering approach Ultradyne applies across its sight lineup.

This aperture sight system addresses operators, precision rifle competitors, and serious sport shooters who prioritize mechanical sight reliability independent of batteries or electronic systems. The offset folding design integrates into modern tactical rifle setups alongside primary optics, providing a backup sighting solution that requires zero co-witness adjustment. Users working in variable lighting or transitioning between close and distant targets benefit from the dual-aperture configuration. The positive-click windage mechanism and integrated aperture storage reduce fumbling during gear transitions and eliminate the risk of losing small components during field operations.
