Ultradyne C4 7.62 Cal/.308 Cal Folding Sight Combo Front/Rear Flip-Up

Overview

The Ultradyne C4 Folding Sight Combo is a dual-aperture sighting system designed for 7.62/.308 caliber rifles, including AR platforms. Featuring an anodized black finish, this front and rear sight set utilizes a concentric circle-within-circle sight picture to reduce parallax, enhance clarity, and enable faster target acquisition. The C4 rear sight includes a ballistically calibrated elevation system adjustable in 50-yard increments up to 600 yards, rapid windage adjustments, interchangeable apertures (.70", .50", and a ghost ring), and a spare aperture stored in the windage knob. The C4 front sight offers tool-less concentric elevation adjustments and windage adjustability for zeroing. Both sights feature one-handed deployment and stowage, and are fully machined from a combination of 416 stainless steel and aircraft aluminum to maximize strength while maintaining a lightweight, compact profile.
