Cadex Arca Elite System Full Kit AES-PRK419 is a precision accessory designed to deliver a secure, rock-solid interface for compatible Cadex platforms. Built for the CDX-R7 LCP/FCP rifles and Lite and Field Competition chassis, this rail kit combines a precision-machined 6061-T6 aluminum rail with stainless-steel locking pins for confident engagement and dependable stability. The Arca Elite System is engineered to match RRS standard ARCA rail dimensions and features deep locking serrations that help prevent unwanted movement, even during demanding use and recoil.

For shooters who demand fast setup and consistent performance, the adjustable tension clamp and quick-throw lever make attachment and removal efficient while maintaining a tight hold. It is a practical upgrade for precision rifle applications where repeatable positioning and a non-slip lockup matter most. The streamlined design offers the durability, fit, and control expected from Cadex accessories, making it a smart choice for users building a competition-ready or field-capable platform.
