Upgrade your rifle setup with the Cadex Defense Arca Lock Rail M-LOK for the X-Series, a precision-engineered Arca Elite System rail built for confident stability in the field or on the range. Designed for the CDX-R7 XS, X-LITE Series rifles, and the Strike XS chassis, this M-LOK rail attaches directly to the chassis fore-end tube for a clean, secure fit. Machined from durable 6061-T6 aluminum, it delivers the strength you need without unnecessary bulk, helping maintain a balanced feel during shooting and transport.

Built to ARCA-standard dimensions, this rail makes it easy to use supported tripods and support systems for a fast, dependable lockup. Deep locking serrations provide a positive, non-slip connection under recoil and loading, while the flush-bottom design helps prevent interference with tripod clamping. Whether you are building a precision rifle for competition, hunting, or long-range shooting, this rail is designed to enhance control, consistency, and shooting comfort.
