The Ruger Stock Module (part no. 90431) is a low-comb cheek piece built for any Ruger rifle running the Modular Stock System, matching the stock’s comb height to standard iron sights instead of a scope. Ruger sets the comb at 1.26 inches for correct eye alignment with the sights, and pairs it with a standard 13.75-inch length of pull sized for a typical adult frame. It’s a direct, tool-free swap on any compatible Ruger American stock.
