The Ruger Stock Module (part no. 90433) 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 compact 12.5-inch length of pull for smaller-framed shooters or those running heavy outerwear. It’s a direct, tool-free swap on any compatible Ruger American stock.
