Ruger 90434 American Stock Module High Comb Compact LOP Synthetic Black

The Ruger 90434 American Stock Module is a synthetic comb module built for Ruger rifles equipped with the Modular Stock System, including the American Rimfire and 10/22. This High Comb / Compact LOP variant is designed for shooters running aftermarket scopes or mounted sights, raising the cheek weld so the eye lines up with the optic without a head lift.

Constructed from textured black synthetic, this drop-in module delivers a 1.84" comb height for proper scope alignment. The fixed 12.50" length of pull provides a compact, snug fit ideal for smaller-framed shooters, training rigs, or anyone preferring closer stock-to-shoulder geometry. With its fixed position and no adjustment hardware, this module goes in clean and stays put.

Swapping modules is quick; drop the 90434 into any Modular Stock System Ruger rifle to immediately change comb height and length of pull. Whether you are dialing in a rimfire trainer or running a 10/22 with a red dot, this Ruger 90434 stock module offers a factory-original route to a personalized fit.
