Ruger 90432 American Rimfire Stock Module High Comb 13.75" LOP Synthetic Black

The Ruger 90432 Stock Module is a drop-in rear-stock comb insert for the Ruger Modular Stock System, built to fit the Ruger American Rimfire rifle and equally compatible with the Ruger 10/22 and any other Ruger rifle that accepts the modular stock interface.

This High Comb configuration raises the cheek weld to a 1.84 in comb height, giving shooters the extra facial clearance they need to line up the eye properly with aftermarket scopes or mounted optics. The standard 13.75 in length of pull keeps the fit consistent with the factory stock, suiting most adult shooters without an additional spacer.

The module is molded from durable black synthetic with a textured surface for a secure cheek weld, and installs as a fixed, non-adjustable replacement comb - no permanent modifications required beyond the standard modular stock swap. It carries no integrated swivel studs or accessory rails, preserving the clean lines of the host rifle while letting the user dial in the correct sight-picture height for magnified glass.

Whether you are running a scope on a Rimfire and need the extra comb height, or simply want a spare or replacement rear module for a Ruger 10/22 equipped with the modular stock, the 90432 stock module is a clean, drop-in upgrade for the Ruger Modular Stock System.
