Ruger 90432 American Synthetic Black High Comb Stock Module with Standard LOP

The Ruger 90432 American Synthetic Black High Comb Stock Module is a direct-fit replacement for shooters running optics on their Ruger American Rimfire, 10/22, or any other Ruger rifle equipped with the Modular Stock System. If you've mounted a scope or aftermarket sight and found yourself craning your neck or getting an awkward cheek weld, this high comb module solves that problem by raising your head position to align naturally with your optics—no more head gymnastics to get a clean sight picture.

The synthetic construction is built to take a beating. It's lightweight, durable, and resistant to weather and solvents, so it'll hold up whether you're running drills at the range, hunting from a bench, or toting your rifle through wet conditions. The black finish matches standard Ruger rifle aesthetics and pairs well with modern tactical setups.

This module ships with a standard length of pull (13.75 inches), which works for most shooters but is worth measuring against your own rifle if you're between sizes. Ruger's modular system means swapping stocks is tool-free—just align and lock in. It's a factory genuine accessory, so fitment is guaranteed if your rifle runs the Modular Stock System.

Frequently Asked Questions

What rifles does this stock module fit?

The Ruger 90432 fits Ruger American Rimfire, 10/22, and any other Ruger rifle equipped with the Modular Stock System. Make sure your rifle supports the modular system before ordering.

Will this high comb work with my scope?

Yes. The 1.84" comb height is specifically designed to raise your cheek position for proper eye alignment with mounted scopes and aftermarket sights. This eliminates head position adjustments and gives you a more natural, repeatable cheek weld.

Is 13.75" the right length of pull for me?

Standard length of pull is 13.75 inches, measured from the trigger to the rear of the stock. This fits most adult shooters comfortably, but if you're particularly tall, short, or wear bulky clothing regularly, you may want to measure your current setup or compare against other LOP options.

How do I install this module?

The Ruger Modular Stock System is tool-free. Simply align the module with your rifle's stock attachment point and lock it in per Ruger's instructions. No gunsmithing required.
