Ruger 90433 American Rimfire Stock Module Low Comb Compact LOP Synthetic Black

The Ruger 90433 Stock Module is a replacement comb piece designed for the Ruger American Rimfire rifle and other Ruger rifles equipped with the Modular Stock System. Built from durable synthetic material in a black finish, this module lets you swap out the comb section of your rifle's stock to fine-tune fit, eye-to-sight alignment, and length of pull without replacing the entire stock assembly.

This module is configured with a low 1.26" comb height, optimized for use with standard iron sights rather than high-mounted optics. The 12.50" length of pull offers a compact fit well suited to younger or smaller-framed shooters, as well as anyone who prefers a tighter, more upright shooting position. With its fixed comb design and textured synthetic surface, the module drops directly into the Modular Stock System for quick installation.

Whether you are customizing a Ruger American Rimfire for a new shooter, dialing in the comb for iron-sight work, or simply keeping a spare module on hand for different shooting scenarios, the 90433 is a straightforward, drop-in fitment part. Made in the USA by Ruger.
