Ruger 90434 American Synthetic Black High Comb Stock Module with Compact LOP

The Ruger 90434 American Synthetic Black High Comb Stock Module with Compact LOP is a factory replacement stock designed for shooters running optics on their Ruger rimfire and .22 LR platforms. If you've mounted a scope or red dot to your Ruger American Rimfire, 10/22, or any other Ruger rifle equipped with the Modular Stock System, this high comb module solves a common fit problem: getting your cheek weld positioned so your eye naturally aligns with your sight picture. The raised comb lifts your face higher on the stock, eliminating that awkward head-lifting habit that kills accuracy and comfort.

Built in tough synthetic material, this stock module is built to handle field use without the weight and maintenance of wood. The compact length of pull keeps things proportional for shooters who prefer a shorter reach to the trigger—particularly valuable for younger shooters, smaller-framed adults, or anyone running tactical gear or heavy outerwear. At 12.5 inches, it's a significant drop from standard rifle dimensions, making this an excellent fit for precision .22 work or casual plinking where you want a snappy, responsive platform.

This is a genuine Ruger factory part, not an aftermarket interpretation. If your current Ruger stock leaves you craning your neck to see through your optic, or if you simply prefer a shorter pull, this module swaps in seamlessly on any Ruger rifle using their Modular Stock System. It's the kind of upgrade that doesn't change how the gun shoots—it just makes shooting the gun feel natural.

Frequently Asked Questions

Will this stock module work with my Ruger 10/22?

Yes. The Ruger 90434 is designed to fit any Ruger rifle equipped with the Modular Stock System, including the 10/22 and Ruger American Rimfire platforms.

What's the difference between this and a standard comb?

This module features a raised comb height of 1.84 inches, which brings your cheek higher on the stock so your eye naturally aligns with mounted optics. Standard combs sit lower and require you to adjust your head position to see through a scope or red dot.

Is this module suitable for both scoped hunting and tactical shooting?

The high comb is specifically designed for rifles running optics—scopes, red dots, and similar mounted sights. The compact 12.5-inch length of pull works well for both hunting and precision shooting applications.

Can I use this on a Ruger rifle without the Modular Stock System?

No. This stock module requires a Ruger rifle equipped with the Modular Stock System to install properly. Check your rifle's manual or contact Ruger if you're unsure whether your model is compatible.
