About This Ruger 10/22 ModMount
This mount includes the receiver-specific base and optic-side mount needed to connect your optic to a Ruger 10/22.
How the Two-Part System Works
The base fits the firearm receiver and provides the recessed oval ModMount interface. The optic-side mount carries the optic footprint and has a matching oval stud. Two flat-head M4 screws secure the two parts together.
Every ModMount optic-side mount works with every ModMount base. This makes it possible to move an optic-side mount between compatible firearm or rail bases. Learn more in the ModMount system guide.
Optional vertical and 45-degree offset spacers install between the base and optic-side mount to raise or reposition the optic. Spacers are sold separately unless otherwise stated.
Compatibility
This receiver base fits the four-hole receiver pattern used across all Ruger 10/22 variants and the discontinued Ruger .44 Magnum Stalker line. The front and rear receiver-hole pairs use different spacing.
Installation Notes
Unload the firearm completely. Remove the magazine, clear the chamber, and remove the factory rail or other mount. Secure the receiver base with the supplied two #6-48 x 3/16 cap-head screws. Seat the optic-side mount, or an optional spacer and optic-side mount, fully in the oval interface and secure the assembly with two flat-head M4 screws.
Attach the optic and dry-fit the assembly before final installation. Confirm that no optic screw protrudes through the optic-side mount far enough to contact or scratch the receiver.
Follow the installation instructions for the complete optic-screw check, torque values, and optional thread locker adjustment.
