About This Mount
This mount replaces the factory rear mount supplied on Riton-Equipped Ruger Mark IV 22/45 Lite models. It installs in the same factory mounting position and provides a direct connection for the selected optic footprint.
Compatibility
Confirmed compatible Ruger models are 43946, 43947, and 43948. These models were originally supplied with a Riton red dot and custom factory rear mount near the takedown button.
This line is only for the factory Riton rear-mount receiver pattern.
- For a standard three-hole receiver, choose from the standard Ruger Mark IV mounts.
- For a Silencer Shop Exclusive four-hole receiver, choose from the Silencer Shop Exclusive Ruger Mark IV mounts.
Installation Notes
Unload the firearm and remove the factory Riton rear mount. Secure the Armadyne mount in the same location with the supplied two #6-48 x 1/8 cap-head screws.
Attach the optic to the mount and dry-fit the assembly on the receiver before final installation. Confirm that no optic screw can protrude far enough to contact or scratch the receiver.
Follow the Ruger Mark IV installation instructions for the complete screw-length check, torque values, and optional thread locker adjustment.
