About This Ruger Mark IV Mount
Armadyne Ruger Mark IV mounts fit pistols with the standard three-hole receiver pattern. They install on the two threaded holes ahead of the ejection port, placing the optic forward in a low-profile direct-mount position.
Direct mounting keeps the red dot closer to the receiver than a Picatinny or Weaver rail with a separate optic mount.
Compatibility
This line is for standard three-hole Ruger Mark IV receivers with two threaded holes ahead of the ejection port and one behind it.
- Ruger Mark IV 22/45 Lite models 43946, 43947, and 43948 use the Riton-Equipped Ruger Mark IV mounts.
- Silencer Shop Exclusive models 40179, 40181, 40182, 40186, and 40193 use the Silencer Shop Exclusive Ruger Mark IV mounts.
Standard vs. Skeletonized Mounts
Standard and skeletonized versions install in the same receiver location and use the same optic footprint. Standard mounts have a solid center that provides a continuous surface beneath the optic. Use a standard mount for any optic with a bottom-loaded battery.
On skeletonized mounts, material is removed from the center to reduce weight. Skeletonized mounts cannot be used with optics that have a bottom-loaded battery. Choose a top- or side-loading battery optic with the matching footprint.
Installation Notes
Unload the firearm and remove the factory rail or other mount. Secure the Armadyne mount to the two front receiver holes with the supplied two #6-48 x 3/16 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.
