About This Ruger Mark IV Midmount

Armadyne Ruger Mark IV Midmounts fit pistols with the standard three-hole receiver pattern. The Midmount spans the ejection port and moves the optic farther rearward while maintaining 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.

How the Midmount Position Differs

Standard mounts sit fully ahead of the ejection port. The Midmount uses the threaded hole immediately ahead of the ejection port and the threaded hole behind it, allowing the mount to span the port. Choose the version that matches your optic footprint.

Installation Notes

Unload the firearm and remove the factory rail or other mount. Secure the Midmount with the supplied two #6-48 x 1/8 flat-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.

There were no specs on the thickness and the pics were hard to tell given there were no sights to compare to so I was left wondering just how low it would be. Shipping through usps was terrible so maybe switching to a different carrier would be better. It finally showed up almost 2 weeks later and I could not be happier! It is amazingly thin and low. Approximately half the height of the rear sight on a Mk IV tactical. One of the reviews mentioned it didn't sit centered and there is potential to sit a little one side or the other but if you pay attention it's not hard to get it centered. Sight acquisition has improved tremendously, although it was super high on a picatinny rail and adapter. I have to be honest and say I wanted the Lobos but it was out of stock and I couldn't wait. I think I like this better than the Lobos! Great finish and machining. I hope it let's me attach photos.

The mid mount is made of quality material and looks great. the customer service was great as well. I made a mistake with my order and they made it very easy to return and reorder the right mount. Great products, Great customer service.
