Compatibility notes:

  • Silencer Shop recently released a branded version of the Ruger Mk IV 22/45.  This pistol has the mounting holes in non-standard locations.  Make sure you select the Silencer Shop edition version of the mount from the dropdown if you have one of these pistols.  The Silencer Shop version has 4 mounting holes in the top of the receiver. My mount uses two of these holes, spaced 2.758″ apart, leaving one hole exposed.  The standard Ruger pistols have 3 mounting holes, and my mount uses the two spaced furthest apart at 2.5″.  You might also want to check out the set screws available on the Assorted Screws page if you want to plug the exposed hole left by the original rail.
  • Ruger recently released a model number 43949 pistol with a unique vented rib top rail.  The standard version of my mounts (not the Silencer Shop version) are compatible with this model.
  • Vortex Venom users:  The mounting screws that come with your optic are too long, you’ll need some from our Assorted Screws page

Shield RMS vs Sig RomeoZero mounts:

The Sig RomeoZero optic is compatible with both of these mounts, but the Sig RomeoZero version of the mount is being discontinued.  The Shield RMS mount is an updated version that is compatible with a larger variety of optics, including the Holosun 407k/507k.
