Designed in collaboration with a local gunsmith, this rail mounts to the bottom of the barrel of your Ruger Mk. I, Mk. II, or Mk. III pistols. Installation by a gunsmith is required. See the Installation Instructions page for more information
Note that this only fits pistols that have the metal grip, and not the 22/45 models.
Two options are available: 1″ and .870″. Check your barrel diameter before ordering.
