The Tandemkross Shadow Picatinny Rail is designed for use on Ruger® Mark series and 22/45™ pistols. It offers more flexibility in optic choice and placement on your pistol. With eight MIL-STD Picatinny cross-slots, you have plenty of room to adjust your red dot or other sight for optimal eye relief. Other features include a cutout on the underside to reduce the risk of ejected shell casing interference, a shorter, trimmer design than the factory optic rail, solid and secure construction with precision-machined aluminum and a hardcoat anodized finish, and included mounting screws. It is available in Matte Black or Matte Gray to match or contrast with your gun's finish.

You can install the Shadow Picatinny Rail on your Ruger® Mark series or 22/45™ pistol without removing the iron sights. With a quick-release mount on your optic, you can switch back to shooting with iron sights in seconds. This rail fits factory drilled and tapped receivers on Ruger® .22 LR pistols, including the Mark II™, Mark II™ 22/45™, Mark III™, Mark III™ 22/45™, Mark III™ 22/45™ Lite, Mark IV™ Target, Mark IV™ Hunter, Mark IV™ Competition, and Mark IV™ 22/45™ Lite.
