What is the TANDEMKROSS - Ruger MK Series "Shadow" Picatiny Rail-Black?

The Tandemkross Shadow Picatinny Rail for Ruger® Mark series and 22/45™ pistols gives you greater flexibility in your choice of optic and in where you position it on your pistol. Eight MIL-STD Picatinny cross-slots give you plenty of leeway in positioning a red dot or other sight for optimal eye relief. Other features of the Shadow Picatinny Rail:

  • Cutout on underside minimizes risk of interference ejected shell casings
  • Shorter, trimmer & better looking than factory optic rail
  • Solid & secure - precision-machined aluminum, hardcoat anodized finish
  • Mounting screws included

Tandemkross designed the Shadow Picatinny Rail so you can install it on your Ruger® Mark series or 22/45™ pistol without removing your gun’s "iron" sights. With a quick-release mount on your optic, you can switch back to shooting with iron sights in seconds. The Shadow Picatinny Rail fits factory drilled and tapped receivers on the following Ruger® .22 LR pistols:

  • 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
  • Mark IV™ 22/45™ Lite

Gives me more versatility than the factory mount
Gives me more versatility than the factory mount as it takes picatinny rings. Fits fine, leaves a bit of a lip under each side, but the part of the base that is radiused fits the frame perfectly.

Installed on Mark IV 22/45
Installs easy, but strongly recommend going heavy on the loctite (similar to front sight post on the Ruger Mark series). It tends to loosen up while shooting. Mounted a Romeo5 on my Mark IV with this, and other than the screws backing up a bit, it worked wonderful. Went heavy on the loctite to see if that resolves the issue, but it fits really well on the 22/45 (non-lite version) and holds the red dot really well. As mentioned it does not hang over the barrel, has a cutout for the ejection port, and fits well. Zero issues with casings ejecting during a 300 round range session.

Just right
I replaced an older, non-picatinny rail on my MkII with this, and am happy with it. This rail fit well, was easy to install, and looks good. As mentioned, it doesn't overhang the front of receiver like my old rail did. I'm using it to mount either a pistol scope or a Burris FF3. No problems so far. At first I thought the use of screws instead of allen bolts for mounting was an issue, but realized that allens would be overkill, and probably too easy to over torque. Overall I'm very happy with this upgrade.
