This interesting Swedish design, the "Snabb38", was adapted to at least one Norwegian Krag. Photos of this ultra-rare 6.5X55mm rifle are displayed on the Gunboard's Forums (Scandinavian rifles).

Gosh, I thought the U.S. Krag stocks were fragile!

Gas operated?  Why not, since we have seen one made into a slide action.  This is only one step further removed.  Load it with stripper clips.  Or devise a belt feeding mechanism.

Here's more pics. of the "snabb38".

Krags with stripperclip guides were made too, but the army only made few for testing. These used ordinary swedish stripperclips.

There's also a Krag made to take Hotchkiss MG strips in a museum in Norway. The action is quite different than an ordinary Krag
