Luger rifles ?

[Dwight Gruber]

So, are these just conventional reciprocating-bolt actions, no toggles?

On a related topic, I seem to recall a toggle-action semi-auto modification to the Springfield rifle. Its been a long time, so I don't recall if this was the Pederson device or another idea, I just remember seeing pictures of it the first time I was a gun collector, many years ago.
