It appears to operates in a similar manner to the original M-1 carbine rear sight... but I agree that I don't see a spring to hold it in one position or the other.
Maybe there is a ball detent under the sight built into the dovetail?
Does the sight "click" into place when you flip it back and forth? or is it just "loose"?
