I had put this out about a year ago now, but I believe that it's still valid for Crown, Streamline and Wildcat Gen I. There are minor differences between a Crown and a Continuum such as the barrel to receiver mount, lite barrel and shroud. Otherwise, I think that all of the same O-Rings are used.
I have been asking the same questions! I have a Continuum and would like to get a box of o rings for it and some extra parts, but I can only find stuff for the old style crown. Does anyone know if there is anywhere that sells parts for continuums?
