Is the Skywatcher MN190 really 190MM?

Hi
Does anyone know if the Skywatcher MN190 has an oversize primary? I understand the corrector is 190mm, but if the primary is not oversize then my understanding is that will suffer reduced effective aperture. I've seen multiple reports that the Skywatcher Mak Cass variants all suffer from this.
