It probably depends on the lenght of the shroud. I remember I did try if the shroud on a wildcat mk 2, would fit an impact with the same 500mm barrel lenght, it does not. the wildcat stock shroud is a litler longer than than impact shroud. But on the other hand a impact shroud will probably fit a wildcat, and maverick gun with same barrel length, as it will be a lilte shorter on thouse guns. It may not look that good though.
