Since the Chinese has a spike bayo vs. the Russian blade type. the channel/grove in the Chinese is longer and a bit more shallow.Also that front portion of the barrel that holds the upper and lower stock together has a notch on the botton, the Chinese may need to be ground out a bit for the blade to seat properly ,as well ,the groove in the Chinese may need to be made deeper.
A bit of work and she should fit ok.
