You would need to convert the .473 bolt head you have that fits 308 cases to a .378 head that fits 204/222/223 cases.

You'll also need to either strip your existing bolt head and put the items on your new .378 bolt head, or buy the items separately and install them, allowing you two complete bolt heads.

You also might want a new extended baffle, though it isn't necessary; I found out that with CDI bottom metal and an AICS 223 magazine you must have the "standard" baffle as the bolt won't go back far enough to pick up a round in the magazine the the factory extended baffle.
