Probably a few others I'm not thinking ofr at the moment would have to be finished after casting. It would probably be VERY close to doing a "0%" after the casting. However, it could be finished with a drill press and a file! If it were me doing it I would put my alignment pins for the mold in the front and rear take-down pin holes and ream to spec. after casting. The mag well COULD be cast in but other than that....
So yes it COULD be do if you know enough about mold making. Could actually be a fun project.
