If you do have the head of the stock fixed, take a look at this link and read about the preferred method to fix it; it is an invisible repair. Some gunsmiths will want to drill and pin the split but that really looks soooo obvious. Fine a gunsmith that will do it so it is invisible and you will be much happier with the results!
