Get Two triangular shipping tubes, about 38" X 6" X6". Then get 8X8X40 boxes from Uline. Put the stock in one tube and the fore-end in the other, with padding, and put the tubes back-to-back inside the Uline box. Put in bubble wrap or newsprint to secure the tubes inside the Uline box. You don't want them moving around. Pad one end so that the tubes don't slide. In four years of shipping this way I've never had any damage. I've probably shipped 300 guns this way.
