How long to you expect that rifle to last?
Your lifetime...perhaps beyond to your children's lifetime...
Guns can be wonderful investments and heirlooms or common disposable tools.
If you plan to treat it like a leaf blower, I don't see the point in the spending the extra cash on fancy wood...if fact, get the ugly black plastic stock and save even more money.
If you want to plan to keep if for several decades, that is only a few bucks extra amortized over years for something a lot prettier that will encourage you to take better care of it.
