As RC20 said, check out Boyds. Their laminate stocks usually weigh in at about 3 lbs. give or take a few ounces. They are both much heavier and sturdier then the accustock, (especially if you haven't filled in the hollow butt stock with weight of some kind).

If you're going to use it as a carry hunter I would suggest some stippling on it, as the stocks can get a little slippery when they get wet. I have a prairie hunter and Pro Varmint both. The Pro Varmint being my favorite of the two.
