The McMillan Edge is the default answer for a lightweight quality stock. But they ain't cheap, $518 if you order from here last time I looked.
If you are handy you can order a stock blank and finish it yourself from
www.hightech-specialties.com for under $300. I've done a couple. It ain't rocket science and they turned out OK for a working rifle. If you are anal about perfection, by the time you pay someone to profesionally finish one the McMillan ends up cheaper.
If bad weather isn't a concern the factory walnut stocks are not much heavier than synthetic. Much lighter than HS or B&C would be.
