High Tech makes some of the lightest..Rimrock by Borden are also light and extremely strong as well as Mcmillan which tend to be heavier 32oz. Depends on how much weight you want to lose off the rifle. Mcmillans are solid glass with foam in the buttstock and the inletting is CNC machined. They still have to be glass bedded although they advertise drop in. Same goes for Rimrock. The High tech has foam in the buttstock and in the foreend. All are extremely strong and stronger then any wood stock. Like I said before it all depends on how much weight you want off the gun or in the case of looks the style. Mcmillan by far makes more styles then the other companies and will CNC certain barrel contours and triggerguards whereas the others will not. If your interested in a beautiful walnut laminate look at a serengeti stock. If you want beautiful walnut and want a an aluminum bedding block that is extremely stable look at accurate innovations. HS precision makes strong stable stock as well but they weigh more then the others and they feel like a club in my hands. Bell and Carlson is at the bottom of the food chain, they make a reasonably priced Fiberglass stock but they tend to be heavier then most unless they make a special run for one of the major manufacturers ie Remington Titanium,Weatherby Fibermak,Vanguard.
