There hasn't been any Kevlar in a Kimber stock in a long time. Even when there was, it was a small amount in the recoil lug pocket. In addition, there's virtually no carbon fiber in the Costa Rica made stocks, probably less than 0.01%. The Montana, Mountain Ascent, Adirondack, Subalpine and Talkeetna stocks consist of a two-part polyeurethane foam core with an outer shell consisting of fiberglass and resin.
The best synthetic stock that Kimber offers is the one made by AG Composites that's used on the Open Range/Open Country 84M rifles. That has a lot of carbon fiber in it, i.e. the entire outer shell is made from a carbon fiber prepreg.
The Hunter stock is a 20% glass-filled polypropylene and it's one of the stiffest stocks available at that price point. The company that makes it also makes stocks for many of the big rifle manufacturers and they will tell you that the Hunter is the best stock they make.
Thanks for that information MCMXI.
I will admit to being slightly disappointed to learn that the Montana stocks are more fiberglass than kevlar. Do you know when they stopped with the kevlar in the Montana's?
