From Foundations website:

Thank you for taking a look at our Gideon stock from our Hybrid line of Foundation Hunting stocks!

What we have is truly a Hybrid stock. We have taken what we have learned from our work with micarta over the past 10 years and set out to design a lightweight stock that takes one of the most significant things we are known for, the dampening (or dead feel) shooting characteristic of our micarta stocks, and achieve that in a stock with a target weight of 32 oz bare. Functional weight of the stocks (bipod attachment point, recoil pad choice, etc.) will puts them more in the 2.5 lb. +/- range depending on configuration. 

Why a Hybrid?

Carbon fiber provides the stock high elastic modulus and high bending strength while the Kevlar/aramid supplies excellent torsion and dampening performance and assures high impact strength. The hybridization of the two materials together results in significantly higher energy absorption than carbon fiber or Kevlar individually. Using this in conjunction with our micarta material has given us an extremely stiff, impact resistant stock with unique dampening characteristics. When you shoot it, you know it’s a Foundation – “it just feels dead.”
