Just to be clear, do you mean a composite stock that has and adj. comb and a built in recoil reducer...or, a composite stock with adj. comb and no recoil reducer, or what exactly. It will make the question easier to answer. I believe there is at least one company that makes a composite stock with adj. comb, but no recoil reducer. I have one of the Shooters Emporium stock and have been quite happy with it.
