That's really bizarre. I bought a .243 ADL three years ago, and there's no way you could flex the stock by hand. I also bought one of Remington's synthetics to replace the laminate that I had on my .30-06 ADL (The laminate is just too pretty to carry around...). I don't think you could flex the stocks if you put one end in a vise and pulled on the other. You sure you weren't looking at a 710?
