The flex thing has been overblown in my estimation. Unless you are using a bipod it should not be a problem. My black plastic stocked 7x57 has never been a problem with flex and shoots well under MOA. Under normal conditions you are never going to put enough pressure on the forestock to cause it to flex. I have tried to flex it enogh to cause inaccuracy under normal hunting situations and as far as I can see it just isnt a poblem. Plus, the accustock is very stiff and made that way. Go get that rifle and you will be happy.
