I hate to say it, but the op is vauge. He doesn't even know if it is a Mcmillan or factory tupperware. Do any of you even know if it is a fwt or std wt? Op does not say. Is it a winlite stock? Pics of the rifle and stock. Op is not going to know exactly what it is and you guys don't know what the stock weighs because the op doesn't even know wth he has. So the original question is impossible to answer.
