Guys been thinking about the MCS-T4 stock for my 243 (or I should say my son's). Anyway, just wondering whether to go with the fixed vs. adjustable. Obviously the adjustable one is a bit more. What I would like to know is for those with the adjustable cheek piece, how many of you actually need to adjust that to get a better cheek well? I have the adjustable cheek piece on my AWs, but I have never ever used it. So, I am just trying to save some money that's all. Thanks for your help.
