I find the length of pull about 1/2" - 3/4" too long on my Axis.

Has anyone cut the stock down on their Axis and re-attached the recoil pad? I can't tell how the pad attaches, don't see any screws. Would it be easier to cut it down and then put on a Slip-On pad?

And what is that square hole on top of the stock 1" from the end of pad?
