So I saw Ranger412's post about his stock modification.

I've been thinking about getting a choate for my 110. My first question is, is the butt end of the stock completely hollow? (If someone could post a picture with the recoil pad removed, that'd be great.) Or would a modification such as Ranger412's be possible?

Second question. If it is completely hollow, does anyone have an estimation on how much weight it would add to the stock if I filled, maybe not completely full, but the top and bottom of the stock with devcon? Enough I could put a butt hook and adjustable cheek piece.
