How does the stock fit otherwise? There is a easy and in expensive way to fix it if you need to raise the drop at comb. If the rasped area is rough you can add bondo or some filler and smooth it out to re establish the shape and bulk. Then you can buy and attach an adhesive comb riser. South west shooters supply has many of different measurements for around 20 to 30 dollars. The comb riser will help make for a better stock fit and hide the rasped area. This is of course that the stock other wise means little to you.
