Re: scope it or modify stock?
The stock positions your head, so that looking through the rear sight has you looking at the bottom of the front sight?
Bottom of the blade, or bottom of the ramp? If bottom of the blade, I'd suggest a lower ramp. Changing the sight would be easier and cheaper than modifying the stock, and would probably look better.
