It is so easy to make a taller '03 front sight blade
Look through your junk drawer, part box, tool box, whatever, for a piece of steel the same thickness as your front sight. I used a shelf bracket for mine. If you don't have anything at home, take the sight blade with you to the hardware store and match up the thickness with something cheap but fairly rigid.
Lay your front sight blade on it, then trace it out with a Sharpie marker. Now, redraw the blade at the top so the rear edge is higher. Adjust the contour at the front to match up smoothly. Cut it out with a Dremel using a cutoff wheel (A vice grips is helpful to hold it). Match up your original sight again so the bottom lines up, mark the hole, then drill it.
Install the new sight on your rifle. Bring it to the range with a file. Shoot some groups and file down the top of the blade until you are at the desired POI. Remove the sight, degrease and paint it flat black (to prevent glare).
