Especially so with the taller front sight blade of the 03-A3, with the sight protector on you have added another aperture for the eye to center, and it does. Only problem is that the front sight blade is not centered in the front aperture, and is very close to the top of the sight protector. You have to consciously disregard the front aperture, which is now in the way, and concentrate on the sight blade to keep it centered in the rear aperture.
If you want to try it for yourself, stick two round bit screwdrivers in the upper part of the sight protector and pry it apart as best you can to help get it over the sight, and have your best buddy there to help get it on. Coming off it removes some more finish. I have seen them with the folded over piece on the rear cut off to allow the protector to slide on instead of over the sight.
