Shoot it first at 25 meters to see were it impacts. It's not unusual for the front sight to not be centered when sighted in. It's likely a 7/64 " hex head cap screw on your front sight. Early USGI front sight screws took a 3/32 " hex head wrench.

I would call Springfield Armory, Inc. Customer Service and discuss the over-indexing of the barrel.

The front sight isn't hanging over the dovetail, and there is still enough room to move it over more if I so desired. I then dialed in 2 clicks left windage on the rear sight and she was hitting the bullseye at 50 yards prone.

As long as the front sight is not hanging off the base, it meets the military requirements. This is very normal for a M14 type rifle. IME, different makes of ammunition will cause the windage to shift a click left or right. FWIW and HTH
