The Magizine feeding problem is pretty common with Savage 93 series. The problem is in the metal piece that the magazine slides onto, It needs to be belt forward just a little bit. This needs to be done out of the stock and done very gentle, although it will take some force to do.
As for the sight problem, I've never heard of that happening before (but that doesn't mean a whole lot), that maybe something to ask your local gunsmith about or call Savage and ask them.
