You'll build up the thickness of the gun and eventually, you might not be able to work any kind of moving levers that slide across it (Selector switch on an M16 for instance). Also, a fresh layer of paint may not stick as well to a previous layer as it would if you were to sand that previous layer off. It'll also prevent the first thing that I mentioned from happening.
You should always sand anything down before you repaint it.
