They aren't vanishing. If you've ever used or seen a real laser-pointer before, you would know that you can't actually see the beam. Only the source and the point it is hitting. The only time you can actually see the beam is if there is some sort of particles floating around that the light bounces off of. In the game, they show off the first bit of it to show the player that they are laser guided. However, your eyes can't actually see the beam itself, which is why it looks as if it 'vanishes' in front of it. Perhaps it would make more sense, logically, if the machine guns had some sort of exhaust port in front of the laser source that way there could be floating particles that allow us to see the beam near the source.
