I had the same trouble and tried many things. The problem was not that I had upgraded the rifle, but what I was shooting at. What finally worked was to kill two different kinds of enemies with one shot, specifically a cycloid and a striker, which I did on the "Let the Light Shine Through" Challenge. The program is particular about the award; I think it took me a couple of kills in that combination before I was awarded that skill point and trophy (and several others, since it was the last skill point I earned). I should note that I had no mods on the rifle at the time.

The best way to actually get the skill point is to add the electricity mod to the weapon, in addition to firing at a larger group of enemies. For a while I too thought there was something wrong with the skill point, as shooting three or four of those smaller enemies at a time was not working. It was only when there were a larger number of the same smaller enemy type that the skill point finally registered. Maybe something's off with the counter?
