It was convincing enough for the CO to have all school members do their annual qualification on the C7 in the simulated range instead of spending real ammunition. Being a pretty good shooter myself I found this exercise challenging and even if this simulation does not replace a real firearm (though it simulate the movement of the rifle when firing) and the weather conditions and wind that you would find on e real range, it is good enough to insure that if you would have to fire a real C7 after going through the simulation, you would do so accurately. My own experience on it convinced me of this fact.
