The point is, that anything past 5,000 is kind of superfluous...besides which, what sort of magazine storage do you have? With the SAW and MAG box mags, you can carry multiple magazines and deploy them quickly. I was the Assistant SAW Gunner at LCV for our squad and the SAW was reloadable in about 25 seconds. In the end, the SAW will be realistic and the M4 with the box mag is for gamers.
