The ACR is a good upgrade from the SCAR if you don't have it already. Its unlocked at Lvl48. I haven't had much time to play lately so I'm only a 1st level Prestige Lvl 50 I believe. Most of my friends are already 2nd Lvl Prestige, one is actually 4th Lvl Prestige already. I obviously don't have as much time as they do. h:
