I unlocked it on a couple of weapons in support and the engineer class. I'm now not to far off with the M14 (awesome weapon). It's hard going back and starting a new weapon and trying to unlock it again. I do like how you have to unlock it for each individual weapon, unlike BC2 where once you had it, it was available for every weapon.
