Playing the Russian beta right now (used up all my C2 activations), so do the basic attachments unlock after a certain number of kills? I'm the assault class and i'm tired of the iron sights, i've not been playing it much but i'm gonna start getting into it now.

Dunno I never managed to unlock any attachments -.- Just picked up some cool weapons from the ground lol.

Ok what happens is before each match you can either earn xp for equipment, gear, or weapons. Choose the one on the right. That will unlock things like new attachments for your guns. But beware, not every attachment works for every gun. You have to own the right gun to use and attachment. So far I've found that the daewoo k- whatever in the assault class uses a 3.5x and a 4x sight attachment. None of the lmg's use any other sights than the iron sights. In the engineer class the m-4 uses a reflex sight. That's all I've found so far.
