Far cry 2 multiplayer question

is it possible to unlock all weapons for a cirtain class, because it looked like you could only use three diamonds each. So for example if you use the 3 diamonds to buy the as50, could you still also get the dragunov?Far cry 2 multiplayer question
thats a good question...i would assume so, but why would you want to use one of the weaker guns if you purchased a better one?
