Nice guns, best used in less condensed, bigger areas. I personally like the MTAR21 or FAMAS (both take a little getting used to) or you could go with the infamous AK-47. The AK is good because it requires mild skill aka spary and pray. Nine times out of ten you get your target. The only downside is I think you have to acheive the rank of Master Sergeant to be able to unlock it.
