Mine is:
Primary: M21 Rifle. For some reason, some people don't spot ghillies too well, even tho you're running around. It's also a great weapon for mid-long range, to kill snipers etc (very low recoil).
Secondary: I have 3 setups.. one is Magnum/tactical knife, the one I use the most has Akimbo Rangers (pretty powerful from close distance, useful when you are facing more than one enemy) and the last one has the AA-12, which is my fav weapon in MW2
