Call of Duty MW2 class setups and camo help.?

I don't really like the M16 but it works really well for some people. If you are one of those people then go for it. The rest of the guns are great. Try the Scar in place of M4. It seems to work better in my experience. The FAL is a really good alternative as well. Powerful and accurate as long as you don't mind the single shot.
