What is the best gun?

I need a new gun and im waiting for your opinions until i buy it :S

The ones i like and have the most chance of getting are:
Scar Light
Scar Heavy
AWM
K-2

If you don't like any of these guns vote on Wasting 100k gp on crates :P

YOU GUYS MY FUTURE IS IN YOUR HANDS *thinks**I'm Screwed*

buy scar light, deagle, flashbang, smoke nade
then use up the gp on aug camo or tommy gun gp crates sh$t

The gun I recommend would have to be the Scar Light, It has really good accuracy, the recoil is really low, and it has lots of power.
