Best guns to use
Sniper: The 50cal. Is only the 2nd best in the game. I know it's powerful as hell but unless you are trying to hit a mofo through a wall at a mile away don't use it. The M21 is the best sniper you can use. Its fast ans quick reloading.
Assult Rifle: The Classic M4 carbine or if you have it the gold AK-47 these are both reliable and powerful.
Sub-machine gun: the AK-74u is the best one by far. It is just like the AK-47 but smaller.
Heavy machine gun: the Last one you unlock(dont remember the name.) It is powerful as hell as fast to shoot and reload.
Shotgun: the last one. Fastest shooting shoty and fast to reload.
I hope this helps because I've kicked ass with these.
