There is no best gun, certain people play better using a certain gun where others don't.
It also depends on the style of the player, if you are a player that rushes to the enemy territory then a sniper would be pointless. Where as if you was a player who played in there own field picking off the long shots of people moving about then a sniper would come in handy. Shotgun is the opposite to this and the other guns are more for middle range.
Personally i use these guns as my main:
M4 Carbine
AK-47
P90
MP5
I think they are all very good guns.
The best gun wold have to be the P90 Silenced with USP and RPG, Stopping Power and Extreme Conditioning But you may think different...............
a ak47 with gernade launcher
I think you mean kalishnagov.
depending on the gun, there is different challenges for the gun, (10 headshots, etc.)
The best gun that is fully ato and almost no recoil is the AK-74 with silencer and if you use over kill with 50.CAL claymores and iron lungs AK-74 silencer
This would really be an opinion, but it depends on what you are looking for. For example, a .50 cal sniper is good for longrange, or ak47 for a good machine gun.
The easiest gold gun to get is the gold desert eagle, you reach it when you turn to level 55.
its has gold guns and it is the best THE BEST
Who is the Best at COD4 is a matter of opinion. If you own COD4 just go online and check the leader board. Depending on what console you own it on will produce different results.This question has now been protected due to repeated vandal attacks. This is the most neutral, balanced answer.
