Definately the M4A1. This gun owns. If you use it a lot, (like me

) you can shoot a perfectly straight line of fire, it owns. Just stand and make the crosshairs at upper chest and youll get em everytime. this gun is great for DG. If you can shoot a straigh line of fire and a terrorist is runin to or from the hostage building you can get a nic kill. I did that once, the guy got the hostages and i saw him and i shot a couple rounds and he died one of my fav kills.
