have to say the m4 is my choice of gun with a red dot

and have folling perks on
bandiloader (extra ammo)
stopping power (better bullet damage)
deap impact (deeper bullet penetration)
1 flash
1 frag

this means i can shoot throu walls and stuff and this really winds pepes up

i also like the mp5 for smaller maps as gizmo said it good fro from the hip fireing

i also like to use the eve drop perk when playing 1 vrs the rest as if your beening carfull you here the other when close and this helps and is funny when you here frengo going o FXXK when you have just sent a frag his way
