In multiplayer it's an RPG-7 cause you have to unlock it at level 80 and thats the highest. In my opinion, my fav is a custom. A G36C with an ACOG sight and a grenade launcher. The most preferred is an AK-47 with a red dot sight. Thats all I got to say.
It is very hard to answer what are the best guns in MW3, as it is all a matter of opinion and gaming style.
If you are a full action assalt person, I recoment the G36C for its mobility, and just about any submachine gun especially the MP7. But if you are a camper (I don't like you), you should use the AS50, or the MSR for its acuracy. And if you spray alot, or find you need to reload too much, use the P90. And if you have good accuracy in close combat situations, but your gun doesn't seem to kill anyone, I would recoment the model 1887, but if you haven't unlocked it, any shotgun is good.
It is kind of obvious that the higher level weapons are the best e.g. the MSR, the striker and the model 1887, the FAD, and the MP7. So here are a list of the overpowered guns at the level you unlock them.
They are the weapons, I think are the most overpowered, but please improve my answer, if you think otherwise.
And do the community a favor, don't use the Type 95, MK14, or the RPG-7, because it annoys everyone.... ...Especially me.
Acr/fad/type 95.
The best mw3 gun is the L118A but that's because I like sniping.Or if you put the first one on perk 2 its the best quickscoping gun
mw3 is awesome very awesome for awesome people and this stupid tf2, the gun suck, everything in tf2 is suckish. play mw3, mw3 is the best and tf2 are for noobs and losers
Of course, it is the best gun for close combat.Just put range and extended mag because it runs out of ammo fast.
G36c holographic and silencer. The best gun on my oppinion is the p90 with the silencer and rapid fire or acog scope and silencer.Its a pretty quick reload to.
i would say like the acr or p90 it depends. try every one and see witch is best
The clan is rhvg
farhaanbossman is the best at mw3
Either an M4A1 or M16
RSASS sniper rifle
you have a good gun and kill everyone you see. :)
The best sniper riffle on MW3 is the MSR but some like the ASSO.
Mp7. its the usp 45. Mk14 for long range. Msr for Sniping. Mp7 for close range. 44 magnum tac knife for BEST SEACONDARY.
