Mine is the G36C (I'm an addict)!

Draquav cause I am a hardcore sniper

ak47

M16 for the burst fire, its usually 1 burst 1 kill for me.

m16 is by far my fav

M16 or G3

Definitely the AK with iron sights.

M16!

MP44.

gotta be the m16!!

mp5

I go with the popular m16.

Carbine with my golden deagle.

ReTarDedFisHy's weapon of choice is the P90 (Red Dot Sight). He loves to go in and kick everyone's ass.
 
But for the bigger maps, he prefers the M16 (Red Dot Sight) for mid-range, and the Dragunov SVD (standard) for sniping.
Another one is the AK47 (ACOG Scope).

I absolutely love the G3. It's powerful and accurate...and oh so perty. The M16 is my favorite "beginners" gun and I use that until eventually unlock the G3...

Carbine, Sniper: M4oAG

The M16 is the overall most effective.  The G3 is the gun I have the most fun with.  The P90 does the trick on the levels I hate the most.

has to be Draquav i just love snipers

Still can't make up my mind between the AK & M4, I love them both.

Fav sniper is M40A3.

Fav Pistol is USP + silencer.

I find the M16 is a very efficient killing machine. But sometimes i would use a P90 or Mp5 depending on what map and what mood i am in.

M16

M16 is all you need with the right perks.

AK-47 with Red Dot Sight. I found that the auto fire helps in tight situations and it only takes a couple of shots to take someone down.

The M16 with stopping power is basically a one burst kill to the chest, I usually use it when I'm starting to fall behind.  I really have to play the game again.

M16 and .50 cal

ak47, I like it simple :)

P90 with a red dot sight, it has better range then you think and tears people apart close range.

Silenced MP5 - deadly!

M16 and Desert Eagle

M4

M 16 and G 36

M16 and AK-47

M16

 barret 50.cal ,m6,desert eagle, (C4 im addicted)

It depends but I mostly use the dragonuv if I'm sniping and the AK for everything else. I also use the shotty whenever Im looking for a change of pace.

M14 ACOG/silenced, M4 with red dot or M16 silenced.  Game type: hardcore TD. Perks: x3 special(flash), UAV jammer and deep impact.

m16, kind of cliche huh.

I like the M4. Its strong, accurate, and effective. Love it.

G3 Acog, with right perks you got a sniper rifle thats very effective at medium to long range

I don't play Call of Duty 4 anymore, but when I did, I was an M16 whore.

"Silenced MP5 - deadly!"

Either  m16 or gold ak47 depending on how cool I want to appear

MP5 is definately my favourite. I use RDS + fast reloading.

M16 FTW!

Rail Gun or Mantis Doll are definatly my favorite

Best assault rifle - MP44
Best sniper rifle - MP44
Best SMG - MP44
Best shotgun - MP44
Best Melee weapon - MP44

Damn according to this chart the MP44 just wins.
Good win there, MP44

Mine is the MP44.

MP5 , M16, G36c,

m4

Generally the G3, only in hardcore though. The MP5 is great in both hardcore and normal, M21 is a great hardcore weapon, but the best sniper is definitely the M40A3.
