Good guns in this game are MP7,P90, PP90M1, Acr, T95, Scar-L, M16(after buff) striker and Usas.. (not including snipers)...

Best gun probably is the Mp7..

the best gun to use on mw3 for me is the type-95 with a silencer and rapid fire, what is loses in range it certainly makes up for in close quarters combat, it is awesome, give it ago.

ACR 6.8--Suppresor and Extended Mags

Slight of hand or Scavenger Assassin,Marksman

Barret .50 Cal--Extended with Speed Proficency

whatever gun is in my hands

     I like this answer. Im the same way. I can adjust to pretty much any gun i choose. Either from my own classes or one that i pick up off the ground. This is excluding pistols, haha. Although, i do like picking up a pistol that has the tactical knife attatchment, from time to time.

Here is a few of my favorites:
