Tar-21, Intervention, M40, AUG, and of course the R700

You do know that, what is essentially a heavily modified R700 is in the game? Look up remington MSR.

On topic, only thing I will miss is the AUG, everything else that I loved is in MW3, either as good or better than they were (MP5 I'm looking at you!)

This is sad to hear

The gun that I will miss the most by far, the gun that I got a little sick in my stomach when Dr. Disrespect confirmed it himself to my face, the gun that I would shed blood to have back, the most Epic under rated gun of all time. I am speaking of none other than the monster known as the the F2000!!!!

yeah, I'm gonna miss it.

I am going to miss not having the M40A3 back from Cod4 - it was the best sniper of that game, why IW left it out of MW2 was mind boggling.
