You saw it in my DLC thread... but for anyone else who happens upon this thread looking for info-
Maverick will be (2) weapons in the DLC - one assault rifle and the other a sniper rifle. Details are available here:
It seems like the Maverick sniper rifle is meant for CQC. Just take a look at the amount of zoom and how fast it is to raise the gun.
I predict it will be the quickscoper's choice.
