Checkmate has some long sight lines from on top of the tower to the other side of the map.
The map with the hotel, swimming pool and marina has some long sight lines too, I forget the name.
Another map with a name I can't remember was the map in the shopping mall where you can shoot from the balcony above the arcade to the food court.
As well as Armada, shooting from the bridge to the front or back of the ship or vice versa.
The more I think about it, the more sections of long sight lines come to mind, not all would give you over 100m, but with some imagination, patience, and good luck, you're sure to find them.
Diesel and the drive in are good for farming the long shots. Even Nuketown has a decent spot on the far sides. Standoff, Cartel, WMD, Jungle, Garrison are also good maps for this. Most have a decent area to do the long shots.
Armada and Satelite are currently out of rotaton. I like Armada, never liked Satelite.
