The sniper rifle in the game is a fully black SVD Dragunov. Depending on where you hit, it is the most powerful rifle in the game. But since a lot of the game consists of close-quarters shooting, you barely get to use the SVD. The SVD is also a sniper rifle in 007: Legends. It has a 10 round magazine and is semi automatic.
The SVD Dragunov appears in the game as the V-TAK. The name comes from the film A View To A Kill. It can be outfitted with a night-vision scope, laser and suppressor.
