Buy Whatever gun you want, If you want to buy a single shot bolt action .. go for it..
There are lots of well seasoned players here who have a lot of experience with the sniper role.. and weapons and upgrades needed.
However rather than trying to figure all this out by asking a lot of questions and getting a lot of conflicting answers.. Head out to a game and talk to the people you meet there who are sniping... they can offer real help in short order.
