Primary weapon: DSR 50 or Ballista.
Attachments: Laser and fast mag or extended mag
The reason I would say DSR 50 is because of the high damage because the one shot kill rate would be the waist and above excluding arms and hands and the reason I would recommend the Ballista is because of how fast it is and how accurate it is. Although I wouldn't call the damage on this sniper horrible but its from the chest up. I like the laser because on the hip fire accuracy increases which means you will probably aim more accurately. I recommend fast mag or extended mag because of the slow reload on snipers.
Secondary weapon: B23R I recommend this because is 3 round burst and its a quick kill and you switch to it fast so if you miss you can try to pull it out and get the kill.
Perk 1: Based on your opinion
Perk 2: fast hands or toughness.
I like fast hands because I feels faster so that you can switch your weapons really fast and pull out your secondary so if you miss you will get the kill.
Perk 3: Dexterity
Dexterity so when after your sprinting you can get the quickscope faster.
Tactical: Tactical insertion
I will explain while this is useful in a different topic.
Lethal: Your opinion
That's the sniper class setup that I really recommend and why.
