Sniping

All you have to do is know your enemy. When sniping you should always have the perks bling, stopping power, and ninja. With these you are invisible to enemy kill streaks and heartbeat sensor. for your sniper i would recommend the intervention or Barret .50 caliber. for your attachments i would recommended fmj and heartbeat sensor if your playing hardcore then put a silencer and heartbeat with bling, cold blooded, and ninja. Also try not to stay in one spot for a long time once your get about 2-3 kills move on slowly with your secondary out. for your secondary if its a small map i suggest a sniper for larger maps a semi or auto pistol will do fine.
