It depends.

If you are using a silencer and Stopping Power, the WA2000.

If you are NOT using a silencer and NOT using Stopping Power (Cold-Blooded is the only other good sniping perk), the WA2000.

If you are NOT using a silencer and using Stopping Power, it's between the Barrett and the M21. The Barrett gets one shot kills to the stomach while the M21 has less recoil and reloads faster. Technically the M21 is much better, but MUCH harder to use.

If you are using a silencer and NOT using Stopping Power, the M21, since such a setup will always need two shots to kill.

For your secondary, definitely use the PP2000, and put Extended Mags on if you have them. Otherwise just use any attachment except for Akimbo or FMJ, since those both suck.

For Perks, use Scavenger (you basically need it for the nuke), Stopping Power or Cold-Blooded, and Steady Aim Pro. For equipment, use Claymores for camping or Semtex for moving. For special, use Stun.
