User blog comment:Evehorizon/Barret 50 CAL. vs WA2000.Who would win?/@comment-1079585-20100305050823

Depends on setup, unless you are talking about real life, in which case the M82 for really long ranges and anti-materiel purposes, WA2000 for human targets at medium and long range.

In game? WA2000 if you are using a silencer and/or Cold-Blooded, Barrett if you aren't using a silencer and are using Stopping Power.
