"MW3 Brings Back Highly Anticipated Gun Feature"

Modern Warfare 3 is set to bring back the long-awaited weapon vaults feature, which allows players to level up weapons and attachments before unlocking their base. The new system will rely on cross-contamination of attachments between guns and will be introduced through After-Market Parts in the Gunsmith customization section. The specific details of the two weapon vaults have not been revealed yet, but they are expected to offer unique weapon configurations. Players will have to wait for the Modern Warfare 3 Beta to see how the feature will work.
