SCAR-20 | Storm is a Consumer Grade-tier rifle finish, part of The Cobblestone Collection and dropped from the ESL One Cologne 2014 Cobblestone Souvenir Package.

A Souvenir version is available, dropped exclusively from cases collected during Major Championship matches and stamped with that tournament's stickers.
