Vulcan skins are recognizable for their unique paint job which was inspired by a sports design. Currently, the only member of this family is AK-47 | Vulcan which was added to the game in 2014 as a part of the Hunt Begins Update. The skin is also a part of The Huntsman Collection and can be obtained by opening the Huntsman Weapon Case. The AK-47 Vulcan is available in all five exteriors and can have the StatTrak technology attached to it.
