Call of Duty Black Ops 4 Weapon Concept The Tempest

Concept I did for the weapon of the specialist Prophet, design wanted an "automatic bolt action" dart gun, so I came up with the "super delayed gas system" (totally made up, I'm sure it won't work in real life), it has long and regulated gas system that will push the bolt back almost a second after each shot, so it feels like a bolt action but you don't have to manually operate the bolt.

Ethan Hiley did the initial 3d block in, I remodeled it and did the paint-over.
