Anarchy 37mm Launcher Details

Introducing The Anarchy, a small 37mm launcher that is highly efficient and affordable.

The Anarchy was developed with 3 versions, the Hand Cannon, the Under barrel and the Double Door Knocker.

The design was originally created by Danny Meatball and was later developed by Atticus, who extended the frame and implemented the “flip to side” design.

The project was then handed over to the current owner, Unseenkiller, who oversaw its completion with the help of a few others at AWCY and in the 3D Gun community.
