Stouker, a manufacturer, is known for creating the main concussion chamber that the Sissks employed in the creation of their well-known firearm, the Stouker concussion rifle.
Despite this, information regarding the company itself and the original purpose of the Stouker concussion chamber remains scarce; however, the assertion that the Stouker concussion rifle was made entirely "from scratch" suggests that the concussion chamber might not have been initially designed for weaponization.
