The Stouker concussion rifle was a ranged weapon built from scratch by the vicious Sissk, who used it as their primary weapon. Stouker produced the rifle's main concussion chamber. The Stouker rifle was a weapon that fired a concussive blast at a range of up to thirty meters, creating an explosion about four meters in diameter. It also possessed a secondary firing mode, the blast from which was less devastating in terms of radius, but had a greater impact on the target.
