Pneumatic riot-proof pepper ball launcher is a kind of launcher powered by compressed gas or carbon dioxide, which adopts a smooth-bore gun tube. Its structure is similar to that of an air gun. There are precedents in the United States, Britain and other countries, such as changing the existing paintball gun into a police riot launcher, and specially developing and dyeing bombs, pepper balls and rubber bombs. (At present, pneumatic riot-proof pepper ball guns are supplied by traditional paintball guns, magazines like rifles or rotatable magazines, etc.)

18.4mm pneumatic explosion-proof pepper ball launcher uses compressed liquid as driving energy, and there is a rotatable magazine above the barrel for ammunition, and the pepper ball projectile is driven by a driving spring for ammunition. Compared with the pneumatic riot gun with funnel-shaped magazine (the riot bomb falls into the launch tube by its own mass), the gun has a large bomb capacity, and there is no need to worry about the magazine tilting or inversion when using it. The pneumatic riot pepper ball launcher is characterized by no initiating explosive device, convenient management and safe use. The muzzle kinetic energy of the projectile is low, which is not easy to cause fatal damage to the target and has good safety; It can fire 18.4mm series fragile ammunition in single shot or multiple shots. It is mainly used to subdue criminal suspects who are recalcitrant and carry weapons within 20 meters, and to disperse small and medium-sized riot groups who illegally assemble, March and fight within 50 meters.
