Improvements in a projectile launcher is disclosed. The launcher converts an airsoft gun to fire paintballs to handle feeding either airsoft projectiles or paintball projectiles depending upon the installed kit. The launcher includes a hydraulic damper allows the fire and reload to operate in a controlled motion that allows a projectile to be fires and the next projectile to the loaded in a rapid succession. An improved magazine allows multiple different types of projectiles to be installed in the magazine. An interchangeable trigger mechanism and interchangeable barrel to launch different diameters of projectiles. Different types of firing mechanisms can be removed and interchanged in the launcher. In addition to the barrel can also be changes as the projectile is changed.

An insecticidal gun including a gun body, a feeding member, a percussion member, a trigger, and an electric drive mechanism. The gun body includes a launching chamber; the feeding member is slidably connected to the gun body and includes a material storage chamber configured to communicate with the launching chamber. The electric drive mechanism is configured to drive the percussion member to move in the launching chamber. When the percussion member is driven by the electric drive mechanism to move, the feeding member moves along the axial direction of the gun body, so that the material storage chamber communicates with the launching chamber intermittently. The trigger is rotatable with respect to the gun body to activate or inactivate the electric drive mechanism.

A hand-held gun for interchangeably propel a round of one of solid and liquid consistency is provided. The gun includes a gas actuator, a firing module, a magazine, a loader and a barrel. The gas actuator stores and releases compressed gas. The firing module includes a chamber for receiving the gas to push forward a bolt in response to actuation by a trigger. The module is disposed forward of the actuator. The magazine contains ammunition that constitutes the round. The loader laterally receives the round from the magazine and longitudinally receiving the bolt to eject the round. The loader is disposed forward of the module. The barrel directs the round ejected from the loader, and is disposed forward of the loader.
