A compact improved bug killing gun includes a compressed gas source fluidly connected to a chamber connected to a barrel. A compressed gas release mechanism is connected to the compressed gas source. A projectile storage magazine stores particulate projectiles and is located adjacent the chamber. A projectile loading mechanism moves the projectiles into the chamber from the magazine. A cocking mechanism is mechanically connected to the compressed gas source, the compressed gas release mechanism, and the projectile loading mechanism. When the gun is cocked, the projectile loading mechanism loads a quantity of the particulate projectiles into the chamber. When the compressed gas release mechanism is activated the projectiles are ejected from the chamber into the barrel and expelled from the gun. The gun optionally includes a laser sighting mechanism. The battery operated laser sighting mechanism is removably attached to the barrel or permanently attached with an integral, trigger operated switch.

A pneumatic air gun including a gun support, a barrel disposed on the gun support, a valve body, a pressure gauge, an air compression assembly, an energy storage assembly, and a triggering assembly. The air compression assembly is connected to the energy storage assembly, and the energy storage assembly is connected to the valve body. The triggering assembly includes a trigger support fixed to the gun support and a pull-bolt assembly, a trigger, a trigger button, and a hammer disposed on the trigger support. A spring is attached to the hammer. The trigger is connected to the trigger button. A loading thimble in the pull-bolt assembly slides on the gun support. The loading thimble is movably connected to the hammer and is adapted to control the hammer to reset and to be clamped on the trigger button.

A variable safety output control system for a pneumatic toy dart projector (toy dart gun) has an adjustable output power (pressure) control system for power adjustment. A variable safety output control system has a manual dual-sided pressure adjustment safety mechanism that controllably limits a pneumatic pump power stroke and the resulting pneumatic pressure for dart release. A guiding and release mechanism for the adjustment safety mechanism operates with spaced-apart pressure-portions and high-pressure requirements allowing an adult-strength-level adjustment while minimizing juvenile-strength-level adjustment for improved safety.

An airgun pressure system as described herein includes a pressure chamber comprising a cylinder extending along a length of an axis of the airgun parallel with an axis of a barrel of the airgun. The airgun also includes a piston disposed within the pressure chamber and translatable along a length of the cylinder to pressurize gas in the pressure chamber in response to an increase in force applied to the piston. The airgun also includes a rotating drum connected to a frame of the airgun, a cable operably connected to the piston and the rotating drum, and a crank handle operably connected to the rotating drum and configured to cause rotation of the rotating drum to increase tension on the cable and force on the piston to compress the gas in the pressure chamber.
