A trigger position detection system in replica firearms which comprises a sensor built from at least one light source D1 (5), and at least one receiver Q1 (6) converting a light signal into an electrical signal. The light source D1 (5) and the light receiver Q1 (6) are located on a printed circuit board (7) in a way that they are deviated from the vertical axes running perpendicularly to the upper surface of the cylinder edge by an angle from the range of 0-90, and their active surfaces are directed towards the replica trigger (1). A method of detecting the position of the trigger in replica firearms comprising controlling the light source D1 (5) in such a manner that at fixed regular time intervals, each time it emits light for the same period of time, while directing the beam reflected from the surface of the replica trigger (1) towards the receiver Q1 (6).

A foregrip for a projectile launcher is disclosed. The foregrip includes a proximal longitudinal end mounted to a projectile launcher and a distal longitudinal end positioned away from a projectile launcher. An access panel is hinged to a battery compartment at the distal longitudinal end of the foregrip. A release button separates the access panel from the foregrip. The release button is located on the proximal longitudinal end of the foregrip.

A projectile launcher, comprising: an internal tank configured to receive a combustible gas through an inlet, a barrel, a projectile storage portion, a piston, a trigger assembly configured to operate a spool, and a flexible structure configured to wrap around the spool. The flexible structure may be connected to the piston, wherein pulling the trigger assembly causes the spool to rotate to cause the flexible structure to pull the piston forward. The piston may be configured to expand a combustion chamber behind the piston when pulled forward, wherein pulling the trigger assembly causes the combustible gas to enter the combustion chamber created by the piston moving forward. The combustion chamber is configured to collapse after the shot is executed due to a spring bias applied to the piston to a backward position and due to the flexible shaft being released from pulling the piston forward.

An empty-magazine power-off structure of electric toy gun includes a bore component and a power source switch; the bore component has a ball firing pipe and a ball feeding pipe connected to the ball firing pipe, a ball chamber is formed in the ball firing pipe, and the ball feeding pipe has a ball guiding channel communicated with the ball chamber from an external side; the power source switch is relatively disposed at an outer side of the ball feeding pipe, and at least has one trigger part protruded into the ball guiding channel. As such, when a bullet ball in the magazine passes the ball guiding channel, the bullet ball is able to press the power source switch to determine whether any bullet ball remains in the magazine.

The piston may be configured to expand a combustion chamber behind the piston when pulled forward, wherein pulling the trigger assembly causes the combustible gas to enter the combustion chamber created by the piston moving forward. Pulling the piston forward loads a projectile into the barrel from the projectile storage portion in response to pulling the trigger. Gas in the combustion chamber is ignited while the piston is pulled forward, and igniting the gas causes a pulse to travel through the piston for executing a shot by launching the projectile through the barrel. The combustion chamber is configured to collapse after the shot is executed due to a spring bias applied to the piston to a backward position and due to the flexible shaft being released from pulling the piston forward. Collapsing the combustion chamber causes hot gas generated from the shot to be released. The gas may be green gas.

A shooting controller of a paintball gun includes a mechanical shooting apparatus, an electric shooting apparatus, a pneumatic apparatus, and a switching apparatus. Operating the switching apparatus may switch the paintball gun between a mechanical shooting mode and an electric shooting mode. In the mechanical shooting mode, the mechanical shooting apparatus drives the pneumatic apparatus to shoot a paintball when a trigger is pulled. In the electric shooting mode, the electric shooting apparatus drives the pneumatic apparatus to shoot a paintball when a trigger is pulled.
