Apparatus for acquiring data for configuring a pneumatic air gun comprises a data storage device and a controller. The controller is configured to determine a required velocity for a firing and determine a pressure of an air reservoir, or a pressure in an air flow path at a position downstream of the air reservoir of the gun. The controller is configured to determine a value of a valve activating parameter for the firing and determine a measured velocity of a projectile fired from the gun using the determined value of the valve activating parameter. The controller is configured to determine whether a difference between the measured velocity and the required velocity is within a required limit. The controller is configured to store the determined pressure and the determined value of the valve activating parameter in the data storage device as mapping data for configuring a future firing of the gun when the difference between the measured velocity and the required velocity is within the required limit.

A hand grenade for launching BB bullets includes two half shells each including a spiral bullet storage and one half shell further including a discharge opening; a hollow, cylindrical base including a bottom recess, an air passage communicating with one bullet storage, and a valve at an end of the air passage; a steel ball on the recess to block the valve; a pressing assembly including a disc urging against the steel ball, a hollow cylinder extending upward from the disc, a magnet in the hollow cylinder, and a rod partially in the hollow cylinder to engage with the magnet; a hollow, cylindrical member threadedly secured to the cylindrical base; a cup-shaped cap threadedly secured to the cylindrical member and including two opposite projections on an inner surface and a bottom through hole with the rod passing through; and a switch including two opposite protrusions under the projections respectively.

A projectile component that can be removably attached to a flying vehicle is disclosed. The projectile component includes a net configured in the projectile component, a receiving cavity configured in the projectile component, and a weight attached to the net via a string. The weight can be configured in the receiving cavity in preparation for firing the net from the projectile component. In order to entangle a target flying vehicle in the net, a cocklebur associated with the weight is included. Upon firing the net from the projectile component, and upon the net engaging with a target device, the cocklebur becomes entangled with the net to secure the target flying vehicle. A drawstring structure associated with the net can also be used to ensure that the net envelops and captures the target flying vehicle.
