Abstract: The present invention is generally related to paint ball firing devices. More specifically, the present invention is related to paintball land mines, which can fire multiple paintballs simultaneously and methods of making and using same. Furthermore, the present invention is capable of allowing the device to be disassembled (i.e., field serviceable) and provides a range of combustion chambers, barrel assemblies, and cartridges to be used in the device. In this manner, a wide range of projectile types and feet per second (f.p.s.) projectiles can be used in the device.

Abstract: The present invention is related to paintball land mines, which can fire multiple paintballs simultaneously. Also, the paintball land mine utilizes a firearm blank or nail gun cartridge for its propellant. Furthermore, the paintball land mine includes reed valves associated with the ejection of the paintballs so that after the initial blast of the propellant to eject each paintball, the reed valve associated with the ejected paintball is closed, thereby preventing the rapid escape of unused propellant. Finally, the paintball land mine can be either detonated by a trip wire or detonated electronically through the use a remote-control device.

Abstract: A paint ball grenade includes a base having a chamber for holding a compressed gas, an outer housing mounted on the base, the outer housing including guides through which fluid communication is provided between an interior and exterior of the outer housing, each guide releasably holding a paint ball, a valve arrangement for blocking fluid communication between the chamber and the interior of the housing in a first position and for permitting fluid communication between the chamber and the interior of the housing in a second position, an actuator for opening the valve arrangement to provide fluid communication between the chamber and the interior of the housing to eject the paint balls from the guides, and a reed valve separately associated with each guide for substantially preventing further supply of the compressed gas through each guide after the paint ball therein has been ejected.
