This is the Horney Elephant!This paintball cannon cries out like a bull in heat and is fairly accurate.All the hardware is hidden by the camo mesh hood.The heart is a 12volt sprinkler solonoid run by 3 9volt batteries activated by a toggle switch.All Grumpy has to do is pump the air chamber to 100psi load with around 30 balls in a special wadding and flip the switch.
