We have seen a variety of odd ball conceptions ranging from potato cannons to Matrix mobile phones. So, now it is time for some conventional fun with an old school paintball gun. Except for in this instance, the paintball gun is wholly home made by Instructable user Geckowil. According to the creator, the contraption is made from cheap Steyr AUG AEG (used for light weight rifles in the airsoft category), while the design part (other than the barrel and breech) has been specially customized to his preference. The whole system takes around 4 seconds to fire, starting with the activation of the attached air compressor to the pulling of the trigger. As for user convenience, we can only hope for a safe solution to all those wires hanging dangerously.
