Look as this crazy fella presents a Full Auto Battery Firing PVC Air Gun that shoots an insane 600 Rounds Per Minute (at least he says so). What’s more, the speed of the batteries is evaluated 200 feet per second. This is truly amazing and as you will see, the ‘scientist’ is excited with his perfect work of art. He resembles an evil genius when he begins laughing at the weapon’s effective shooting. He says the total cost of his ‘gun’ was only like 30 dollars.
