Our MEGA PRO BIG ASS PROMO T-SHIRT LAUNCHER is one of the best launchers in the country for shooting the longest distances. This unit reaches distances of 20-over 400ft. You decide the distance you would like to shoot the t shirts by gauging the pressure you build up which is done by pressing the lever till your desired pressure. The more pressure the farther the distance. This unit comes out of the box with its very own bag for toting around, spare parts, oil for the gun, a 20 ounce Co2 tank and a PDF file we send you online with full instructions on how to care and use our t shirt launcher.
