A paintball barrel is the first upgrade most people make for a paintball gun. At RTS, we offer some of the highest quality barrels from manufactures such as Tippmann, Hammerhead, GOG Paintball, JJ Performance and Lapco. This includes a wide selection of rifled paintball barrels, micro-polished barrels, paintball barrel kits as well as paintball barrels of varying bores. Aftermarket barrels are labeled in conjunction with a thread pattern specific for a particular paintball gun. Simply select the barrel that is labeled to work with your paintball marker.
