We’ve combined an exceptionally light-weight tank with the industry’s most innovative FS Hero regulator. The First Strike™ Hero Air Systems provides a perfect compact profile and adjustability that will let you stay in the game longer. Our new lightweight tanks are 30% lighter than the standard version of the same size and have the ability to adjust the position of the fill-nipple and gauge with groundbreaking magnet technology – no tools required. Measuring just at .75” from tank to ASA, the FS hero regulator provide a consistent, rebuildable, and reliable air source for any paintball marker. The FS Hero Air Systems all carry a UN ISO certification, one of the highest standards in bottles. Gone are the days of throwing out a tank after 15 year like with most carbon fiber tanks, these bottles will last a virtual lifetime.
