This is a 24" Chrome-Moly tube with a rich bluing designed to convert your Co2 QB78 to High Pressure Air (HPA) operation.

Kit comes with 24" tube, foster Quick Disconnect adapter and cap. To install, your existing QB barrel band needs to be clearanced somewhat as the custom tube is slightly larger in diameter than the stock Co2 tube.

Please note: This tube is able to hold 3000psi, but a non-modifed QB is limited to 1600psi as the valve will lock-up at higher pressures.
