  • Austin from USA asked:

    I know the forearm would have to be removed for it to fit but would this work on the fusion 2?

    • Techstar from USA asked:

      Will this increase the fpe? How many shots do you get per fill?

      • Kelan from USA answered:

        It will not just make it HPA instead of Co2.

      • Techstar from USA answered:

        I found my own answer, but figured I'd post to help anyone else out: To get the full benefit of the HPA adapter, the hammer spring will need to be changed out. To do this, the stock will need to be removed from the AirJavelin. The two screws located on the rear of the receiver need to be removed in order to remove the stock. With the stock removed, two springs will be seen. Pull out the bottom-most spring and replace it with the spring that comes in the AirJavelin HPA adapter. Re-install the stock with the original hardware and the conversion is complete. The adapter is rated for 1100 psi- a pressure safely within the range of the AirJavelin's capabilities. This figure is 30% greater than the pressure possible by CO2–and there is also the advantage of a very consistent velocity for about the same number of shots that can be taken with a single 88-gram cartridge. At this higher regulated pressure, the arrows will launch at a higher velocity than the CO2-powered version, around 320 fps.
