Do the spring model shoot as accurate as the vortex ram.its was really accurate.I don't know if I want to spend the money to buy a pump&probe just to see if it will work.but a PvP pistol looks good.
Hatsan has it's own fill probe that works for both their PCP's and gas rams but I've never seen one that's a foster fitted setup. When you are set up, should look like the pic below. Adapter I mentioned is already connected to the Hatsan probe.PCP's, yep, 2 of them. Hatsan Galatian III QE .25 and a Hatsan Flashpup also in .25.
