Hi Guys, first time poster, and was wondering what is the rated psi or bar ? What’s the max pressure anyone has used and how do you find it?

Thanx for that, I wasnt 100% sure how to read that graph.
Good man !
Good man - this is me! :) The more interesting question is - how many strokes of the mares manual pump is required to reach this pressure (if you are not using some sort of an inflator) ! This information should be provided in the manual. Also 13 bars is probably a recommended pressure - I suggest pumping it and checking periodically if you can handle loading the gun. My Cyrano 850 for example requires 500-550 strokes. Above that loading is difficult and recoil messes up accuracy. I think yours can handle 250 strokes or so.
