The gun kinda looks like a gun from fallout, it works pretty good and shoots 6mm steel bbs at 700 fps!

Du très beau travail réalisé avec des matériaux "over the counter" et sans outils spécialisés, very good job!

I bet you could up the pressure even more but even as it is you're getting very respectable power and shot count.

Thanks yall ,to lncrease power I can either increase the volume between the preset and the valve or increase the pressure (for instance 9mm pcp rifle that shoots 200joules uses ~20ml at ~120 bars, mine is ~5ml at 60 bars), but both increase will lead to lower shot count and higher firing pressure. I should try in the future making a more solid build with a bigger air tank and maybe a balanced valve to make big bore pcp. I should also find a way to modify preset to delivers hundreds of bars since paintball tanks are cheap.

You can get a bit more pressure by adding more shims to the regulator main spring to increase the precompression:
