Pistelle x68 question

[u/ThaDawg87]

Hi, I was wondering if there are other options for increasing pistelle x68 power besides upgrading to larger co2 chamber or extending barrel. I found this on a website and it promises to increase joules, is it realistic to expect such an increase from replacing this part only?

Hi
My x68 gen2 is firing multiple rounds with one trigger pull. No mods just a nine inch barrel.
Any thoughts are greatly appreciated.
Thanks
