Hello!
I’ve just bought the HK417D GBBR VFC (1J version), and i would like to know if there is a way to increase the joules power. I thought that maybe setting up the NPAS could allow me to do that. Or maybe i can change the gas valve, IDK…
Has anyone an idea?
And do you know what are the different pieces between this 1J version and the 1.3J version that makes the power change?
Thank you for your answers
