This one goes out to the Weihrauch HW100 experts. (In particular: Bludlust, I'm counting on you here. Don't let me down! )
I'm making preparations to modify my FAC HW100. My shooting priorities have changed, and I want to build a 12 ft.lb carbine that I can use for HFT.
To this end, I've recently bought two Walther/Hammerli AR20 maxi air tubes. These tubes have a safe working pressure of 300 Bar (more than 400 Bar test pressure). One of them will be modified to accept the air outlet valve from my HW100's existing air tube.
What I need to know is this: what is the safe maximum input pressure that the HW100 action and regulator can accept?
It's obvious that just because the air tube I'll be using can tolerate 300 Bar, it doesn't necessarily mean the HW100 components can!
