So, does anyone know what the safe max operating pressure would be for a CX4 converted to HPA?
As CO2 can reach more than 1500psi at higher temps, I was considering 1200psi as a safe cut off point.
A little concerned about the semi auto function becoming over powered.
I plan on modding mine somewhat as soon as I can find a longer 15mm diameter barrel to machine to fit.
On that note, would anyone know where I can get a barrel, 15mm OD, 20 to 21 inches long in .177?

Thanks in advance,

Grunt

You only posted yesterday. Lots of people here using QB parts; give it a few days, or or it may even a repost in seven days. :)

So I found a barrel and now just need to find my chrony and fix my lathe. :)
Still hoping for some ideas about max HPA pressure to run? Anyone :?:
Thanks in advance.

I wouldn't push it more than C02 on a hot day. MAX 1500, and I only feel safe running it around 1200. Higher PSI might play havoc on the semi auto system.
