I think I even corrected you early on, when you stated that the gas was a function of temperature - and I corrected that, and stated that these guns operate on gas PRESSURE.
GAS TEMPERATURE doesn't have a fucking thing at all to do with how these guns operate, as far as the cyclic operation.
Now, go on here, and fuk with me, and tell me about Alaska, and Iraq, and -50, and +130. I dare you. That doesn't have ANYTHING to do with the beloved "gas temperature" gnome that you're trying to figure out here. Which is a non-event.
