I have a question, what is a decent low temperature to use a TM, with the green gas mod, and be able to shoot one full mag of BBs properly, in semi auto mode ? Let's say with green gas/propane (I bought ProTech green gas, any experience with it ? Is it propane lvl or below/above ? ). Would 0-5 degrees (Celsius) be ok ? With let's say mags kept on the chest side of a plate carrier, so hopefully "stealing" some body heat.
And I have a crazy idea that pokes at my brain for a while. Does anybody know if somebody tried a CO2 mod for the TM ? Couldn't find anything with google search ... but I was thinking, how about taking a WE/GHK/others CO2 M4 mag, that has the same or a very close shaped outer shell with the TM one and maybe 3D print the inner top part (nylon or similarly strong plastic), so it still fits the original mag systems/shell but now has the upper part of the TM (gas outtake and BB loader lip). It would be necessary to check somehow the output of the valve on a trigger pull to see if it doesn't release too much pressure for the TM to handle and maybe replace it with a valve that has a lower output, if such a valve even exists but ... yeah, what do you guys think about this idea ?
P.S.: still waiting for the gun to arrive, hopefully next week....
Later edit: I found this chart for nuprol:
Comparing Nuprol 2.0 with this chart https://www.engineeringtoolbox.com/propane-butane-mix-d_1043.html
it seems that it behaves like pure propane.
