System 7 GBB and Green Gas
 

Hello All,
I was looking at some of the system 7 GBBs on sale at AirsoftGlobal,
Specifically the SP 2022 and the HK USP Compact.

I noticed that both of them specify 134a gas whereas the HK USP Match says green gas and 134a.

Does the SP2022 and USP Compact System 7s take green gas?

Can someone *with* a SP2022/USP Compact confirm?

Yes...my friend runs his KSC Sys7 USP C on propane....not broken yet...lol

Generally they are all ok with propane, the SMGs seems to be a bit sketchier with the different versions(ie the KSC Japan MP7), but they should all take propane with minimum to no mod....

Taiwan version guns will take propane no problem. Japan is a non-non.

Have a System7 SP2022, use it on propane. No problems, but the slide notch started warping (plastic slide). Not sure if that's related.

Hey Duff, is yours a Japan or Taiwan model?

How many rounds have you run through it?

get taiwan version it takes propane easily... sure japan can take propane, but the cylinder wont last that long unless you can find aftermarket parts (cylinder) made for your gun.

Just got a Taiwan Version KSC System 7 SP2022 and the thing is not only amazing to hold, it kicks like mule and fire like a dream, very little cool down....all on propane.

Trigger pull was very light and short. Metal slide is alot nicer than i thought it would be...

I thought System 7 was all hype, but after putting 10 mags through it....i know their solid piece's out of the box.
