Hey guys,

I recently got a Japanese Marushin revolver and was wondering if there is an alternative to HFC-134A known as gun gas in Japan.

Some people have told me to just use regular Green-gas but I am worried about premature wear due to the higher pressure.

Although the Marui's are strengthened to some degree to use green gas other companies like Tanaka, Marushin, etc do not.

I used to be able to buy them from electronic supply stores as circuit board cooling gas but it seems the EPA has deemed it a green house gas and has banned it in 2015. I know the EPA is a American Agency but Canada follows EPA trends pretty closely.

Using normal computer duster is questionable, the added bitterant agent is sticky and likes to gum up valves over time so it's a no go for me.
