Petar Posted January 9, 2017 Share Posted January 9, 2017 Hello guys,I need help with decision about PSI for my Tokyo Marui M9 GBB.I'm buying new can of duster spray,but I'm not sure which PSI/Bar should i chose,because like you know,Tokyo Marui is made of plastic,so I'm worried that i will break it if i chose stronger.Until now i used duster,and i couldn't get slide to lock (i tried green gas and it works normal)and i think it's because it's too weak,but i can't be 100% sure because i couldn't find PSI on duster's can.Now I'm in dilemma should i use 5 Bar (72 PSI) or 6 Bar (87 PSI)?I'm always shoot indoors so temperature is 75-81 F.However summers are hot here in Croatia,so I'm worried that gun will break in hot days if i use 6 Bar.In summer temperatures are between 91-95 F.I want to prolong gun's life as much as i can,and i want to keep internals in best condition possible,so i won't use green gas so keep in mind of that.Every comment is welcome Link to comment Share on other sites More sharing options...
Supporters Monty Posted January 9, 2017 Supporters Share Posted January 9, 2017 Just use 144a gas, no need to over complicate things. Link to comment Share on other sites More sharing options...
Petar Posted January 9, 2017 Author Share Posted January 9, 2017 There is no 144a gas in Croatia,and shipping to my country is really expensive. That's why i only have access to computer compressed air-duster. Also,many if not all IT stores here have dusters without HFC. Green gas is also not an option because i want to prolong gun's life as much as i can. Link to comment Share on other sites More sharing options...
