you see my main project now is to build a QEV cannon, I've already ordered a QEV but I have to wait to January becasue shipping is delayed or something like that.
Since a QEV gun needs a pilot valve I wouldn't have to disconect the gun from the compressor at all and I could use a pilot valve to reduce the pressure in the hose before disconnecting... so I'll just wait for my QEV to be delivered and then this wouldn't be a problem anymore.
BtB yes it works both ways either a small chamber or very long barrel... I am considering using a 1/2" 100 - 120 cm barrel and 50 cm chamber..... since I am using threaded pipes and fittings I could even make several chambers with different lenghts... like 25 cm chamber for silenced version and 60 cm chamber for more power and change them according to my needs or mood...
Right now it has very short hose about 60 cm long... I've ordered 10 m of airhose with a qev so that I wouldn't hve to disonect it when shooting
I don't think it is practical to mount it to a gun it weights about 7kg
