wigeon jim Posted Monday at 18:18 Report Share Posted Monday at 18:18 Hi , my friend has a SMK M77 and it has a problem as he can’t get air into it, when he puts the probe in and opens the air tank he hears a click from the gun and no air transfer, anyone any idea what the problem might be, cheers Quote Link to comment Share on other sites More sharing options...

sportsbob Posted yesterday at 10:40 Report Share Posted yesterday at 10:40 (edited) It sounds to me his fill cylinder is low on pressure. If his air cylinder is virtually at the same pressure as the gun it is not possible to fill it , the gauge on the supply will closely match the gauge on the rifle. The click will be the fill valve opening inside the gun but if the pressure is similar to the fill tank it will close again.

bruno22rf Posted yesterday at 11:57 Report Share Posted yesterday at 11:57 Need to see a pic of the gun, the gun's pressure gauge and the tank gauge. Quote Link to comment Share on other sites More sharing options...
