Hi again, tried your advice but the mags are still discharging. Started using WE nurpol black gas and am keeping Abby well maintenance gas in the mags but they're still discharging. Any further tips?
The mags vent after 3 or 4 shots (they get really cold really quickly if that helps). I'm filling them up with the bottles upside down as well, I'll have a look on YouTube as well.
does the top slide get stuck in a particular places like does it stay to the rear or does it get stuck just be fore it fully forward and does it do it every time in the same place or is it different position when venting
as sounds like some thing is not lubed properly or the hop up rubber has swollen and nozzle cant reset properly but that would be after shot on not 3/4
