Hi all as the title says I have a TM G17 and it's playing up, I started to upgrade parts. First I bought a metal slide, up rated spring and the airsoft surgeon loading nozzle. At this point the gun was ok.
I then bought nineball mag gas router and a pdi piston it was at this point I started to have a problem. When i shoot, the BBs would just fall out the end so I took the slide apart again and made sure everything was back ok, still no joy other than discovering that the piston was the wrong way round! But with everything back together and a new nineball bucking rubber I'm still scratching my head wondering what the hell is it?
Any help will be much appreciated.
