This is for the G6R.
People have been posting about their ASA plungers falling out and ASA's not bleeding properly.
People have suggested soaking the o-rings in DOW 55, but myself and another timmy head both agree that it will only soften the o-rings and cause them to tear.
The stock o-ring on the plunger is a 004 70 Durometer O-Ring. We both think if the if an o-ring with a higher Durometer rating would probably fix the issue.
The issue is getting the o-ring on and off plunger.. as it is extremely small and can be a very daunting task.
Food for thought from both me and the mad scientist. (when I say WE BOTH think... I mean him and I agree, because majority of the time, the mad scientist is alot smarter than me)

WARNING: THIS WILL VOID THE WARRANTY OF THE KNOB
I chucked the knob up in my lathe and cut about .020" off of the inside of the one end. this allows the knob to unscrew just a little bit further and allows the air to bleed as it should. It will not matter what take you use or what. Bob Long just kept a tight tolerance where they didn't need to. having a little extra room does not hurt this part at all.
I am a very experienced machinist and would not recommend this to the average joe with a lathe. This can go wrong and you will be without a gun because you won't be able to turn your air on.
I also took a measurement for anyone looking to do this so they know how much i took off. .085" is what i cut it down to. you can clearly see where i cut so that there is no question of what to do. DO NOT CUT DOWN THE PLUNGER by cutting down on the plunger you will keep the tank from opening in the first place.
