Hope someone can help me?
When I screw the 580cc bottle back on rifle when tuning it goes on easy until you feel some tension then air rushes out at a rate of knots! Continuing to tighten it does stop air flow, after plenty wasted air, this does not seem right as originally bottle screwed on and off with almost no wasted air and easier to seal quickly. Same mega air is wasted when removing bottle.
I am not sure if the Dowty seal\washer between bottle and rifle is the issue or if there is an O-ring inside the neck of the valve on bottle? I have heard there is an O-ring inside valve housing, apparently 9.3mm x 2.4mm NBR90. I am not sure I see an O-ring inside valve, although I do see a slightly darker portion of neck about 4-5mm below end of thread that screws bottle on, just above valve pin, I just cannot see clearly if it is an O-ring.
Can anyone confirm anything about above and maybe an accurate schematic or PHOTO photo of this internal O-ring in place? How does one get the O-ring out if it is indeed what I see???
Thanks and regards.
