Buddy bottle change

[Tomislav]

Greetings!
I just purchased a new bottle for my Rapid MK2 FAC and was wondering what is the most efficient way to drain the air without having to discharge firing it until it is empty. TIA

Remove the Neck O-ring and screw the bottle back on until the air starts rushing out!!!

Good Luck,
Stuart

You can buy a special bottle draining tool from best fittings which is useful.
