ac12, if you are inverting a CO2 supply tank that has a dip tube (intended to supply liquid CO2) then by turning it upside down you are only getting gaseous CO2.... Most large CO2 tanks have a dip tube, but not all....If you are wondering how much CO2 by weigh to put into a gun, the ratio is 7/18 oz. per cubic inch (note that is stated on the top of that coloured chart I posted above)…. There are 16.4 cc per CI, and 28.35 grams per oz. so that works out to (7/18 x 28.35) = 11 grams per CI, or (11 / 16.4) = 0.67 g/cc.... Therefore if your gun has a reservoir of 100 cc (6.1 CI) you can put 67 g (2.4 oz.) of CO2 into it....Bob
Thanks Bob, that will help. 28g per oz... 14g per half and 7 grams per 1/4 oz... Dang that rings a bell from the old days. HAHH!SuperChicken.... I also own one of these Ninja fill stations for HPA with a relief I'll post a pic tomorrow, Mine is a homemade version but my bleeder is at the other end. What I found it that bleeding at the gun end allowed meto fill the line with liquid CO2.But it is set up for the ball valve seat of my Ninja HPA regs, the CO2 tank has a Pin and this fill station opens it before completely seated. Your link may be just the ticket for my CO2 set-up that is like this...And yes, we would either be done with this or missing some important parts.

Ray, a gun that holds two 12 gr. CO2 carts, like a QB78, should have a volume of about 45 cc with the carts removed.... You would have to measure the ID and the inside length to be sure, then calculate the volume....V = ID x ID x Len x PI/4A 45 cc tube would hold about 30 grams of CO2 (just over 1 oz.)….Bob
Which one Ray?
