Why was the 90 gram tank invented? Is it the same size as the tank that holds 88 grams, only having more CO2 forced in, or is there some other marketing reason? I would think that the extra 2 grams of gas wouldn't make or break sales?
Can this tank be removed from the gun and put back in later like those small camp stove propane tanks.
No, it has no check valve. It will just vent out.
what is the differnts between 88gram and 90 gram 2gram differnts hurt some guns?
No, it will work fine.
how many for $8.95
Can we leave the CO2 tank in the beretta cx4 for say, one month?
No, you will destroy the rubber seals. Plan on shooting it empty after charging the rifle.
