[others] 匣內氣有幾多Volume？

以Glock短匣為例，最多可以入幾多Volume嘅氣？匣嘅Gas capicity又係幾多？唔該兄

this is complicated and interesting question.

first to know is the size of the magazine's gas tank...
V = Width X Lenght X Height

then, what kind of gas you use?
Green Gas (1000ml) is somewhere around 140-170 PSI
134a is around 80-100 PSI

and please note the figures is based on atmospheric pressure at sea level, and varies depending on Temperature.

and then you can connect the dots
