are they the same thing

[lost2]

i know is a stupid question but here it goes:
hpa and N2 are they the same thing? can i use n2 on my pilot acs?

[marvin-martian]

yes they are the same thing, and its better if you use it in place of c02

yep ... HPA, compressed air, N2, nitro ... it's the same thing ... cleaner way of firing your gun ... (just givin marv some feedback ... )
