WE M4 / Scar / PDW and CO2 mags.

[Ajax]

Hi all

I am looking for some first hand comments from CO2 mags users with WE M4 platform.

I am especially interested in wear and tear (is it much worse than green gas?).

What about FPS? if my gbbr is set spot on with green gas how much I can expect CO2 to push it up?

Cheers
