[discussion] Possibility GBB M4 C-Mag build ?

[kullwarrior]

honestly if you can make a c-mag I would say GO HPA, screw the Propane, CO2 you would probably wanna use atleast 4 powerlet, and HPA is the best solution, if you could make a 100 rounder with HPA you basically earn the cure to cancer for the current GBBR

an HPA tank would be too big for use in a c-mag.
and with the pressure of HPA, it's not just a simple matter of making a reservoir and slapping everything together. these HPA tanks need to be tested and certified be for sale.. last thing we need are exploding mags.
i see CO2 as the best solution along with propane.
