I picked up the Sig Sauer MCX just to play with. I'm going to use a 13ci 3000psi bottle with the output regulated at 1100psi. I'm not familiar with the 88g Co2 but was wondering what output the psi is with the Co2 versus the 13ci 1100psi output on the HPA bottle? Will I gain FPS? Has anyone played with the Sig and tried to get the FPS up on them? Would be nice to shoot some heavy pellets in the 700fps range.
