notice he said the mag already has a reg,so he wouldnt, but as i said you can never have to many regs!Originally posted by ericostani
you need the reg on the bottle for any gun, to bring the pressure down to an operating pressure - for a mag about 800 psi which is the same pressure as co2, that complete comes with one already i think, which brings it down from 3000psi to co2 pressure 800psi
Your mag can only cope with 800psi
