Operator7 has a new review posted at Airsoft Community Europe... "To me it’s great to be able to have both Green Gas and CO2 mags working on the same gun. The way I using them right now is I’ll go through the CO2 mag first since it’s the one with more fun and power, and once this is depleted I’ll just load up the Green Gas one which will lubricate the gun and still give me a few more shots whenever I need it! To be able to have a second mag is great and most WE guns come out of the box with two mags. But if you’re looking for a third or fourth mag, then you should consider CO2 mags, since the gain in FPS, kick and sound is just what any Airsofter wants for a gun upgrade."
