GBBR CO2 Magazines- need help
Okay so I have a WE PDW running on their original AWSS system and I had propane mags before but switched to their CO2s because it is cold where I live. I thought things would be all fine and dandy but they aren't. I can maybe get 12 to 13 rounds through a single capsule and that is on a good day when I give it plenty of cool down time (several minutes). My gun is also very well oiled and so are the mag seals. Sometimes my gun puts out just enough gas to get a very sad and slow bolt cycle. Any thoughts or reccomendations? Thanks guys.
Also do CO2 mags even have cool down time?
