GHK M4 CO2 Magazine (Version 2)

Want to use CO2 in your GHK rifle instead of green gas. CO2 produces a stronger kick and is more readily available everywhere in the world, so this magazine gives you greater convenience in finding cartridges. From our own internal tests, this CO2 magazine delivers a bit stronger recoil as compared with the standard green gas magazine that comes with most GHK rifles. The cool-down effect is also not as apparent and this CO2 magazine is a better option when playing in cold weather. Having both green gas and CO2 magazines for your GHK unlocks greater flexibility: Green gas for summer and CO2 for winter!
