- For Cybergun Double Eagle FN 509®
- 20-round capacity
- Licensed FN Herstal baseplate
If you need spare mags for your Cybergun Double Eagle FN 509®, this will do it! The Cybergun 20rnd Green Gas Magazine is constructed from alloy, with a steel feed spring, polymer feed lips, and an FN Herstal-licensed baseplate. This mag is designed specifically for Cybergun Double Eagle FN 509®; compatibility with other brands is unlikely.
The magazine is loaded through the feed lips at the top. You can either load by hand or use a speedloader, depending on how quickly you need to get back online. To fill the magazine with green gas, use the fill valve located at the bottom, recessed into the magazine baseplate. Invert the magazine and your gas can, hold the two together for 5-10 seconds, and you're filled up and ready to go!

Special Instructions
Always keep a small amount of gas in your magazines to ensure the seals remain inflated. This prevents leaking magazines. Your magazines do not need to be full of Gas to keep them healthy. We also recommend the use of Abbey Predator Maintenance Gas 270ml whilst your magazines are being stored to keep them in top condition.
