Swiss Arms Protector Help finding mag seal

[Moe]

After fighting to understand why the CO2 would only last half a mag. I discovered the rubber seal that is on the top of the mag for transferring co2 to the bolt is torn. The mags are $50. The guns are $100. Would rather just buy the seal if anyone can point me to who has them. Any help appreciated.

If you can`t find what you need on any of the airgun forums ,try taking the old seal to a place that sells seal for industrial pneumatic equipment ,I`ve had good luck doing that for some of my Co2 guns ,also try paint ball repair places .Hope this helps
