Leaking CO2 Mag

[Kesslan]

Hey guys.

I've got a leaking CO2 magazine for my crappy Wingun WSGC-101 style CO2 NBB pistol I picked up off another seller on here recently. I mean hey it was cheap and does what I need to eh?

Specifically the leak is around the firing pin on the mag, and it's a fairly steady leak so gaming with it is definately a no go. Given the severity of the leak I'm assuming I some how need to get the brass piece that the pin is sitting in out to replace the seal or something.

Anyone here familar with these things able to hopefully give me some relatively good news other than 'buy a new mag' since the rest of it is perfectly fine and if it can be repaired I'd rather simply do that. Especially as I'm not sure where I can even go to buy spare mags for this thing.

Any help would be appreciated.
