G18C Extended mag feeder is broken.

[strigoi]

Hello All

As you can see from the video the magazine is a bit battered.

1st issue is it is leaking gas from the bottom constantly, a faint hissing noise.
Been informed i should put some silicone lube on it.

The second a bit more annoying is the feeder is broken and cant seem to find anywhere i could purchase one from as i have tried to superglue it but it breaks after a use or two. Can someone please advise on where i could buy the part for this.

Thanks!
