Turns out WGC does not have replacement Cylinders, but Paintball-X has a new version out of their patented replacement cylinders, Version 2!
Looking at it, I'm not entirely sure how that's supposed to go into my shotgun without a lot of cutting, but if anyone wants to try a group order again, I'd be in...
MadMax, there's your pics you wanted, and this time it doesn't look like a replacement version in metal (at all).
[EDIT: Not that any of that info matters any more, I contacted them asking about shipping policies to Canada, and just got a reply that they no longer ship to Canada due to issues they've had with Customs. :smack: [END EDIT]
