It's a seriously easy fix, if you have a dremel, some good glue, and a pen or some tubing.
And the M3 is a good enough gun that it's worth fixing.
If you can get yours open, there might be demand if you were willing to junk yours out depending on what's broken in it too. If your Cylinder isn't broken and it's something else that is, I'd already call that, and I think there's at least one other peroson on here looking for other parts.
