2nd does not have a sporting clause however the gce68 does i believe.
The sporting clause in the GCA only applies to imports AFAIK. There is another 'sporting purposes' clause in the Destructive Device definition though that allows for an exception for shotguns. That was the one used to rule that the USAS-12, Striker 12, and Streetsweeper shotguns as destructive devices.
Regardless, neither one really applies to this particular situation.
