Derya MK-12 shotguns were recently prohibited as AR15 variants.Yes, it is aesthetically similar but it isn't a variant. It shares no parts and operates completely differently, not a clone. The SKS looks similar to an AK pattern rifle but is still legal still to own and purchase.
If thats not enough to convince you that A) this would undoubtably be deemed a prohibited SPAS variant and B) your understanding of the term variant is clearly not the RCMP's benchmark, then I wish you luck in managing your expectations.
