With all due respect, you are confused. Regardless of what you think about their quality, these are functional firearms, not "non-guns."
Canada must have some law regarding shipping a functioning firearm, hence the separate lock shipments. If these were "non-guns" the wouldn't have to jump through such hoops, now would they..?
this is simply a case of shipping the firearm in pieces to dodge shipping regulations or something, that is one thing.
But if this is a case of shipping the firearm in pieces so as to disclaim responsibility of selling a functional firearm, that is something else entirely.
Given the history of "drill it yourself" touch holes, I'm skeptical.
