Freak boring seems to be a recently popularized modification. I think having a factory option for a barrel that is Freak bored would be a big seller. You could offer that and sell a SP insert to make the gun usable and keep you legal (actually, does that even matter?) and let the buyer pick up other inserts if they want or need.
