You can acquire the legal 37/40mm smooth bore variants at any store which sells Tokyo Maru paintball Airsoft guns. They have a metal rail/receiver and either an aluminium or poly tube. Looks like the real thing, but is completely legal to own in Canada. If you try to import something else, make sure it is the "non destructive devise" variant.
