Similarly to an answer to an earlier question, there would be an inconsistency in the Criminal Code with respect to the forms and other provisions.
Five or six provisions in the Criminal Code would say “firearm part”, and this would not.
It's a flag to people using the form or individuals using the form to use this as a model, and it would be an inconsistency between the provision and the form itself. This amends a form, not the actual provision in the Criminal Code, so it's reflective of that section in the code.
