For further clarification on the point of concern, of course, the definition that Mr. Motz may be looking for is in amendment G-4, proposed subclause 1(1.3). It talks about what a firearm part specifically means. It means:
“firearm part” means a barrel for a firearm, a slide for a handgun and any other prescribed part, but does not include...a barrel for a firearm or a slide for a handgun if that barrel or slide is designed exclusively for use on a firearm that is deemed under subsection 84(3) not to be a firearm;
It's a very specific definition. It's there for folks to look at.
