Thank you for the question.
The regime that's being proposed here is with regard to acquisition and import of firearm parts. Mere possession of a firearm part, i.e., a barrel or a handgun slide, is not going to be criminalized.
What this set of amendments would do is that when there are particular offences, and in this case a peace bond, it says that somebody may not in that case possess a firearm part, in amongst all of the other firearms or other items that they will not be allowed to possess.
