Two homebuilt pistols were seized among other firearms on Tuesday by police in Sydney. They appear to be of a closed bolt design, using a plastic lower receiver with an angular magazine well. Both examples appear very well made.
Look at this thing
That’s not a mass produced pistol, that’s something some bikers in the Land Down Under made in a garage. It’s not difficult & with the 3D printing tech becoming common place, these designs will not only become more common, they’ll also be more rugged. And still disposable & untraceable.
This is why laws that only affect the law abiding are useless.
