A 20-year-old neo-Nazi who attempted to make his own gun using a 3D printer and downloaded terror materials online was jailed for six-and-a-half years on Monday.
Jack Robinson, of Hawthorne Crescent, Portsmouth, was at an advanced stage of building the semi-automatic when police raided his home, where they found 1,253 ammunition and nail gun cartridges.
A weapons expert told Winchester Crown Court that the nearly-assembled gun would have worked as a lethal weapon.
The court heard how Robinson began expressing antisemitic views from the age of 17, frequently referencing Hitler and Mein Kampf under usernames such as “Kill all Jews” on the platform Discord.
Alongside the gun parts, police found a haul of Nazi memorabilia, knives, stab vests and manuals on how to make bombs.
The Holocaust denier had also written a note expounding his far-right world view of white supremacism and antisemitic conspiracy theories, and had searched for extreme-right content online more than 3,000 times.
Among the tranche of extreme material were ‘execution’ videos showing young men being killed under a swastika flag.
At a separate hearing Robinson also admitted two counts of making indecent images of children and two charges of possessing indecent images of children.
More than 700 images and videos were discovered on Robinson’s electronic devices, most of them material featuring children between six and ten years old.
One featured a child as young as three, while the other abuse images were cartoon or computer generated.
Most of the material was classified as Category C, but some were the most serious Category A.
Frank Ferguson, a specialist counter-terror prosecutor at the CPS, said: “Jack Robinson held extreme views and intended to act on them using the lethal weapon he was creating.
“Robison had over 1,000 gun cartridges and had instructions on how to make explosives which is a clear indication of the devastation he could have caused.
“He had called for death online and held extreme Nazi and racist views.
“Today’s sentencing shows the seriousness of his crimes and helps protect the public by removing him from the streets.”
