A man from Portsmouth has been sentenced to nine years and six months in prison for terrorism offences and attempting to manufacture his own firearm using a 3D printer.

Jack Robinson, aged 20, of Hawthorn Crescent, Portsmouth, was sentenced on 14 October 2024 at Winchester Crown Court. The sentence includes six and a half years in prison, with the remaining three years on licence.

Robinson pleaded guilty to multiple charges in May 2024, including:

  • Being in possession of a component part of a prohibited weapon, specifically the lower receiver for an FGC-9 MKII semi-automatic firearm.
  • Attempting to manufacture an FGC-9 MKII semi-automatic firearm.
  • Three counts of being in possession of a document or record containing information likely to be useful to someone committing or preparing an act of terrorism.
  • Additional charges related to possession of indecent images of children.

Robinson’s activities were uncovered as part of an investigation by the South East Regional Organised Crime Unit (SEROCU), which led to his initial arrest in February 2023. At his home, officers found a 3D-printed firearm, parts of a semi-automatic weapon, and ammunition.

Additionally, investigators discovered Nazi memorabilia, a handwritten note criticising Jewish people, and two digital copies of the Anarchist Cookbook. Counter Terrorism Policing South East (CTPSE) subsequently took over the investigation due to the severity of the case.

Detective Chief Superintendent Olly Wright, head of CTPSE, expressed concern over Robinson’s possession of extreme right-wing materials and the fact that he used a 3D printer to create parts for a viable firearm. “Robinson is a dangerous man who had used a 3D printer to produce the parts to make a viable firearm. Of particular concern was the fact he was motivated by a terrorist ideology,” Wright said.

The investigation resulted from close collaboration between SEROCU and CTPSE. Detective Chief Superintendent Steve Boniface, head of SEROCU, emphasised the effectiveness of this joint effort. “This case is a really good example of collaboration between SEROCU and CTPSE, and I’m really pleased to see that it has resulted in the conviction and sentencing of a dangerous man,” Boniface noted.

Arrest some nutter and ignore millions of hostile ropers: politicians are cowards of the first order. One day that cowardice will reap a terrible harvest.

It is good they got him before he was able to kill someone. I would have liked to see a much longer sentence 5 years is just nonsence.

Just to make this clear, the young fellow got 9 years for “attempting” to print his own gun via a 3d printer. Attempting. He didnt complete the gun, he didnt use the gun, he didnt have any clear indication that he was going to use the gun. These guns, from what i understand are single shot and essentially useless in the uk as you cannot get your hands on the ammunition. (although i may be out of date with this information) so for an incident other methods would be much more effective as opposed to a weak 1 shot diy… Read more »

Printing a Glock is easy today. The entire digital package is on the Internet from regular US-based gun clubs. The ammunition is harder to get, but let us not pretend you cannot get it. Providing your package omits the “Ammo4U” label, it has less than a 0.4% chance of it being physically checked. Along with privatisation, the department that handles Royal Mail security at parcel sorting hubs has been cut in half since 2017. You can buy blanks and rework them with a little know-how, again freely available on the Internet. I am not saying anything not already known to… Read more »

3 d printers are scaremongered by press and police but they still need glock magazines, they still need large amounts of 9mm ammo both quite hard to source here.
I owned a book from the US 20 years ago how to make your own sten gun with hand tools and a basic garage. Its no different. If you have the will a smooth bore is easy to make.
