A 29-year-old man has been slammed with a 15-year prison sentence after trying to 3D print parts for a deadly sub-machine gun, following a sharp investigation by Counter Terrorism Policing London.
3D Printer Busted Mid-Gun Build
Robert Adamski, a Polish national living on Lea Bridge Road, E10, was caught red-handed when police raided his flat. Officers found a 3D printer halfway through making a crucial piece for an FGC-9 Mk2 — a lethal 9mm semi-automatic rifle.
His home was also packed with gun parts, including a magazine that could hold 25 rounds. Records show he bought the 3D printer just a month earlier, in June 2024.
Links to Extreme Right-Wing Terror Revealed
But it wasn’t just illegal weapons. Police found Adamski hoarding extremist right-wing material and uncovered his role as an admin of a Telegram group sharing terror docs. Phone forensics revealed he was distributing terrorist content online.
Commander Dominic Murphy, head of Counter Terrorism Policing London, said:
“This sentence sends a strong message about the dangers and illegality of attempting to produce firearms with 3D printers.
Thanks to swift police action, Adamski was stopped before he could complete a working gun.
While he possessed extreme materials, there’s no evidence he planned to target specific groups or the public. But this case proves trying to create or own 3D-printed firearms without intent to cause harm still leads to serious consequences.”
Trial Shocks with Terror and Gun Charges
Arrested in Walthamstow on 11 July 2024, Adamski was charged with terrorism and firearms offences six days later. His two-week trial at Woolwich Crown Court ended with a guilty verdict on several counts:
- Possession of a document for terrorist purposes
- Four counts of disseminating terrorist publications
- Two counts of possessing prohibited firearms (to which he pleaded guilty)
On 27 January, the Old Bailey hit him with 15 years behind bars plus two years on licence.
