A Polish man who ‘held hateful views towards ethnic minorities in London’ has been found guilty of 3-D printing parts to semi-automatic firearms in his flat.
Robert Adamski, 29, of Lea Bridge Road, London, was arrested after officers from Counter Terrorism Policing London found the printer in the process of making a part needed for an FCG-9 Mk2 firearm, a 9mm calibre semi-automatic rifle.
He also had items relating to extreme right-wing ideology, and analysis of his mobile phone revealed he had shared documents on a Telegram group he headed up.
Commander Dominic Murphy, head of Counter Terrorism Policing London, said: ‘The device still needed a number of other parts as well as technical know-how to make it viable. However, the intention to make a lethal weapon was clear.’
Adamski was arrested in Walthamstow on July 11, 2024, and police found other parts for the firearm – including a magazine which could hold 25 cartridges.
Counter terrorism detectives found a string of internet searches for 3D-printed guns and how to make them.
A payment for a 3D printer was identified in his credit history in June 2024.
Adamski had also saved a guide on how to make the FCG-9 Mk2 firearm using a 3D printer on his computer.
The Crown Prosecution Service charged him with various terrorism and firearms-related in July 2024.
Following a two-week trial at Woolwich Crown Court, Adamski was found guilty of two counts of possession of a part of a firearm, possession of a document for terrorist purposes, and four counts of dissemination of terrorist publications.
He will be sentenced on 28 November.

‘This proactive counter terrorism investigation has prevented two potential firearms from falling into the hands of a man who held hateful views towards ethnic minorities in London,’ Murphy added.
‘I want to reassure the public we found no evidence Adamski was planning to use any weapons to target any particular communities or the wider public.
‘But this case shows, attempting to create or modify 3D firearms or possessing one, even without the intent to commit harm, is illegal and will bring you to attention of the police and lead to serious criminal consequences.’
