A 62-year-old man from Telford has been jailed for four and a half years after attempting to 3D print a firearm at his home. David Boylett was caught just 15 minutes short of completing the weapon when National Crime Agency (NCA) officers raided his property.
Details of the Offence
During the raid in July 2021, investigators discovered a partially completed 3D-printed gun, along with numerous firearm components, tools, and two 3D printers. Forensic experts confirmed that Boylett only needed an additional 15 minutes to remove excess polymer and make the weapon fully functional.
An examination of Boylett's computer and memory card revealed his intense obsession with firearms. He had saved instructional videos for the same model of gun in a folder labelled 'naughty stuff'. His mobile phone also contained a video of his 3D printer producing a firearm component of the type recovered from his property.
Evidence and Investigation
Investigators found piles of documents on converting firearms, making ammunition, and using 3D printers. NCA firearms experts used the recovered files to print the remaining parts needed to complete the firearm and conducted a successful test fire. Additionally, a powerful air rifle and ammunition were seized, along with a shotgun part stolen from a vehicle in Herefordshire in April 2012.
Boylett pleaded guilty in January to attempting to possess a component part of a prohibited firearm, possessing ammunition, and possessing an overpowered air rifle without a licence. On 10 August, he was sentenced at Shrewsbury Crown Court.
Impact and Warning
NCA Senior Investigating Officer Niall Conner said: "Boylett was in the process of creating deadly weapons that could have done untold harm to individuals in our communities. The depth of his research into 3D printed firearms demonstrates his obsession and intent with the tools in his possession. Firearms crime in the UK is among the lowest in the world and we work tirelessly with partners to tackle the threat posed by illegal firearms and to protect the public."
This case highlights the ongoing efforts by law enforcement to combat the illegal production of firearms. The NCA continues to investigate and disrupt individuals who seek to manufacture weapons using emerging technologies, ensuring public safety remains a top priority.
