Ricky Taylor’s home in Royston, Glasgow was searched as part of an intelligence-led operation on 14 February 2020.

Mr Taylor pleaded guilty to manufacturing slam-fire guns at the High Court in Glasgow on 15 June. He was sentenced to five years in prison on 13 July.

David Green, procurator fiscal for homicide and major crime, said: “The manufacturing of guns is an extremely serious offence.

“These types of improvised guns in particular can be dangerous to those trying to use them as well as those they’re used against.

“Police and prosecutors will continue to work together to do everything in our power to keep firearms off the streets.”
