James Jones, 27, ran a gun conversion business out of a suitcase which was uncovered when officers raided his home last year and arrested him.
The Collingwood Road resident is one of 37 people caught in the Boombox music store sting by Enfield Police, to catch gangsters trading guns, ammunition, weapons, and drugs.
Detective Chief Inspector Paul Harwood, who ran the major undercover operation – codenamed Peyzac – said: “It is believed that James Jones had converted many more firearms than actually recovered.
“He specialised in Olympic 38 starting pistols which he convert to live firing firearms. This particular make of starting pistol is now illegal to possess in the UK.”
