A man jailed for life for turning replica firearms into live weapons linked to at least eight murders has been ordered to pay back £33,250.
Grant Wilkinson, 36, was convicted in 2008 of converting and supplying guns linked to 50 shootings, including the murder of Pc Sharon Beshenivsky.
Wilkinson, of no fixed abode, adapted replica Mac-10 guns in a shed in Three Mile Cross, near Reading, Berkshire.
He must pay back part of his illegal earnings or face longer in jail.
A confiscation hearing at Reading Crown Court heard that a detailed investigation into Wilkinson's assets showed he had benefited by £232,897.24 from his criminal lifestyle.
An order was made for the sum of £33,275.40 which Wilkinson must pay within six months or he will have to serve a further 12 months and still repay the money.
The sum was set after examining Wilkinson's ability to pay in light of his current assets.
During the 2008 trial, jurors heard more than 50 shootings in London, Birmingham and Manchester were linked to the guns Wilkinson converted in a shed and sold.
Eight of these were murders, mostly in London.
One of the guns was used during an armed robbery in Bradford, which led to the death of 38-year-old Pc Beshenivsky in 2005, although it was not the murder weapon.
While other converted guns were used in the murder of 15-year-old Michael Dosunmu as he slept at home in Peckham, south-east London, in February 2007, and the murder of music producer Richard Holmes in Chingford in November 2005.
Wilkinson was convicted of seven offences of converting and supplying firearms.
In 2009, he lost an appeal against his sentence. He was given a life term and must serve a minimum of 11 years.
