A 22-year-old man found in possession of a machine gun and stun gun has received a 10-year jail term.
Police arrested Joel Simmonds in July 2005, after a search of his house in Tavy Close, Lambeth, south east London, found a fully-loaded Mac-10 pistol.
When arrested, officers said Simmonds had a mobile phone screen saver with an anti-police logo and a picture of him pointing a shotgun.
Searching another property in Denmark Hill, police found Simmonds' stun gun.
Gun crime 'deterrent'
It was found alongside body armour and cash.
Unemployed Simmonds was convicted in July of one count of possession of a firearm with intent to endanger life, one of possessing a prohibited weapon and one of possession of ammunition.
After the sentencing, investigating officer Det Sgt Ian Titterrell said: "The lengthy sentence given to Joel Simmonds should be a deterrent to those involved in gun crime.
"It further reinforces the commitment of the Metropolitan Police Service and Trident and we will continue to actively target those who are willing to use and carry firearms," he added.
