A GUN nut used his mum's credit card to buy weapons over the internet, a court heard.
Ex-public schoolboy Ramsay Scott also trawled web-sites linked to the 1987 Hungerford massacre and other shootings.
By the time police staged a dawn raid on his East Lothian home, Scott, 20, had two fully-assembled pistols, sub-machine gun parts a
nd dum dum bullets scattered about his bedroom floor.
He also had a collection of vicious knives.
Scott of Gosford Road, Longniddry, now faces a minimum for five years in jail after pleading guilty to breaches of the Firearms Act. He pleaded guilty to eight charges some of which carry a minimum sentence of five years.
He was remanded in custody and will be sentenced next month.
The High Court in Edinburgh heard how a legitimate interest fostered at school and leading to representing Scotland in their under-19 shooting team became an obsession.
Judge Lord Uist was told a psychiatrist had examined Scott and decided he was "odd" but not mentally ill.
And solicitor advocate David Taylor insisted that Scott's fascination with guns had no "sinister hue" and he was not supplying weapons to anyone else.
Advocate depute John Scullion, prosecuting, told how Scott, a student at Durham University until his arrest, had found a way of getting American supplier to send him parts by using his mother's credit card and shipping companies as middle-men.
On August 5 customs officers at East Midlands Airport intercepted a package addressed to his mother and containing a barrel for a 9mm pistol.
They alerted Lothian and Borders police and checks showed Scott had a licence for a bolt action rifle and silencer.
When they went to his home with a search warrant, Scott admitted that the firearms in his darkened bedroom where the curtains were pegged shut, were not listed on his certificate.
"There were a number of firearms, component parts for firearms and ammunition scattered around the floor on open view," said Mr Scullion.
He went on to list a Glock 9mm pistol, a Sig Sauer 9mm pistol, barrels for use with Heckler and Koch sub machine guns other weapons parts and more than 40 "copper hollow point bullets."
The dining room had been used to make rifle and shotgun cartridges, said Mr Scullion.
Lord Uist remanded him in custody while background reports are prepared. Scott is due back in court next month to be sentenced.
