A 24-year-old Melbourne man is facing a number of firearms charges after police found a loaded AK-47 machine gun in his home.
Three other firearms – a semi-automatic rifle, a revolver and a sawn-off shotgun – were also found at the man's Glenroy home on Friday morning.
Detectives from the Moreland Crime Investigation Unit raided the house on Gladstone Parade at 9.30am.
They arrested the man and he faced Broadmeadows Magistrates Court late on Friday afternoon.
He was charged with trafficking firearms, being a prohibited person possessing firearms and possessing ammunition.
A number of Russian-designed AK-47 weapons have been seized by police in Melbourne in recent months, with a Border Force expert estimating there could be thousands of them in Australia.
Former Border Force Commissioner Roman Quaedvlieg said in August many were housed with collectors.
“They were originally built in the Soviet Union in the late '40s. Over time there’s been about 100 million or so manufactured in the global market. In the '50s and '60s it was quite easy to get them into the country,” Mr Quaedvlieg told 3AW.
“They’re a very durable weapon, they’re very robust, they’re simple to use and don’t perish easily, so they stay in existence for a long time.
“You can punch out several hundred rounds a minute, they’re a scary weapon."
Mr Quaedvlieg also questioned why Australia allowed the importation of assault rifles when they appear to be creating “unnecessary risk”.
