Two submachine guns and hundreds of rifles are among more than 1000 weapons surrendered to WA police so far during a firearms amnesty.
The amnesty began on August 1, allowing the public to hand in unlicensed firearms and ammunition without fear of prosecution, provided the firearms were not stolen or used in a crime.
Police have so far received more than 63,000 rounds of ammunition and a total of 1023 firearms, including 611 from the metropolitan are and 412 from regional WA.
Deputy Commissioner Chris Dawson said the firearms included 104 handguns, 684 rifles, 183 shotguns and two submachine guns.
"The handguns are a particular concern to us as they are often the weapon of choice of organised crime figures as they are easy to conceal but still potentially lethal," he said.
Many of the firearms were from deceased estates, police said.
People caught with an unlicensed firearm could be jailed for a maximum of three years or fined $12,000.The amnesty will finish at the end of the month.
