Nearly 500 guns were handed in to police in Norfolk and Suffolk during a firearms and ammunition amnesty this month.
These included shotguns, an AK47 fully automatic assault rifle and a walking stick gun.
The amnesty, which ran from Monday, November 13 until Sunday, November 26, encouraged people to hand over unlicensed and unwanted guns to police without fear of prosecution.
The aim was to reduce the number of illegal firearms falling into the hands of criminals across the region.
In total 280 firearms were handed over in Norfolk, with 208 given in across Suffolk, as well as a large quantity of ammunition.
Richard Kennett, Firearms Manager for both Norfolk and Suffolk Constabularies, said: 'The amnesty was a real success and we're extremely pleased with how many firearms have been handed in.
'We had 225 shotguns handed in, as well as 38 hand guns, including a number of self-loading pistols, an AK47 fully automatic assault rifle and even a walking stick gun.
'Some of the guns are in working order and by taking them off the streets we are helping to make our county an even safer place to live.'
He added: 'Although gun crime isn't a big problem in our counties, it's important we take measures such as this to reduce the chances of dangerous weapons falling into the wrong hands.'
A number of imitation firearms, rifles, air weapons and deactivated firearms were also given in to officers at police stations.
The guns and ammunitions will now either be destroyed, or if they are of particular historic value, donated to a licensed museum.
