Six guns and more than 50 rounds of ammunition were handed into Beds Police during a two-week surrender campaign that ended on August 4.
These included two war trophy handguns, three air rifles and a toy replica.
Across the Bedfordshire, Hertfordshire and Cambridgeshire area, 36 weapons and more than 500 rounds of ammunition were handed in.
Chief Supt Catherine Akehurst, said: “As a result of the surrender campaign a number of illegally held, lethal firearms from across the three forces are now safely off the streets and away from criminal hands.
“Although the campaign has now ended the three forces will continue to work closely with partners and local communities to proactively tackle gun crime.”
Detective Superintendent Duncan Young added: “Initiatives like this are really important, and we were pleased to support the campaign. I am particularly pleased that so much ammunition from Bedfordshire has been surrendered; it now can’t be used by anyone intending to cause harm to our communities.
“Our work to tackle serious violence, which includes the use of weapons, continues year-round and we are committing to apprehending those involved in this kind of activity.”
If anyone knows someone who illegally owns a weapon, they should call 101 or Crimestoppers anonymously on 0800 555111.
