Blidworth response officers arrived in the Ricket Lane area and found Victor Staples armed with the weapon.
They challenged the 62-year-old, of Ricket Lane, to drop the rifle and had to negotiate with him for some time before he did so.
It transpired that Staples had threatened two separate drivers with a rifle at around 6pm on 12 August 2020. He also kicked one of the vehicles which caused damage.
Officers received a report of the incident and arrived within minutes of being called.
Having been arrested at the scene, Staples pleaded guilty to counts of possession with intent to cause fear of violence and one count of criminal damage and was sentenced to 13 months in prison on Wednesday 24 March.
Detective Sergeant Jamie Moore, who investigated the case, said: “Clearly a report of someone with a weapon in a public place is treated as high alert.
“Firearms officers were instantly on scene and were able to talk to Staples calmly in order to persuade him to drop his weapon and reach a safe conclusion.
“It would have been terrifying for the members of the public involved and as a force, we are working hard to put a stop to all firearms offences.
“If anyone has any information about people suspected of having a weapon of any form, please call us on 101.”
