Three men were arrested after gardai foiled what they suspect was an intended gangland hit.
A semi-automatic pistol and ammo were seized after a car was stopped on Oscar Traynor Road in the capital.
Three men who were in the car aged 53, 24 and 23 were arrested and are currently being held at Ballymun and Coolock garda stations.
Sources believe the incident is related to a local feud in north Dublin and not the Kinahan-Hutch gang war.
They were detained under Section 30 of the Offences Against the State Act, which gives gardai the power to arrest anyone they suspect of being about to commit a crime, or having information relating to the commission of a crime.
Assistant Commissioner John O’Driscoll, Special Crime Operations (SCO), said: "The recent arrest of suspects and the seizure of a firearm yesterday, by the Garda National Drugs & Organised Crime Bureau (GNDOCB), following the seizure of a large quantity of drugs on Tuesday and a significant quantity of cash a number of days earlier, reflects the Garda Síochána’s unrelenting efforts to effectively tackle organised crime.”
A garda spokesman added that investigations are ongoing.
