As part of an intelligence led operation, Gardaí from the Garda National Drugs and Organised Crime Bureau and Security and Intelligence Section searched two vehicles.
Three men aged in their 20s, 40s and 50s were arrested and a firearm was seized.
The men are detained pursuant to the provisions of Section 30 of the Offences Against The State Act 1939/98 at Dublin Garda Stations.
Speaking following the arrests, Detective Chief Superintendent Angela Willis, head of the Garda National Drugs and Organised Crime Bureau said: “The seizure of firearms and the arrest of those who are prepared to use them to take life is a priority for the Garda National Drugs and Organised Crime Bureau.”
