Three men stopped with rifles and handguns in south Armagh were allegedly planning to bury the weapons, the High Court has heard.
Two of the suspects denied any intention to use the guns, while a third insisted he had no links to either the Real IRA or other outlawed groups, a judge was told.
Brian Sheridan (34) of Avonmore, Blackwatertown; Brian Cavlan (35) from Circular Road, Dungannon; and Dominic Dynes (39) of Castleblaney, Co Monaghan, were arrested after police stopped and searched a car in Keady on April 22.
They are each charged with possession of firearms and possession of articles for use in terrorism. An AKM assault rifle, two bolt-action rifles and a silver Colt .45 pistol were found in the search.
All three men were refused bail.
