Six men have admitted being members of the UVF at the beginning of their trial in Belfast Crown Court.
The judge released them on bail pending completion of pre-sentence reports in June when they will be sentenced.
The men, from Counties Antrim and Armagh, were found wearing paramilitary uniforms when police raided a disused store in Monkstown three years ago.
Two other men admitted having guns and items related to the UVF in the store on the outskirts of Belfast.
The men had all originally denied being involved in the organisation.
They claimed they were members of a flute band, but when they appeared at Belfast Crown Court on Wednesday, all admitted the charge.
The men are Joseph Crawford from Fairway, Richard Morrow from Lynn Road, Dale Magill of Inverview Park, Ian Davidson from Waterfall Road and Philip Clarke from Cairngorm Drive, all Larne and John Rolston, from Alexander Crescent in Armagh.
Two others, Colin Greer from Ards Park in Monkstown and Robert Anderson from Chaine Memorial Road in Larne, pleaded guilty to having the guns and UVF items.
