Do you need a license for a paintball gun in northern Ireland?

Yes you would need a firearms licence in N. Ireland however, You cannot because a paintball marker is classified as a firearm(if a mechanism has to potential of firing a projectile over 1 joule of energy out of the muzzle it is classed as a firearm) and the firearms reg act of 2005 basically states that no person can have a firearm's licence for a paintball gun because it can only be used for recreation purposes. cannot have justifiable cause to own one

Licences have only be given out to people who own a paintball centre

trust me i have been trying to get a licence for over a year now the PSNI will not allow it

If you do have a paintball marker but no licence you could get a fine.
