Power limits and the law
In England, Wales and Scotland, with the commencement of the Policing and Crime Act 2017, the Firearms Act 1968 has been amended to define maximum power levels that Airsoft replicas are allowed to have.
Exceeding any of these limits could ultimately result in a prison sentence, depending on what has been exceeded.
In Northern Ireland, there is no specific exception for Airsoft – in this locality the maximum is 1J (as in Japan, Italy), although it is the intention of UKAPU and other organisations to resume lobbying/campaigning for a 1.3J/2.5J once the situation in Northern Ireland supports such an endeavour.
