At the start of the year the Air Weapons and Licensing (Scotland) Act came into effect. You don’t need a licence for any ‘barreled weapons’ which are non firearms. The policing and crime bill will define ‘airsoft guns’ as non firearms, but that isn’t law yet.
Paul Cook, our Scotland Representative, has talked with Scots government and Police, and they don’t appear to have a set policy on power thresholds until the PCB is enacted. For now the police seem to regard the upper limit for airsoft as 1.3J for fully auto and 2.5J for everything else, same as the PCB airsoft exception and the old ACPO recommendation. The police are taking the new licencing law seriously, so make sure your airsoft sniper rifle is under 520fps with a .20g bb.
