To be honest, after all the talk we have on here and the UKARA database and questions etc, this question even came up!!.
As mentioned, your more at risk of being arrested or possibly losing your life if it goes wrong, which we here don't want to see
My brother and his friend got questioned back on Xmas eve 2001 when his friend had a gun lighter with him and lit up a fag, helicopter was out, cops out and armed police. Only knocked on our door as I let the dogs out before bed and the chopper spotted the flood light.....on the bad side there was confusion and about 5 hours between them being out and the knock on the door.....I think there was an incident in the adjacent village and wires crossed....I enjoyed it though!!!
Halloween isn't for tac gear or rifs, it's not worth the risk for a few minutes of fun ruining your life and others
Do what I'm doing, walking around in my pants while my kids knock on the door!!! Hahaha
Ok I'm not really, I'm sitting in the house with the lights off !!!
