The consequences usually revolve around a fine, ranging from £0 - £500. Its a serious thing taking Airsoft Rifles out into the streets (or park). People would call the police even if they knew it wasnt real and you were jsut messing around due to past offences made with the classic BB Gun. As an Airsoft user myself, i would advise you never to leave the security of your backyard with a realistic airsoft gun, and never aim it in the general direction of another person, friend or enemy. If someone is injured (loss of eye sight for example) Prison could well be involved.
