If you're already age verified, what further hassle is there? If the police really wanted to get you on some sort of Replica Firearm-based charged, having a clear AK-47 will probably be no different than having a black AK-47. People who call the police about their neighbours having airsoft guns generally don't/can't distinguish between clear and coloured anyways. Just a thought.
