I'm not from Europe (but that's where I got my first airsoft gun). My mom hates guns (from NERF to Airsoft to BB to real guns), and took away every single airsoft gun I had because she knew that the police would shoot first and ask questions later. They were right- I could have gotten killed. It was dumb to run around looking like an insurgent. I really did- I had a baseball cap, a scarf over my face, ballistic sunglasses, grenades, several differnt airsoft guns (none of came with orange tips).
All the cartons said 18+, but I was able to walk right in and buy my first one at age 11.
