Even if you get age verified, we should warn you that the FAMAS was the first AEG ever designed in like 1991. It's an ancient design and somewhat primitive. It's also rarer and harder to find. I don't see them often.
If you like the feel of the FAMAS, I'd recommend looking at some of the more modern AEG bullpups like an AUG (v3 gearbox), P90 (v6 gearbox), Tavor (v6 gearbox), etc.
