Airsoft is a lot of fun, it hurts a little when you get hit, but not for very long. I'd definitely recommend my HKMP7, but it is a Gas blowback gun. They take a lot of work to keep running, and they're pretty tricky to use. For your first gun I'd get an AEG (automatic electric gun), they are very reliable, and much easier to maintain than a Gas gun. The VFC VR16 avalon is the best AEG on the market rn.
