Most airsofters are fucking deaf anyway as if they listen to the saftey brief or listen out for hits 😂
But I wonder if it's worth looking up a laser tag site near you, I hear the the gear they use now has a shock/ vibration vest that are better than the crap from the old days so when you get "hit" so he can feel it,
That way he can experience the same sort of thing we do and he will be a bit more safe and still run around and shoot guns with you and you can use it as a stepping stone/practice to get him to airsoft
