I think there is a big difference between what he is talking about what average weekend airsoft really is.
I use to use my airsoft glock 19 to train cheaply in my house for the rare times I get range time with my 9mm. About as far as airsoft (truly a game like paintball), and training with live ammo are two completely different things, and shouldn't be mistaken. Kids that see this video that play airsoft, turn 18, then buy there first AR/AK go run it out in the bush alone thinking they're airsoft experience is enough will just end up hurting themselves, or someone else.
I like that lathe in his garage!
