It usually means you can shoot 3 bbs at a time, and shoot continuously by holding the trigger and just racking the shotgun back and forth.
if you mean orange tip that it is a airsoft gun and that its not a real gun so you dont get shot by cops. if your talking about the bright colors on guns in the UK its the law unless you have a licence.
No; their ammunition is too big and dangerous to be shot at people. Only airsoft guns are allowed in airsoft.
Yes.
Yes
yes
Yes.
Not really. I mean it stops an airsoft shot, but it will not properly defend you during a terrorist attack, or nuclear fallout You can buy airsoft plate carriers, which could technically hold bullet proof plates in them, but they are not meant for this and should not be used in that way. But you can buy airsoft proof plates which will absorb pretty much the whole force of a bb's impact, effectively protecting you from airsoft guns if that is what you meant.
It's something which could potentially happen, but isn't likely to when hit with airsoft pellets.
The same as any other weapon, causing injury
If you mean you don't have to cock after every shot, yes there are pistols like that. But there is no firearm you don't have to cock at some point.
Yes but there hurt
yes they are reusable
