Yeah airsofts can certainl6,sting, but they have regulations on how,fast they can fire for safety reasons. UT airsofts are made for “war games”, so I don’t think it can be argued they were being irresponsible. They were using tools designed for what they were doing. Prop gu s however still fire the same velocities as real guns. Prop guns are usually real guns that fire blanks and or real ammo.
A prop gun should be exactly that and nothing more. If it is a fully functional gun that is shooting blanks, then it better have been completely disabled by a gun smith. Or modified so that it can’t fire a projectile. Maybe a plug although that is probably not safe either. BTW, I am not a gun smith.
And I agree with you, blanks are just as dangerous. But then again, blanks are designed to be fired out of a functional gun.
