    • But this is a grappling hook launcher. Used for firing hooks onto roofs of tall buildings. Some times incredibly high buildings. I don't think a plain, standard line gun is designed for that.

    • The critial difference between grappling hook and line gun is that a line gun fires a much more aerodynamic weight using gun powder, while a grappling hook launches a hook (which don't like to fly straight, they prefer to tumble) using pneumatic power.
