Taser XREP delivers wireless shocks from 100 feet away

This Taser XREP can deliver a wireless electric shock from
over 100 feet away, and from the looks of it, you don't want
to be on its receiving end. Its Neuro-Muscular Incapacitation
(NMI) is the same disabling effect delivered by wired Taser weapons.

14-gram package small enough to fit into a gun barrel, yet it can
travel at 300 feet per second...Story Here
