The XREP is basically “a fin-stabilized, self-contained round with no wires leading back to the gun and a maximum range of 100 ft.” Video after the break.

The XREP punctures the target with multiple probes, and then unspools to dangle from the unfortunate belligerent’s body, all the while applying Taser’s infamous rapid-fire electrical pulses. As an added bonus, any helpful passerby trying to yank the XREP out of the target before the 20-second discharge cycle is finished will also get zapped, thanks to a “hand-trap wire” that’s nestledin among the other hanging cables
