Light Scope

Light Scope is some kind of a pointer. It was used by Sully "The Pickle" McLeary, Amber Kearnen and an Alliance adventurer during their mission in Jade Forest on Pandaria.

In the RPG
Light Scope is a small device that comes with clamps to fit on top of any firearm. When activated (a DC 15 Use Technological Device check that takes a move action), the device shoots a tiny, focused beam of light down the barrel. When the dot hits the target, the target is within sights.
