The Range Meter is a nice item for low level ranged users that adds to both critical chance and ranged init.
Here is a list of NPC's you will speak to throughout the quest
Here are a list of items you will need for the tradeskills and which item they are required for
First you will need two Antonio's Adaptation Factory's, these can be purchased from Vendor Antonio Stacklund
Next you need a Power Supply and a Optical Enhancer, both of these can be looted from Cargo Droid's on the docks
Once you have all the items, all that is left is to combine them in the correct order
The range meter can be equiped in your HUD 3 slot and gives a nice boost to crit increase and ranged init.
