Mausser Chemical Streamer

The Mausser Particle Streamer can be dissasembled and upgraded to a much nicer Mausser Chemical Streamer

Here are a list of items you will need for the tradeskill

Mausser Particle Streamer
Weapons terminal
Hacker Tool
Tools or Devices terminal
Compression Chamber for Chemicals
Ranged Weapons Components terminal
Composite Barrel
Ranged Weapons Components terminal
Sheet of Curved Carbonum Plating
Armor and Clothing Components terminal or
Mechanical and Electrical Engineering Components terminal

All of the components required can be purchased from a local general store, most can also be looted from mission corpses. The hardest part will be finding a QL high enough for the gun, especially with the higher qualities
The first item you will need is the Mausser Particle Streamer, this can be found in the Weapons terminal, or looted from corpses
The Hacker Tool can be found in the Tools or Devices terminals, and both the Compression Chamber and Composite Barrel from the Ranged Weapons Components terminal, or even looted from corpses if you are lucky enough to find the correct qualities
Finally the Carbonum Plating can be found in both the Armor and Clothing Components or the Mechanical and Electrical Engineering Components terminals

You will notice with high level tradeskillers the quality of the finished gun will raise quite a bit throughout the process. Be careful with items such as the Carbonum Plating that is the last combine, purchasing one that is only 95% of the original gun may not still be 95% by the time it is required

You will need to start by dissasembling the original gun
