How to Unlock Weapon Perks

Just under the weapon image are two buttons:VersionandPerk Tree. Which Version you have will determine which perks you have access to. On the Version screen, you’ll see that each weapon has four tiers.
Each Tier can be unlocked at the indicated weapon XP level indicated in the listing above. The operative word here is “can.” Once you reach this weapon XP level, you may then spend an Armoury Data piece to unlock the tier.

Armoury Data
Armoury Data can be found throughout the Campaign or Operations missions. Also, the type of data piece that you will find depends on theThreat Level(difficulty) you are playing on. For instance,MinimalandAveragesettings will only ever furnish a Green Armoury Data. The Green pieces can be used to unlock the Master-Crafted Tiers of weapons. See all three types of Armoury Data below.
